SSU-MR-701/C SPACE AGE

Product Overview

The Space Age Electronics SSU-MR-701/C is a single-position, dual-voltage SPDT control relay housed inside a protective gray cabinet enclosure. Engineered for reliable, low-voltage DC switching in fire alarm networks, security control access systems, and building automation lines, this module can be energized by mapping field connections to either a 12VDC or 24VDC control terminal. The DC control inputs are fully polarized to prevent damage from reverse wiring, and the main circuit board includes a high-visibility onboard red LED that illuminates automatically whenever the relay coil is energized. This provides field technicians with rapid visual verification during system commissioning without requiring digital diagnostic multi-meters.

Key Features

• Dual-Voltage DC Input: Accepts polarized 12VDC or 24VDC control circuit inputs for precise low-voltage equipment interfacing.
• Form C Dry Contacts: Outfitted with a single set of SPDT resistive contacts rated for 10A at 120VAC, 7A at 230VAC, and 7A at 28VDC.
• Modular Breakaway Design: Substrate features a snap-apart layout, allowing it to be physically separated from multi-position assemblies if needed.
• 18-Gauge Steel Gray Cabinet: Encased in a durable cold-rolled steel backbox featuring individual ABS plastic viewing windows to easily monitor internal diagnostics.
• Visual Status Tracker: Built with an onboard red LED indicator that lights up instantly when the coil shifts to streamline troubleshooting.
• Reverse Polarity Protection: Incorporates polarized DC control terminals to protect the internal microcircuitry against field cross-wiring errors.
• Life Safety Compliance: Formally evaluated and listed under UL Control Unit Accessories alongside strict UUKL Smoke Control system criteria.
