Securitron RB-4 Relay Board in 12VDC or 24VDC

The Securitron RB-4-24 Relay Board is a professional-grade solution designed to enhance the signaling and control capabilities of any access control system. This versatile board features four DPDT relays that provide normally-open or normally-closed dry contacts, making it the industry-standard choice for interlock installations, airlocks, and mantraps. Whether you need to shunt alarm contacts, trigger high-current actions, or provide remote status reporting, the RB-4-24 offers the precision and reliability required for higher-security environments.

Engineered for seamless integration, the Securitron RB-4-24 operates with extremely low current coils (only 8mA at 24VDC), allowing it to be triggered directly from most LED drive outputs without overtaxing your controller. Its compact design features screw terminals for secure, long-term wiring and is intended to replace bulky, less reliable socket-mount relays. Backed by the renowned MagnaCare® lifetime replacement warranty, this relay board ensures your security system’s logic remains robust and maintenance-free.
