Emerson 1C31122G01 Ovation 16-Channel Digital Output Module
The Emerson 1C31122G01 is a 16-channel digital output electronics module for the Ovation Distributed Control System (DCS). It provides current-sinking transistor outputs to drive discrete field devices such as relays, solenoids, indicator lamps, and contactors. Operating across a voltage range of 5 VDC to 60 VDC, it routes switching commands directly from Ovation controllers to plant actuators.
Channel Architecture and Output Ratings
The module features 16 solid-state transistor output channels, with each channel capable of switching up to 500 mA DC loads. Current-sinking configuration enables direct driving of DC field devices while isolating controller logic from field switching transients. Front-panel LED indicators display individual channel status, and configurable communication timeouts manage output states in the event of system network interruptions.
Hardware Installation and Enclosure Parameters
Designed as an electronics module (EMOD) for standard Ovation I/O module assemblies, the unit weighs 0.68 kg. It installs directly into designated Ovation base assemblies without requiring external interposing circuitry for compatible DC loads. The module is CE mark certified for industrial control system applications.
