Product description

The Siemens 7PV1540-1AW30 is an electronic timing relay designed for OFF delay applications without requiring an external control signal. It features 7 selectable time ranges from 0.05 seconds up to 100 seconds, operating on a voltage of 12-240V AC/DC. This model includes a single change-over (C/O) contact and an integrated LED for operational status indication. The relay is equipped with screw terminals for straightforward wiring.

This timing relay is ideal for applications where a timed delay after power removal is needed, such as in motor control circuits, fan control, or temporary power sequencing. Its fixed time range makes it suitable for straightforward, repeatable timing tasks in various industrial settings.
