120 VAC Input Module for SSR—The SSR‑IAC5 senses voltage from a field source and converts AC voltage to a TTL logic signal. The SSR‑IAC5 is fully encapsulated and plugs into an 8‑, 16‑, 24‑, or 32‑slot backplane or a shielded carrier. Field signals connect to screw terminals on the backplane, making it easy to swap or replace modules. You can use the SSR‑IAC5 to monitor the state of a load or a sensor, such as a temperature switch or limit switch.
