Industrial 7380-0000 Relay from Action Pak Instruments uses a 120V AC coil to actuate its contacts in control circuits and instrumentation equipment. The specification lists a 0–5000 Hz range and a 0–5V DC input, with the WL5-3 designation noted in the product data, identifying the drive signal and control interface for this part. This item is identified by part number 7380-0000 and is listed by Action Pak Instruments as an industrial relay suitable for panel and automation environments. In practical terms, a relay provides electrical isolation between the control side and the load, allowing a low-voltage DC signal to switch higher-voltage AC circuits while protecting sensitive circuitry from surges and noise.
