Emerson 1C31219G01 high-performance analog input module

Description

The Emerson 1C31219G01 is a 16-channel relay output module designed for use within the Emerson Ovation Distributed Control System (DCS). It is widely used in industrial automation environments where discrete output signals are needed to control equipment such as valves, motors, and alarms. This module excels in applications requiring reliable on/off switching capabilities under harsh industrial conditions, making it suitable for power generation plants, water treatment facilities, petrochemical processing, and manufacturing automation.

The 1C31219G01 provides a robust interface between the Ovation control system and field actuators, enabling logic-based control of relay devices. Each channel can switch loads up to 5 amperes at 120 VAC, making it suitable for a wide range of industrial electrical loads. Its design emphasizes electrical isolation and fault tolerance, contributing to system safety and uptime.

Functionally, the Emerson 1C31219G01 acts as a relay output card that switches relay coils or other discrete devices based on control system commands. The module supports 16 independent relay outputs, each capable of handling industrial-level currents and voltages. Its mechanical relay design ensures positive switching actions, essential for safety and fail-safe applications.

The module features diagnostic LEDs for each channel, providing quick visual indications of output status and potential faults. It also includes built-in surge protection and noise filtering to safeguard sensitive control electronics from electrical disturbances common in industrial settings. Easy integration with the Ovation system allows seamless replacement or upgrade without complex reconfiguration.

Technically, the 1C31219G01 supports switching of loads rated up to 5A at 120 VAC per channel. The module operates on a nominal 24 VDC power supply and features 1500 V galvanic isolation between output channels and logic circuits, ensuring electrical safety and noise immunity. Designed for operation in industrial environments, it supports operating temperatures from 0°C to 60°C and can withstand non-condensing humidity up to 95%.

The module typically weighs around 3 kilograms and fits within standard rack-mount or chassis-based system architectures. It is constructed to meet rigorous industrial standards for reliability, robustness, and safety, supporting long-term use in critical process control applications.
