Product information "Solidot EC4-A04V – EtherCAT Remote I/O, 4 × AO voltage"

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.

Manufacturer "Solidot"
Solidot was only founded in 2012 and is therefore still a relatively young company. It is now a leading manufacturer of remote I/O in Asia. The company specializes entirely in remote I/O and offers a wide variety of different bus couplers, form factors and assemblies.
