Westinghouse 1C31161G02 Ovation Analog Input Module - RTD

Product Description

Configured for RTD temperature signal acquisition in Ovation Distributed Control System hardware, the Emerson / Westinghouse 1C31161G02 (1C31161G02 Analog Input Module) provides direct physical and electrical signal processing. The module receives resistance-based temperature inputs from connected RTD sensors and converts the measured values into data for the Ovation control system. Its specified resolution is 0.01 deg C, while accuracy is rated at +/- 0.5% full scale.

Hardware Specifications

RTD Signal Processing and DCS Integration

The Emerson / Westinghouse 1C31161G02 processes resistance-based RTD input signals at the field interface. RTD sensors change electrical resistance as temperature changes, and the module acquires this input for use by the Ovation control architecture.

In addition, the module operates from a 24 VDC supply with a maximum specified power consumption of 1.2 W. Installation should therefore maintain correct supply polarity and use suitable industrial control wiring practices. Signal cables should also be routed separately from high-power conductors to reduce electrical interference.

Frequently Asked Questions

Q: What type of field sensor does the 1C31161G02 support?
A: The 1C31161G02 is specified as an Analog Input Module for RTD inputs and is designed to acquire resistance-based temperature signals.

Q: What power supply is specified for the 1C31161G02?
A: The module operates at 24 VDC and has a maximum specified power consumption of 1.2 W.

Q: What is the specified temperature input resolution?
A: The specified input resolution is 0.01 deg C, with an accuracy of +/- 0.5% full scale.

Field Installation Guidelines

Mount the Emerson / Westinghouse 1C31161G02 in the applicable Ovation hardware assembly according to the system installation documentation. Ensure that the module is fully seated before applying system power.

Use wiring suitable for RTD measurement circuits and keep temperature signal conductors separated from motor, relay, and other high-current wiring. Where shielded cable is required by the installation design, terminate the cable shield according to the site grounding practice to avoid ground-loop interference.

Verify RTD wiring continuity and terminal assignments before energizing the circuit. In addition, confirm the 24 VDC supply polarity and inspect all field connections for loose terminals or damaged insulation.
