SSU-MR-104/T SPACE AGE

Product Overview

The Space Age Electronics SSU-MR-104/T is a track-mounted, 4-position (quad) multi-voltage SPDT control relay assembly designed for seamless integration inside centralized system control cabinets and custom power panels. Engineered to handle high-density signal distribution, HVAC fan shutdowns, elevator recalls, and complex interlocking load controls, this unit comes pre-mounted on a shared circuit assembly. Its specialized "snap-apart" construction allows installers to physically break the master board down into smaller independent segments (such as single, dual, or triple relay setups) to fit custom spacing requirements. Each separate relay module can be snapped directly into standard 3.25-inch plastic mounting track channels. Polarized DC control inputs protect the inner circuitry, while high-visibility onboard red LEDs provide immediate visual confirmation of coil activation for each individual relay position.

Key Features

• 4-Position Master Relay Assembly: Consolidates four independent SPDT control relays onto a single track-mountable card assembly for high-density circuit management.
• Universal Multi-Voltage Inputs: Each independent relay module features dedicated terminal blocks that accept 18 to 35VDC, 18 to 35VAC, 120VAC, or 230VAC control signals.
• Continuous-Duty Operational Limits: Optimized for continuous-duty operation when driven by 24VDC, 24VAC, or 120VAC inputs (not intended for continuous-duty application at 230VAC).
• Form C Dry Resistive Contacts: Outfitted with robust single-pole double-throw contacts rated for 10A at 120VAC/30VDC, 7A at 230VAC, and 7A at 28VDC.
• Modular Snap-Apart Base: Features a multi-position substrate layout that can be manually snapped apart into smaller module groups depending on cabinet constraints.
• 3.25-Inch Snap Track Form Factor: Form-fitted for direct, tool-less slider installation into standard 3.25-inch wide plastic snap-track channels inside electrical backboxes.
