SSU-MR-101/C/R SPACE AGE

Product Overview

The Space Age Electronics SSU-MR-101/C/R is a single-position, multi-voltage SPDT control relay housed inside a protective, high-impact red ABS 94V-0 plastic enclosure. Primarily specified to meet municipal building mandates requiring highly identifiable red emergency casings, this versatile relay provides a reliable method for local signal routing, HVAC fan shutdowns, elevator recall triggers, and auxiliary load control. 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 requiring meter diagnostics.

Key Features

• Multi-Voltage Coil Input Matrix: Accepts flexible control circuit voltages including 18 to 35VDC, 18 to 35VAC, 120VAC, and 230VAC for versatile field deployment.
• Continuous-Duty Limitations: Specifically engineered for continuous-duty cycles when driven by 24VDC, 24VAC, or 120VAC inputs (not intended for continuous duty at 230VAC).
• Form C Dry Resistive Contacts: Equipped with a single set of SPDT contacts rated for 10A at 120VAC/30VDC, 7A at 230VAC, and 7A at 28VDC.
• Red ABS 94V-0 Housing: Enclosed in a flame-retardant red plastic cover optimized for high visibility and adherence to specific local building emergency codes.
• Time-Saving Visual Indicator: Features an onboard red LED status tracker that lights up instantly when the coil shifts, speeding up system loop verification tasks.
• Polarized Input Protection: Incorporates polarized DC control terminals to eliminate potential circuit damage resulting from reverse-wiring mistakes in the field.
• Life Safety Approvals: Fabricated under rigid quality parameters, earning full UL listing as a Control Unit Accessory alongside UUKL Smoke Control compliance.
