Product description

The Siemens 7PU1540-8AB30 is a solid-state time relay designed for surface mounting. It features an off-delay function with one delayed changeover contact. The time setting range is adjustable from 1.5 to 15 seconds. This relay operates on both AC (50/60Hz) and DC power supplies at 24V. It is designed for reliable and precise timing in control circuits and does not include provisions for remote control.

This time relay is commonly used in automation systems for sequencing operations, controlling delays in motor starting, conveyor belt systems, or any application where a timed delay is required after a signal is removed. Its solid-state design ensures long operational life and consistent performance across various industrial applications.

Stanlo Automation, a veteran-owned surplus parts distributor, offers the Siemens 7PU1540-8AB30. We provide access to high-quality industrial automation components, including essential control devices like this time relay, ensuring your automation projects are completed efficiently and reliably.

Frequently asked questions

What type of contact does the Siemens 7PU1540-8AB30 time relay have?

The Siemens 7PU1540-8AB30 features one delayed changeover (SPDT) contact. This means it can switch between two circuits after the set delay time has elapsed, with the initial state being determined by the energization or de-energization of the relay coil.
