Product description

The Siemens 7PU2040-7AN20 is a solid-state time delay relay designed for surface mounting. It features an ON-delay function with one changeover (CO) contact. The time setting range is adjustable from 2 seconds to 20 seconds, and it operates on AC voltages of 220-240V at 50/60Hz.

This relay is used in control circuits to introduce a time delay between the energization of the coil and the actuation of the output contact. It is commonly applied in motor starting sequences, timed control processes, and safety circuits where a specific delay is required before a function can operate.

Stanlo Automation, a veteran-owned surplus distributor, provides reliable Siemens industrial components, including time relays like the 7PU2040-7AN20. Source your essential control components from Stanlo for quality and value.
