Overview
The Opto 22 IAC5Q is a quad pak 4-channel AC/DC input module designed for sensing ON/OFF voltage levels in industrial control systems. This lot of 2 provides redundancy or simultaneous deployment in multiple PLC applications. Each module accepts input voltage of 90-140 VAC/VDC and operates with 5 VDC logic levels, making it compatible with standard Opto 22 I/O architectures and third-party controllers.
