Industrial Ethernet Media Converter – MCI-422 MM/SM

Industrial Ethernet Media Converter MCI-422

The MCI-422 is Industrial Converter with a simple and cost effective Ethernet device suitable for use in a wide range of factory and building automation applications. The device can be used as either a switch or a dual channel converter. Two models are available – The SC2 for use on up to 2 km (1.24 mi) of multimode fibre and the SC30 for single-mode applications to 30 km (18.6 mi).

The unit is designed for DIN rail mounting into industrial cabinets allowing simple Ethernet connections to be established between PLCs, I/O units, drives, inverters and HMIs. The dual power input makes the unit ideal in these types of application and the fault relay can be connected to an I/O unit to provide simple network management.

Designed to work in industrial environments with its IP 31 Aluminium housing and a wide temperature specification the MCI-422 is an ideal automation solution,

The Industrial Ethernet Media Converter MCI-422 is so easy to use, simply connect power to the screw terminals and plug in your RJ-45 cables. If you plan to use the fault contacts a DIP switch allows configuration whilst LEDs provide simple diagnostics if required.
