The 7022OD is an industrial electropneumatic off-delay timing relay designed for applications requiring delayed contact switching upon de-energization. The unit features adjustable timing from 0.1 seconds to 60 minutes in linear increments, with repeat accuracy of ±5% for delays up to 200 seconds and ±10% for longer delays. It operates over a coil voltage range of 6–550 VAC and 12–550 VDC, with standard 2-pole or 4-pole contact configurations available. The relay provides inherent transient immunity and includes oversize time-calibrated adjustment knobs with high-resolution markings for easy field adjustment. Common applications include industrial control systems, process automation, and equipment protection circuits where delayed response to de-energization is required.
