OPTO 22 G4IAC5L Digital AC Input Module

The G4IAC5-L digital AC input module detects AC or DC voltage presence with up to 4000V optical isolation, ensuring transient suppression and noise immunity. Its filtering and hysteresis amplifier enable reliable, transient-free switching for sensing voltage or contact closures from proximity, limit, float, or toggle switches, and thermostats. Features include a built-in LED indicator, compact design, UL, CSA, and CE approvals, NEMA arc testing compliance, IEEE surge standards, and quick 20ms turn-on/off times. Ideal for industrial automation and control applications requiring high transient immunity and reliable switch detection.
