Remote I/O modules with Profinet bus coupler

Solidot Profinet remote I/O module PN4 with 16 digital channels

You need a handful of signals somewhere in the plant where there is no PLC — and you do not want to build a bus coupler, a power supply and half a cabinet around them. That is what the PN4 is for: electronics, PROFINET port and terminals sit in one housing 25 mm wide. Wire it up, load the GSDML into your project, done. 🏭 Typical applications Distributed signals along conveyors: collect limit switches, photoelectric sensors and valves at the conveyor section instead of running twenty wires back to the main cabinet. Expanding an existing S7: when the slots on the central rack are full, you simply hang the PN4 on the existing PROFINET network. Machine retrofit: the existing controller stays, the peripherals move to PROFINET — without replanning the wiring inside the machine. 🔌 Versions with 16 channels PN4-1600B: 16 digital inputs, PNP, 24 V DC, 4 mA input current, 3 ms filter time PN4-0016B: 16 digital outputs, PNP, max. 500 mA per channel, with overvoltage and overcurrent protection PN4-0808B: 8 inputs and 8 outputs in the same housing All channels are optically isolated (500 V AC) and rated for resistive and inductive loads. ⚙️ Core specifications Bus: PROFINET, 2 x RJ45 (100 Mbit/s), up to 100 m per segment, CAT5 Power supply: 24 V DC (18 – 36 V), galvanic isolation 500 V AC Environment: -10 °C to +60 °C operating, -20 °C to +75 °C storage, 95 % relative humidity without condensation, IP20 Form factor: 102 x 72 x 25 mm, 130 g, 35 mm DIN rail, pluggable spring-loaded terminals Diagnostics: a green LED next to every channel, plus PWR, RDY, SF and BF on the housing 🔗 Compatibility The PN4 registers as an ordinary PROFINET device. Tested and in use with Siemens S7-1200 and S7-1500 (TIA Portal), it works just as well with CODESYS controllers, Beckhoff TwinCAT and any other master that can read a GSDML. No vendor software, no licence. 🔧 Mounting and commissioning The module clips onto a 35 mm DIN rail. The terminal blocks are pluggable — you wire them up in the cabinet and plug them on afterwards. To swap a module in the field you pull the block, take the device out and plug the block back on: not a single wire is disconnected.

Solidot Profinet remote I/O module PN4 with 32 digital channels

32 signals on 25 mm of rail width — that is why the PN4 ends up in tight cabinets. You save the bus coupler, a separate power supply and the marshalling terminals: electronics, PROFINET port and pluggable terminals sit in one housing. Wire it up, load the GSDML, done. 🏭 Typical applications Compact sub-distribution: where a slice I/O system with coupler and end cap no longer fits, the PN4 still goes on the rail. Collection point for sensors: gather 32 limit or proximity switches at one station and send them back over two PROFINET wires. Expanding existing plants: slots on the central rack full? The PN4 joins the existing PROFINET network without touching the controller. 🔌 Versions with 32 channels PN4-3200B: 32 digital inputs, PNP PN4-0032B: 32 digital outputs, PNP, max. 500 mA per channel PN4-1616B: 16 inputs, 16 outputs PN4-2408B: 24 inputs, 8 outputs PN4-0824B: 8 inputs, 24 outputs Inputs 24 V DC PNP with 4 mA input current and 3 ms filter time, outputs with overvoltage and overcurrent protection. All channels optically isolated (500 V AC). ⚙️ Core specifications Bus: PROFINET, 2 x RJ45 (100 Mbit/s), up to 100 m per segment, CAT5 Power supply: 24 V DC (18 – 36 V), galvanic isolation 500 V AC Environment: -10 °C to +60 °C operating, -20 °C to +75 °C storage, 95 % relative humidity without condensation, IP20 Form factor: 102 x 72 x 25 mm, 130 g, 35 mm DIN rail, pluggable spring-loaded terminals Diagnostics: a green LED next to every channel, plus PWR, RDY, SF and BF on the housing 🔗 Compatibility The PN4 registers as an ordinary PROFINET device.

Solidot Profinet remote I/O module PN4 with 12 relay outputs

When you need to switch loads a transistor output cannot handle — contactors, solenoid valves, indicator lamps, circuits on a different potential — you need relays. The PN4 relay module brings twelve of them, connects straight to PROFINET and does without a bus coupler and without a row of interposing relays. 🏭 Typical applications Contactor control: switch motor contactors straight from the controller, with no interposing relay in between. Separate voltage circuits: potential-free contacts for circuits that are not on the controller's 24 V potential. Retrofitting older plants: keep the existing relay wiring and move only the control side to PROFINET. 🔌 Versions PN4-0012J: 12 relay outputs, 2 A per channel, for resistive and inductive loads, 4 channels per common terminal PN4-1612J: adds 16 digital inputs, wired as NPN or PNP The relay outputs are doubly isolated via optocouplers and relays, withstand voltage 500 V AC. Every channel has a green LED right at the terminal. ⚙️ Core specifications Bus: PROFINET, 2 x RJ45 (100 Mbit/s), up to 100 m per segment, CAT5 Power supply: 24 V DC (18 – 36 V), galvanic isolation 500 V AC Environment: -10 °C to +60 °C operating, -20 °C to +75 °C storage, 95 % relative humidity without condensation, IP20 Form factor: 102 x 72 x 25 mm, 130 g, 35 mm DIN rail, pluggable spring-loaded terminals Diagnostics: a green LED next to every channel, plus PWR, RDY, SF and BF on the housing 🔗 Compatibility The PN4 registers as an ordinary PROFINET device. In use with Siemens S7-1200 and S7-1500 (TIA Portal), and equally with CODESYS controllers, Beckhoff TwinCAT and any master that can read a GSDML. On the PN4-1612J you decide between NPN and PNP by wiring — so you are not tied to one sensor family. 🔧 Mounting and commissioning The module clips onto a 35 mm DIN rail. The terminal blocks are pluggable — you wire them up in the cabinet and plug them on afterwards. To swap a module in the field you pull the block, take the device out and plug the block back on: not a single wire is disconnected.

Solidot Profinet remote I/O module PN4 with 4 analog channels

Acquire or output analog values where they occur — without long measuring cables that pick up every disturbance on the way to the cabinet. The PN4 analog module takes 25 mm of rail width right at the machine and connects to your controller over PROFINET. No bus coupler and no separate power supply required. 🏭 Typical applications Pressure, level and temperature transmitters: read 4–20 mA sensors close to the process instead of routing the current loop across the shop floor. Setpoints for variable frequency drives: output 0–10 V or 4–20 mA directly at the drive. Proportional valves and actuators: provide analog manipulated variables in the field. 🔌 Versions with 4 channels PN4-A40V: 4 voltage inputs, selectable -10 – +10 V, 0 – +10 V, -5 – +5 V, 1 – 5 V, input impedance ≥ 2 kΩ PN4-A40I: 4 current inputs, selectable 0 – 20 mA or 4 – 20 mA, input impedance 100 Ω PN4-A04V: 4 voltage outputs, load impedance ≥ 2 kΩ PN4-A04I: 4 current outputs, load impedance ≤ 200 Ω 16 bit resolution, ±0.1 % accuracy, sampling rate ≤ 1 ksps. The measuring range is parameterised per channel in the PROFINET project, not set by jumpers on the device. ⚙️ Core specifications Bus: PROFINET, 2 x RJ45 (100 Mbit/s), up to 100 m per segment, CAT5 Power supply: 24 V DC (18 – 36 V), galvanic isolation 500 V AC Environment: -10 °C to +60 °C operating, -20 °C to +75 °C storage, 95 % relative humidity without condensation, IP20 Form factor: 102 x 72 x 25 mm, 130 g, 35 mm DIN rail, pluggable spring-loaded terminals Diagnostics: a green LED next to every channel, plus PWR, RDY, SF and BF on the housing 🔗 Compatibility The code value ranges match the common PLC formats: 0 – 27648 and -27648 – +27648 correspond to the Siemens format, and the full 16 bit scaling (0 – 65535) is available as an alternative. Blocks from existing S7 projects therefore carry over without rescaling. The module is integrated via its GSDML — with Siemens S7-1200 and S7-1500, CODESYS, Beckhoff TwinCAT and any other PROFINET master. 🔧 Mounting and commissioning The module clips onto a 35 mm DIN rail. The terminal blocks are pluggable — you wire them up in the cabinet and plug them on afterwards. To swap a module in the field you pull the block, take the device out and plug the block back on: not a single wire is disconnected.

Solidot Profinet remote I/O module PN4 with 8 analog channels

Eight analog channels on 25 mm of rail width, right at the machine instead of in the main cabinet. That saves you long measuring cables and the bus coupler along with them — electronics, PROFINET port and pluggable terminals sit in one housing. 🏭 Typical applications Measuring points on process plants: read eight pressure or level transmitters at one station without running eight current loops back. Multi-axis setpoints: supply several variable frequency drives or proportional valves from a single module. Test benches and pilot rigs: many analog channels in a small space, without a rack. 🔌 Versions with 8 channels PN4-A80V: 8 voltage inputs, selectable -10 – +10 V, 0 – +10 V, -5 – +5 V, 1 – 5 V, input impedance ≥ 2 kΩ PN4-A80I: 8 current inputs, selectable 0 – 20 mA or 4 – 20 mA, input impedance 100 Ω PN4-A08V: 8 voltage outputs, load impedance ≥ 2 kΩ PN4-A08I: 8 current outputs, load impedance ≤ 200 Ω 16 bit resolution, ±0.1 % accuracy, sampling rate ≤ 1 ksps.

Solidot Profinet bus coupler for XB6 remote I/O with power supply unit and end cap

⚠️ Remaining stock. The XB6 series is being phased out. Its successor is the XB6S coupler kit from the XB6S series. While stock lasts you can still get XB6 — for extending an existing installation that is often exactly what you want, because coupler and modules have to match. 🔌 Bus coupler with power module and end capThe coupler is the head of an XB6 station: it talks to the controller over the fieldbus and supplies the attached I/O modules through the 5 V backplane. Power module and end cap are included. Available for EtherCAT, EtherNet/IP, Modbus TCP, PROFIBUS DP and PROFINET — the modules behind it stay the same in every case. ⚙️ Series characteristics5 V backplane bus, supplied with 18 – 36 V DC through the power module in the coupler kit-10 °C to +60 °C operating, -20 °C to +75 °C storage, 95 % relative humidity without condensation, IP2035 mm DIN rail, pluggable spring-loaded terminals, a green LED next to every channelModule 106 x 73 x 25.7 mm, coupler and power module 106 x 61 x 22.5 mm Technically XB6 is not a risk: the series has been in the field for years, the modules are mature and the documentation is complete.
