Ovation 1C31174G03 | Loop Interface Module 30-Day Returns

Overview

The Ovation 1C31174G03 is a loop-interface module for the Ovation Distributed Control System (DCS). It provides the analog 4–20 mA loop interface, enabling field transmitters and sensors to connect reliably to the DCS, with proper signal conditioning and isolation.

General Information

Part Number: 1C31174G03
Manufacturer: Emerson / Ovation (Westinghouse legacy)
Series: Ovation Loop-I/O Modules
Type: Loop Interface Module (Analog 4–20 mA I/O + Digital I/O)
Mounting: Rack or chassis-mounted inside Ovation I/O cabinet, connected via backplane bus
Function: Accepts 4–20 mA field loops, converts/isolate signals, interfaces to Ovation system logic for monitoring and control

Signal & Interface Specifications

Analog Input / Output: Supports 4–20 mA input and 4–20 mA output loops
Digital I/O: Supports standard DCS digital input and output levels (e.g. 24/48 V DC inputs, 60 V DC outputs)
Signal Conditioning: Provides isolation and signal conditioning for analog loops to ensure stable readings and protect DCS from field noise
Compatibility: Works with standard Ovation backplane and I/O architecture, and can integrate with “personality modules” (for e.g. grounding/shielding, remote-powered loops)

Environmental & Operational Conditions

Operating Temperature: Industrial control-cabinet standard range
Humidity: Supports non-condensing humidity under normal control-room conditions
Installation Environment: Must be installed inside enclosed control cabinet or protected rack (not exposed to field ambient directly)

Dimensions & Weight

Dimensions (L × W × H):  300 × 200 × 50 mm
Weight:  3.0 kg
