SSU-MR-201/C/R SPACE AGE

Product Overview

The Space Age Electronics SSU-MR-201/C/R is a single-position, multi-voltage DPDT control relay housed inside a high-visibility, flame-retardant red ABS plastic enclosure. Engineered to meet municipal regulations requiring highly identifiable red casings, this versatile module handles high-density signal distribution, HVAC damper controls, and elevator recalls. The card can be energized by mapping field connections to one of four independent control voltage terminals: 24VDC, 24VAC, 120VAC, or 230VAC. Polarity-protected DC inputs safeguard the internal microcircuitry, while a bright, built-in red diagnostic LED shines through the cover window to confirm that the internal coil is successfully energized without opening the assembly.

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 inputs including 24VDC, 24VAC, 120VAC, and 230VAC terminal landing points.
• Continuous-Duty Limitations: Optimized for continuous-duty cycles when driven by 24VDC, 24VAC, or 120VAC inputs (not intended for continuous duty at 230VAC).
• Red ABS 94V-0 Housing: Enclosed in a flame-retardant red plastic cover optimized for high visibility and adherence to local emergency codes.
• Time-Saving Visual Tracker: Outfitted with an internal red LED indicator that lights up instantly when the coil shifts to speed up loop validation.
• Polarized Input Protection: Incorporates polarized DC control terminals to eliminate circuit damage from field reverse-wiring mistakes.
• Smoke Control Listing: Formally evaluated and listed under UL Control Unit Accessories alongside strict UUKL Smoke Control system standards.
