The MX4-R2 expansion module provides temperature and frequency input capability to the C5 and future generations of FW Murphy Controllers using CAN proprietary communication with enhanced diagnostics. Serial RS-485 port and 2 Ethernet ports also provide other communication methods to work with any Modbus RTU or Modbus TCP/IP client device. The MX4-R2 module features 18 thermocouple / 9 RTD inputs and 1 magnetic pickup input. MX4-R2 is backward compatible to MX4.

The MX5-R2 expansion module provides input/output capability to the C5 generation and future generations of FW Murphy Controllers using CAN proprietary communications with enhanced diagnostics. Serial RS-232 or RS-485 ports and 2 Ethernet ports also provide other communication methods to work with any Modbus RTU or Modbus TCP/IP client device. The MX5-R2 module features 24 Digital inputs, 16 Digital outputs, 10 Analog inputs, 4 Analog outputs and 1 magnetic pickup input. MX5-R2 is backward compatible to all models of the MX5.

Any combination of MX-Series modules can be added to enable Digital and Analog I/O and Temperature inputs for communication and monitoring by the master controller.
