If you want to connect sensors and actuators to a controller in a decentralized way – without running every single wire all the way back to the main control cabinet – the Solidot EC4 series offers a compact EtherCAT remote I/O system. The modules sit right where the signals originate – on the machine or in the field distribution box – and transmit all inputs and outputs to the controller over a single EtherCAT cable. This saves wiring, terminals and space in the central cabinet. 🏭 Typical applications Decentralized machine modules: Each assembly gets its own I/O module, connected via a continuous EtherCAT line – new modules are simply daisy-chained on. Relieve the control cabinet: Instead of hundreds of wires running to the central cabinet, only two RJ45 lines per module are needed. Fewer cable ducts, fewer terminals, a clearer system. Retrofit with an EtherCAT master: Extend existing Beckhoff TwinCAT or CODESYS controllers with decentralized I/O without enlarging the central PLC. Mixed signal types: Digital, analog (current/voltage), relay, temperature or encoder – a suitable module for every signal type from the same building-block system. 🌐 EtherCAT: one cable for all signals EtherCAT transmits the process data of all daisy-chained modules with very low latency over a line topology. Each EC4 module has two RJ45 ports (IN/OUT, 100 Mbps) and is looped through – no additional switch required. The module is read into the master via the EtherCAT device description file (ESI) and is ready to configure immediately. 💡 Working with EtherNet/IP instead of EtherCAT? The same modules are available as the Solidot EI4 series (EtherNet/IP) – same hardware, same building-block system, just a different fieldbus. 🔗 Compatibility As a standard-compliant EtherCAT slave device, the EC4 series works with any EtherCAT master – such as Beckhoff TwinCAT or CODESYS. Integration is vendor-independent via the ESI file. 🔌 Design and connection Removable spring-clamp terminals: Power supply and I/O sit on removable terminal blocks – when replacing a module, the block is simply unplugged and the wiring stays in place. DIN-rail mounting: 35 mm DIN rail, compact housing (102 × 72 × 25 mm), passive cooling – no fan, no maintenance. Power supply: 24 V DC nominal, permissible 18 – 36 V DC. Status via LEDs (PWR, RUN, ERR) on each module. ⚠️ Limitations stated honestly Protection rating IP20 – for a control cabinet or protected enclosure, not for the unprotected field environment. Power supply exclusively 18 – 36 V DC, no AC supply. Operation from -10 °C to +60 °C (passive cooling). Standard process I/O – no functional-safety (safety-rated) inputs/outputs. A separate safety controller is required for emergency stop and similar functions. EC4 modules are slave devices and require an EtherCAT master – they do not replace a controller. 🏷️ Manufacturer and reliability Solidot (s'Dot) specializes in industrial networking and remote I/O technology. The EC4 modules are CE- and RoHS-compliant and built for industrial use; on the analog modules the channels are galvanically isolated (500 V, optocoupler). spstiger offers the series with expert advice and support.

If you need to read or switch digital signals right at the machine – no control cabinet, no terminal wiring, and even where things get wet, dusty or full of swarf – the Solidot EC7A series is built for it. Rugged field I/O in an IP67 metal housing that simply plugs into the line via M12 connectors. 🏭 Typical applications Decentralised instead of a cabinet: connect sensors and actuators right at the process – saving wiring and junction boxes. Conveyor and packaging: field-level I/O on moving or distributed machinery where IP20 modules won't survive. Washdown areas: food, filling, cleaning zones – the IP67 metal housing handles splash water and cleaning. Retrofit: extend an existing EtherCAT line with rugged field peripherals without touching the controller. ⚙️ Key specifications 16 digital channels, PNP – depending on the variant 16 inputs, 16 outputs or 8 + 8. 24 V DC supply (18–30 V), outputs rated 0.5 A per channel, overcurrent protection. Green status LED per channel, IP67, operating temperature −25 to +70 °C. 🔌 Connection technology All-M12 connectivity: bus via 2× M12 (D-coded), I/O via M12, power via M12. Standard cables, plugged rather than screwed – quick to install and to replace. 🌐 EtherCAT in the field Standard EtherCAT: connects to common EtherCAT masters such as Beckhoff TwinCAT. Configuration file (ESI) supplied by Solidot. 🏷️ Manufacturer and reliability Solidot (Nanjing Solidot Electronic Technology) specialises in decentralised I/O and fieldbus technology. The EC7A modules are designed for continuous industrial use in Europe, CE-marked and RoHS-compliant. 🔧 Mounting and dimensions Direct mounting via two fixing holes. Dimensions 226 × 63 × 33 mm, weight approx. 0.66 kg.

If you want to connect sensors and actuators to a controller in a decentralised way – without running every single wire all the way back to the main cabinet – the Solidot EC5R series offers a compact, low-profile EtherCAT remote I/O system. The modules sit where the signals originate – on the machine or in the field distributor – and transmit all inputs and outputs to the controller over a single EtherCAT cable. Status LEDs right next to each channel show every input and output directly at the terminal point. This saves wiring, terminals and space in the central cabinet – and speeds up troubleshooting. 🏭 Typical applications Decentralised machine modules: Each assembly gets its own I/O module, connected via a continuous EtherCAT line – new modules are simply added in series. Relieve the control cabinet: Instead of hundreds of wires to the central cabinet, only two RJ45 cables run per module. Fewer cable ducts, fewer terminals, a clearer system. Retrofit with an EtherCAT master: Extend existing Beckhoff TwinCAT or CODESYS controllers with decentralised I/O without enlarging the central PLC. Mixed signal direction: From a pure 32-channel input or output module to the 16/16 combination – on the 1616B+ model, 16 channels are freely configurable as inputs or outputs. So one variant still fits even when requirements change. 🌐 EtherCAT: one cable for all signals EtherCAT transmits the process data of all chained modules with very low latency over a line topology. Each EC5R module has two RJ45 ports (IN/OUT, 100 Mbps) and is daisy-chained – no additional switch required. The module is imported into the master via its EtherCAT device description file (ESI) and can be configured immediately. 🔗 Compatibility As a standard-compliant EtherCAT slave device, the EC5R series works with any EtherCAT master – such as Beckhoff TwinCAT or CODESYS. Integration is vendor-independent via the ESI file. The inputs of the 3200 and 1616B types accept either NPN or PNP sensors – handy when both sensor types exist in your installed base. 🔌 Design and connection Tool-free spring terminals: Power supply and I/O are connected via push-in spring terminals – insert the conductor, done, no screwdriver needed. DIN-rail mounting: 35 mm DIN rail, compact low-profile housing (182 × 58 × 34 mm), passive cooling – no fan, no maintenance. Power supply: 24 V DC, permissible 20.4 – 28.8 V DC. Green status LED per channel, right at the terminal. ⚠️ Limits stated honestly Protection rating IP20 – for control cabinets or protected enclosures, not for the unprotected field environment. Power supply exclusively 20.4 – 28.8 V DC, no AC supply. Operation from -20 °C to +60 °C (passive cooling). Standard process I/O – no functional-safety (safety) inputs/outputs.
