Serial I/O Modules

Serial I/O modules uses a standard RS-232/422 or RS-485 interface to transmit a variety I/O signals including sensor, voltage, digital, relay, TTL and open collector.

Our wide range of serial I/O modules can be remotely controlled via RS-485 serial bus using DCON and Modbus RTU/ASCII protocols. The selectable transmission speed of the RS-485 port is up to 115,200 bps.

These remote serial I/O units can be used to monitor and control analogue signals such as volts, mA, temperature and digital status signals such as alarms, whilst digital outputs can control devices such as pumps.

Our wide range of remote serial I/O modules are used in distributed process control, factory automation and other industrial applications.
