Siemens 3RP2525-1BB30 Time Relay

Siemens Sirius 3RP2525-1BB30 Timing Relay is an electronic on-delay timer with two change-over contacts (DPDT) designed for 24 V AC/DC control circuits. It offers seven selectable time ranges spanning from 0.05 seconds to 100 hours, enabling precise short delays or long timing sequences for varied automation tasks. The device includes an LED indicator for status and uses screw terminals for reliable wiring. As part of the SIRIUS 3RP25 family, this relay delivers dependable timing control in panel installations, machine sequencing, and process automation where a defined delay after an input signal is required. The 3RP2525-1BB30 specifies the active 24 V DC or AC supply and a DPDT output configuration, enabling coordinated switching of two separate circuits or signals from a single timing operation. This timer is well-suited for start-up sequencing, delay-before-latching in control loops, or timed control of auxiliary devices in industrial automation.
