SAE SSU-MR-104/C/R MR-100 Series Multi-Voltage Control Relay, 10A, 24VDC/24VAC/120VAC/230VAC, SPDT, Red

Optimize control and reduce parts complexity with the Space Age Electronics MR-100 Series Multi-Voltage Control Relay — a versatile enclosure-mount relay built for security, surveillance, HVAC and building monitoring applications. The MR-100 accepts multiple input voltages (24VDC, 24VAC, 120VAC or 230VAC), so a single relay model covers a wide range of control panels and field devices. Its SPDT resistive contacts are rated to 10A for dependable switching of lighting, fans, dampers and other control loads, while the integrated red LED per position provides instant coil-status feedback to speed troubleshooting.

Designed for contractors and systems integrators, the modular snap-apart construction lets you use single, dual or multi-position modules to match enclosure space and reduce waste. Continuous-duty operation and enclosure mounting ensure long-term reliability in fire alarm, energy management and temperature control systems. Ideal for streamlining installations in security, surveillance and monitoring projects, the MR-100 reduces wiring complexity and improves on-site diagnostics.
