Emerson Ovation 1C31234G01 Contact Input Module

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

Automation System, specifically designed for industrial discrete signal acquisition. 1C31234G01 is a 

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

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

supply configuration.

1C31234G01 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.

1C31234G01 is optimized for compact design, making 1C31234G01 ideal for space-constrained 

control cabinet environments. 1C31234G01 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, which enables 

real-time monitoring of device status and execution of control logic in industrial processes.

1C31234G01 has a robust industrial-grade design, adhering to the Ovation® system’s high reliability 

standards to ensure stable operation in harsh industrial environments. 1C31234G01 seamlessly 

integrates with the Ovation® process automation ecosystem, making 1C31234G01 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.
