The 70M-IAC5A is a digital AC input module designed to provide optically isolated barrier between sensitive microprocessor circuits and field AC power devices. This Mini package module operates with a logic supply voltage of 5 Vdc and accepts AC input signals at 120 Vac, making it suitable for standard industrial AC signal detection applications. The module features a solvent-resistant thermoplastic case meeting UL94-V-0 rating, tin-plated copper wire terminal pins, and surface mount construction for low operating junction temperatures and extended operational life. It includes a green status LED for module identification and is backed by a lifetime warranty. The 70M-IAC5A is ideal for applications requiring flexible mixing and matching of analog and digital I/O modules on the same mounting rack, particularly in data acquisition, monitoring, and control systems that interface with various AC sensors and loads.
