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.
