Agastat 7022PDT Time Delay Relay 120/240 VAC

The Agastat 7022PDT is an electropneumatic time delay relay designed for industrial applications requiring precise off-delay timing. Manufactured by Agastat (now part of TE Connectivity), this relay features a robust, adjustable timing mechanism that operates without relying on electronic components, making it highly reliable in harsh environments with high vibration, dust, or temperature variations. Key applications include process control, machine automation, conveyor systems, and motor control circuits where delayed de-energization is needed to ensure safe shutdowns or sequential operations. Advantages over electronic timers include superior resistance to electrical noise and longer service life in demanding conditions, though it may have drawbacks like larger size and mechanical wear over time compared to modern solid-state alternatives. The unit supports DPDT contacts for versatile switching, with an adjustable dial for setting delay times. It operates on 120/240 VAC and is UL-listed for safety. This model excels in legacy systems or where pneumatic reliability is preferred, offering repeatability within 5% and easy integration into control panels. Overall, it's a durable choice for industrial timing needs, balancing cost-effectiveness with proven performance.
