I/O Interface Modules with digital inputs and outputs controlled via Modbus RTU protocol over a high-speed RS485 serial bus. The modules can be installed even hundreds of meters away, simplifying and reducing wiring costs.
Equipped with galvanic isolation on both input and output ports. The static outputs, implemented with high-current MOSFETs, are protected against permanent short circuits, overvoltage, and overtemperature.
High-brightness LEDs provide a visual status indication for all I/O, with a power-on self-test function.
A programmable timer allows forcing outputs to an inactive state in case of communication loss.
Configurable over the fieldbus with direct Modbus commands, function block libraries, CoDeSys, and PC-based software.
Easy integration into the CoDeSys “PLC Configuration” through configuration files.
Modbus protocol extensions enable I/O updates at 1Mb/s in a single frame exchange.
