Emerson Ovation 1C31227G01

The 1C31227G01 is not an analog input module itself; it is the Personality Module (PMOD) that works together with the 1C31224G01 Electronics Module to form a complete 8-channel analog input channel in the Emerson Ovation™ DCS. The PMOD provides the physical field-wiring termination, input impedance matching, and surge protection, while the EMOD contains the A/D converter and communication interface. For 4-20 mA current inputs, this is the specific personality module required.
