Emerson Ovation 1C31234G01 Contact Input Module

The 1C31234G01 is a compact contact input module belonging to Emerson’s Ovation® Process 

Automation System, specifically designed for industrial discrete signal acquisition. As a key 

component of the system’s I/O module family, it features 16 independent contact input channels, 

integrated with onboard 48 V DC wetting functionality to simplify field wiring and device power 

supply configuration.

This module is engineered to work with a dedicated Cavity Insert 2 (part number 1C31238H01) 

instead of a traditional personality module. The cavity insert fits into the personality module slot, 

providing clear wiring schematic labels for straightforward installation and maintenance without 

requiring additional functional configuration modules.

Optimized for compact design, the 1C31234G01 is ideal for space-constrained control cabinet 

environments. It specializes in receiving contact signals from industrial field devices such as limit 

switches, pushbuttons, and proximity sensors, converting these discrete signals into digital data 

compatible with the Ovation® system’s central control unit. This enables real-time monitoring of 

device status and execution of control logic in industrial processes.

With robust industrial-grade design, the module adheres to the Ovation® system’s high reliability 

standards, ensuring stable operation in harsh industrial environments. It seamlessly integrates with 

the Ovation® process automation ecosystem, making it suitable for critical control scenarios in 

industries such as power generation, oil and gas, and chemical processing—delivering accurate and 

responsive discrete input signal processing to support safe and efficient operation of industrial 

systems.

System Compatibility: Fully integrated with Emerson’s Ovation® Process Automation System, 

compliant with the system’s I/O communication protocol and hardware architecture for seamless 

data exchange with the central control unit.

Configuration Component: Paired exclusively with Cavity Insert 2 (part number 1C31238H01) – a 

labeling-oriented insert that fits into the personality module slot, providing clear wiring schematic 

guidance without requiring additional functional configuration modules. No traditional personality 

module is needed for operation.
