3RP2540-2BB30 SIEMENS

The 3RP2540-2BB30 is an electronic timing relay from Siemens, designed for OFF delay applications without requiring a control signal. This relay features a smooth passing make contact and non-volatile memory, ensuring reliable operation even in the event of power loss. It offers seven selectable time ranges, spanning from 0.05 seconds to 600 seconds, providing flexibility for various timing requirements. The relay operates on a 24 V AC/DC power supply and is equipped with two change-over contacts, each with a clear LED indicator for visual status monitoring. Connection is simplified through spring-type terminals (push-in), allowing for quick and secure wiring. Its primary function is to delay the de-energization of a circuit after the input signal is removed. This makes it suitable for applications such as controlling ventilation systems, lubrication systems, or emergency lighting. The non-volatile memory ensures that the set time delay is retained even after a power interruption. This timing relay provides precise and dependable time-delayed switching for a wide range of industrial automation applications.
