Ethernet Remote I/O Modules

Semaphore offers a new range of affordable Ethernet Remote Modules of compact size and monoblock construction that can be fixed easily on DIN rail.

The modules connect a wide variety of electrical, electronic, and mechanical devices and sensors -- such as pumps, temperature and pressure transmitters, motors, and more — to computers and applications over standard Ethernet networks (Modbus/TCP), RS485 (Modbus RTU), or other controllers and PLCs.

Each remote I/O module has its own Ethernet Modbus TCP/IP port making it easy to connect the modules to each other with up to 100 meters of CAT5 cable, or even longer distances using fiber optic switches.

There are several types of Ethernet remote I/O modules available with different I/O formats.
