Odot IP-PN-8IA IO-Link-Master PROFINET, 8x Class-A Ports, IP67

If you want to bring IO-Link sensors and actuators into a PROFINET controller directly from the field, without dedicating a separate cabinet module to every channel, the Odot IP-PN-8IA is a compact IO-Link master in an IP67 housing. The module acts as a PROFINET IO device and provides 8 IO-Link Class A ports that together support up to 16 digital inputs or outputs – right at the machine, with no extra control cabinet.

🏭 Typical Applications

• IO-Link in the field instead of the cabinet: sensors and actuators connect directly to the module; diagnostic data travels to the controller over PROFINET.

• Retrofitting Siemens PROFINET systems: add decentralized IO-Link channels to an existing S7 controller.

• Harsh environments: the IP67 housing allows installation right on the machine, in moisture, dust or oil mist, with no extra protective enclosure.

• Mixed IO-Link topologies: up to 8 IO-Link devices per master, each port individually configurable via Pin 2/Pin 4 as DI, DO or IO-Link.

🌐 PROFINET and IO-Link: Two Protocols, One Module

The IP-PN-8IA is a standards-compliant PROFINET IO device with RT real-time communication (cycle time from 1 ms, up to 1440 bytes of input and output data). MRP ring redundancy is not supported. On the field side it works as an IO-Link V1.1.4 master with 8 Class A ports (COM1–COM3, adaptive transfer rate), maximum cable length 20 m per port.

🔌 Design and Connections

• 8x IO-Link Class A: M12, A-coded, 5-pin, each port individually configurable as IO-Link, digital input (PNP, type 3) or digital output (PNP, 0.5 A resistive).

• 2x PROFINET network ports: M12, D-coded, 4-pin, daisy-chained (1 in/1 out) – no additional switch required.

• Separate supply: Us (system voltage) and Ua (field voltage), each 24 V DC, max. 8 A, via 2x M12 L-coded, 5-pin.

• Diagnostics: over-/undervoltage detection, communication status, built-in temperature sensor with automatic warning if exceeded.

• Plug and play, online update: automatic device identification, firmware update without disassembly.

⚠️ Limitations, Stated Plainly

• No MRP/IRT – ring or media redundancy is not supported.

• Supply is 24 V DC only, no AC power option.

• Operating range -30°C to +60°C, storage -40°C to +85°C.

• 8 IO-Link ports are fixed – additional channels require more masters or additional IO-Link hubs.
