OVATION 1C31129G04 – Product Profile
OVERVIEW
The OVATION 1C31129G04 is a high-precision analog output module designed for industrial process automation systems. It converts digital control signals from a distributed control system (DCS) into 0–20 mA current signals, which are commonly used to drive actuators, control valves, and other field devices. This module is engineered for reliability, stability, and precision, suitable for harsh industrial environments.
PRODUCT DESCRIPTION
The 1C31129G04 features multiple analog output channels with 16-bit resolution, providing highly accurate signal conversion. Unlike voltage output modules, it delivers current outputs, making it suitable for long-distance transmission with minimal signal loss. The module is modular and plugs directly into the backplane of the Ovation I/O rack, allowing easy integration, maintenance, and expansion. LED indicators per channel provide operational status and diagnostic feedback, ensuring smooth system operation.
