The Space Age SSU-MR-204/C is a four-position DPDT multi-voltage control relay assembly. It houses four independent DPDT relay modules in a grey enclosure. Each module switches two circuits for fire alarm and building control systems. As a result, one unit delivers dense, flexible switching capacity.
Space Age SSU-MR-204/C relay features
Every position contains a red LED. This LED lights when the relay coil is energized. Therefore, technicians can verify each relay without metering. In addition, the modules snap apart from the four-position master and work independently.
Each module accepts one of four control voltages. Specifically, you can wire it for 24VDC, 24VAC, 120VAC, or 230VAC. The DC coil operates from 18 to 35VDC. Also, the DC inputs are polarized.

Applications
This assembly suits larger fire alarm and building control jobs. For example, it can sequence HVAC, lighting, and notification circuits. However, do not run it continuously at 230VAC. Continuous duty applies at 24VAC, 24VDC, and 120VAC.
