SYLVANIA 713UPDA-76 is an AC pneumatic timing relay (Joslyn Clark) designed to introduce a controlled time delay in industrial control circuits. It runs on a 120 V, 60 Hz AC supply and is part of the Joslyn Clark PMT family of pneumatic time-delay relays used in legacy equipment. The device provides a timed response to trigger or release circuitry after a preset interval, enabling sequencing and interlock functions in industrial controls. Common applications include timing in control panels and machinery where pneumatic timing relays are employed to coordinate startup or shutdown sequences.
