Emerson 1C31132G01 | Special Analog Output Personality Module
Product Introduction
1C31132G01 is Emerson Ovation dedicated 4-channel analog output personality module originated from Westinghouse design, which must be matched with base unit 1C31122G01 for Ovation remote I/O rack installation. It converts digital bus commands from Ovation controller into standard industrial analog signals to drive field control valves, dampers and VFD actuators, widely used as critical spare part for thermal power and petrochemical DCS closed-loop regulation system.
Description
Part Code Definition
1C31xxx: Standard Ovation remote I/O personality module series132: Model code for 4-channel configurable analog output cardG01: Fixed hardware revision version
Technical Specifications

Interface & Communication Layout
Rear card edge connects base module 1C31122G01 to realize system backplane bus data transmission;Front terminal block for field actuator analog signal wiring;Front panel LED indicators including RUN running light, module fault alarm and independent channel status display.
Core Functions
Digital-to-analog conversion to fulfill continuous closed-loop process control;Independent over-current & short-circuit protection per channel, single-channel fault causes no influence to remaining channels;Built-in hardware self-diagnosis for open-loop, overload and internal circuit failure, fault information auto uploaded to Ovation host controller;Output signal range configurable via Ovation system configuration software.
Application Scenarios
Boiler feedwater valve modulation, furnace air damper adjustment, turbine auxiliary loop control in thermal power plants; flow/pressure closed-loop regulating cabinet spare replacement and system expansion for petrochemical refining DCS projects.
Operation & Maintenance Notes
Adopt shielded twisted-pair cable for AO field wiring with single-end shield grounding inside control cabinet;Separate analog signal cables from high-power AC power cables to eliminate EMI interference;Check terminal fastening tightness and output accuracy during regular equipment maintenance; replace built-in small fuse once channel overload happens.
