Functional Devices RIBMU2C Relay

The Functional Devices RIBMU2C is a high-reliability, track-mounted pilot relay designed for versatile control in building automation and HVACR systems. This 2 SPDT relay features independent continuous duty coils that support a wide range of input signals, specifically 10-30 Vac/dc or 120 Vac, allowing for seamless integration with both low-voltage controllers and line-voltage circuits. Built for high-density panel applications, the RIBMU2C relay snaps directly into a standard 4-inch mounting track, providing a clean and organized installation for multi-load switching environments. With its 15 Amp resistive contact rating and LED status indicators, this unit ensures reliable switching of inductive, resistive, and motor loads up to 1/3 HP. Whether you are configuring logical AND/OR control circuits or isolating sensitive BAS controllers from high-voltage field devices, the Functional Devices track mount relay offers the mechanical durability and electrical performance required by veteran field technicians and electrical contractors.

Key Benefits:

• Dual SPDT configuration: Two independent 15 Amp relays in a single 4-inch track-mount footprint for efficient panel space usage.
• Multi-voltage input: Compatible with 10-30 Vac/dc or 120 Vac control signals, reducing the need for multiple SKUs on the truck.
• Visual diagnostics: Onboard LED status indicators provide immediate confirmation of relay activation for faster troubleshooting.
• High switching capacity: Rated for 15 Amp resistive and 480 VA pilot duty, suitable for fan motors, lighting, and HVAC staging.
• Rugged mechanical life: Rated for a minimum of 10 million cycles, ensuring long-term stability in commercial building automation systems.

Common Questions:

Does the RIBMU2C require a specific mounting track?
Yes, this module is designed for standard 4-inch wide plastic snap-track (standard MT4 series), allowing you to mix and match different RIBM series modules within the same enclosure.

Can I use different voltages for each of the two relays?
The RIBMU2C contains two isolated relays. Each relay can be triggered by its own control voltage (either 10-30V or 120V) as long as you do not apply power to both the low-voltage and high-voltage coil inputs of a single relay simultaneously.

Is this relay suitable for motor loads?
Professionals typically use this for 1/3 HP @ 120-277 Vac (Normally Open) or 1/6 HP (Normally Closed) loads, making it ideal for standard blower and pump control applications.
