Opto 22 OAC5Q Quad Pak 4-Channel AC Output Module
The Opto 22 OAC5Q is a Quad Pak 4-channel AC output module designed to control or switch AC loads ranging from 12 to 280 VAC. Utilizing 5 VDC logic, this module is compatible with Opto 22’s Optomux, Pamux, and Mistic protocol brain boards and mounting racks, as well as systems connected directly to a computer. Additionally, it can be integrated with a Raspberry Pi using the Digital I/O Carrier Board (part number OPTO-P1-40P) and the PB16HQ mounting rack.
Key Features
- Quad Pak Design: Incorporates four single-channel I/O circuits within a single package, allowing division into two pairs, each sharing a common connection.
- High Voltage Range: Operates effectively within a voltage range of 12 to 280 VAC, accommodating various AC load requirements.
- Optical Isolation: Provides up to 4,000 Vrms of optical isolation between field devices and control logic, ensuring safe and interference-free operation.
- Zero Voltage Turn-On and Zero Current Turn-Off: Features zero voltage turn-on and zero current turn-off for efficient and reliable switching.
