The Tesch PL125 Timer is an electromechanical time relay that provides adjustable time-delay switching for industrial control circuits. It operates at 220 VAC, 50 Hz, with a front-mounted potentiometer for precise time setting and a panel-mount housing using relay output contacts. The timing range is adjustable depending on configuration, making it suitable for process sequencing, delayed motor starting, and automated switching in control panels, conveyors, manufacturing equipment, and machine control circuits. Common replacements include the Tesch VS Timer and the E74 and E75 series time delay relays.
