SSU-MR-204/T SPACE AGE

Product Overview

The Space Age Electronics SSU-MR-204/T is a track-mounted, 4-position (quad) multi-voltage DPDT 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 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 completely independent DPDT control relays onto a single track-mountable card assembly.
• Universal Multi-Voltage Inputs: Each relay segment incorporates field terminals designed to accept 24VDC, 24VAC, 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 use at 230VAC).
• High-Density DPDT Contact Sets: Outfitted with robust dual-pole double-throw dry Form C contacts rated for 10A at 120VAC or 7A at 230VAC/28VDC.
• Modular Snap-Apart Board: Circuit substrate features built-in score lines to let field technicians snap individual relay sections off the master matrix.
• 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.
• Polarized Input Protection: Employs fully polarized DC control inputs to safeguard components against damage from accidental reverse field wiring.
