Overview
The Opto22 OAC5Q is a 4-channel AC digital output module designed for industrial automation and control applications. This Quad Pak module is engineered to reliably control or switch AC loads ranging from 12 to 280 VAC, making it suitable for a wide variety of industrial equipment and systems. The module operates with a 5 VDC logic level and is housed in a compact Quad Pak format that integrates the equivalent of four single-channel I/O circuits into a single package.
Key Features
- 4-channel AC output capability for controlling loads up to 280 VAC
- Quad Pak design with two independently controllable pairs, each sharing a common connection
- 5 VDC logic level operation for safe, isolated control
- 4000 V (RMS) optical isolation between field devices and control logic
- Mounts directly into Quad Pak I/O mounting racks only (not compatible with single-channel or SNAP racks)
- Compatible with Optomux, Pamux, and Mistic protocol brain boards and mounting racks
