Overview
The Emerson 1C31122G02 is a 16-channel digital output module designed for Ovation distributed control systems (DCS). It provides discrete signal switching between the control system and connected field devices. The module supports 5-60 VDC output signals, with a rated current of 0.5 A per channel and a maximum aggregate current of 8 A.
Output Configuration and Signal Control
The module provides 16 digital output channels for controlling external devices through discrete electrical signals. Each channel supports an output current of up to 0.5 A, while the total output current across all channels must remain within the specified 8 A limit.
Furthermore, the specified channel-to-channel isolation is 500 VDC. This electrical separation helps limit direct signal coupling between individual output channels. The stated response time is less than 1 ms, making the module suitable for applications requiring rapid digital output switching.
