Product information
SSU-MR-828/T
Overview
Built for reliable, high-density switching in security, surveillance and building automation systems, the Space Age Electronics MR-820 relay track (SSU-MR-828/T) delivers dependable SPDT control where space and uptime matter. Each relay position contains two independent, UL-recognized relays and a bright red LED that provides immediate visual confirmation of an energized coil — speeding troubleshooting for service technicians and reducing downtime for monitoring and alarm systems. Operating on 24VDC with a maximum input current of 2A, the MR-820 supports HVAC, fire alarm, energy management and access control integrations that require robust, low-voltage switching.
The modular snap-apart design lets you scale relay counts quickly, while the /T track mounting hardware simplifies installation in standard cabinets (an /S spacer option is available for back-panel mounting). These features make the MR-820 an excellent choice for installers and system integrators looking to optimize cabinet space and streamline wiring in surveillance and security control panels. For dependable relay performance in critical monitoring and fire/security applications, choose the Space Age Electronics MR-820 — contact your distributor to order or specify it on your next project.
