3RH2131-2SB40 SIEMENS

The 3RH2131-2SB40 is a coupling contactor relay manufactured by Siemens, designed for switching auxiliary circuits and control signals in industrial applications. This relay features a contact configuration of 3 normally open (NO) and 1 normally closed (NC) contacts, providing versatile switching options. It operates on a 24 V DC control voltage, with a wide operating range of 0.85 to 1.85 times the rated voltage (US), ensuring reliable performance even with voltage fluctuations. An integrated suppressor diode protects the relay coil and connected circuits from voltage spikes during switching. The relay is size S00, a compact design suitable for space-saving installations in control panels and enclosures. It utilizes spring-type terminals for quick, secure, and vibration-resistant connections, simplifying wiring and maintenance. This coupling contactor relay is ideal for isolating control circuits, amplifying signals, and interfacing between different voltage levels. Its robust construction and reliable performance make it suitable for various industrial automation and control applications. Siemens is a trusted brand known for high-quality and durable industrial components.
