120 VAC Output Module for SSR—The SSR‑OAC5 uses a logic TTL signal from a data acquisition device to switch AC and DC loads in a manner similar to conventional relays. If the data acquisition device is sending a logic low, the SSR‑OAC5 is turned on and current can flow. If the device sends a logic high, the SSR‑OAC5 is turned off and current is stopped. Unlike conventional relays, the SSR‑OAC5 has zero voltage turn on of the load. Also, a load voltage and minimum current must be present to maintain the SSR‑OAC5 in the on state.
