SSU-MR-201/C SPACE AGE

Product Overview

The Space Age Electronics SSU-MR-201/C is a single-position, multi-voltage DPDT control relay housed inside a protective gray enclosure. Designed for high-density signal handling, HVAC damper controls, fire alarm networking, and lighting management systems, this versatile relay module can be energized by mapping field connections to one of four independent control voltage terminals: 24VDC, 24VAC, 120VAC, or 230VAC. The DC control inputs are fully polarized to safeguard the internal microcircuitry against accidental reverse wiring. Additionally, a prominent onboard red diagnostic LED illuminates automatically whenever the internal coil is successfully energized, providing quick visual verification during field system commissioning.

Key Features

• High-Density DPDT Switching: Features dual-pole double-throw dry Form C contacts rated for 10A at 120VAC and 7A at 230VAC or 28VDC.
• Multi-Voltage Input Matrix: Accepts versatile field control circuit inputs including 24VDC, 24VAC, 120VAC, and 230VAC terminal landing points.
• Continuous-Duty Limitations: Specifically engineered for continuous-duty operation when driven by 24VDC, 24VAC, or 120VAC inputs (not intended for continuous duty at 230VAC).
• Modular Snap-Apart Fabrication: Circuit substrate features a snap-apart construction allowing it to be physically broken down from a 4-position master configuration if needed.
• Durable Industrial Housing: Enclosed in a dust-resistant, 18-gauge cold-rolled steel gray backbox featuring integrated 1/2-inch conduit knockouts.
• Time-Saving Status Tracker: Outfitted with an internal red LED indicator that lights up instantly when the coil shifts, removing the need for meter troubleshooting.
• Smoke Control Listing: Formally evaluated and listed under UL Control Unit Accessories alongside strict UUKL Smoke Control system standards.
