Digital output module GRV-OACS-12

12-OEPICautomation

Overview

The GRV-OACS-12 is a groov EPIC® digital AC discrete output module providing 12 on/off channels for switching AC loads from 12 to 250 VAC. Designed for straightforward on/off applications, it features transient protection and zero-voltage switching to reduce switching transients.

Compatibility and operation

The module mounts on a groov EPIC chassis with a GRV-EPIC-PR1 processor. The cover includes an LED status indicator and a touch-sensitive pad that prompts the groov EPIC processor to display module information, specifications, and a wiring diagram.
