Modbus Master/Slave Serial Enhanced Communication Module, eXTreme Temp

MVI56E-MCM/MCMXT

Modbus Master/Slave Serial Enhanced Communication Module, eXTreme Temp

MVI56E-MCM/MCMXT

The MVI56E-MCM and MVI56E-MCMXT act as input/output modules on the ControlLogix backplane, making Modbus data appear as I/O data to the processor. Two independently configurable serial ports can operate on the same or different Modbus networks. The MVI56E-MCM is designed for standard process applications and the MVI56E-MCMXT is designed for the Logix-XT™ control platform, allowing it to operate in extreme environments. It can tolerate higher operating temperatures, and has a conformal coating to protect it from harsh or caustic conditions.
