Remote I/O expansion units

ICP-DAS-RU-87P8-G.jpg

Remote I/O expansion units are used to expand the I/O count of any existing or new automation or control system. They can monitor and control process signals such as volts, mA and temperature, or switches and digital signals. They integrate seamlessly with SCADA, PLC, PAC and PC based software systems, making them ideal for all industrial applications.

Ethernet expansion units are specifically designed for signals that need to be measured or controlled using an Ethernet network interface, using fieldbus protocols such as: Modbus TCP, ProfiNET, Ethernet IP or EtherCAT.

Serial expansion units are specifically designed for signals that need to be measured or controlled using a Serial interface, using fieldbus protocols such as: Modbus RTU/ASCII, ProfiBUS, or CAN.  Universal serial bus expansion units are specifically designed for signals that need to be measured or controlled using a USB interface.
