Functional Devices RIBU2C-AND Enclosed Pilot Relay 10A 2 SPDT 10-30 VAC/DC 120 VAC Coil

The Functional Devices RIBU2C-AND is a dual enclosed pilot relay from the RIB (Relay in a Box) series, designed for building automation, HVAC, and control system applications. It features two independent, isolated SPDT relays in a single NEMA 1 housing, making it ideal for logical AND or OR control wiring configurations.

Key Features:

• Dual relay design: Two (2) SPDT continuous duty relays in one compact enclosure — functionally equivalent to two RIBU1C units in a single housing
• Wide coil voltage range: Accepts 10–30 VAC/DC or 120 VAC, allowing compatibility with both low-voltage BAS/HVAC control signals and line voltage inputs
• 10 Amp contact rating: Rated for 10A resistive at 277 VAC and 10A resistive at 28 VDC; pilot duty rated at 277 VAC
• LED status indicator: Illuminates when relay is activated for quick visual confirmation
• Gold flash contacts: Enhances reliability on low-current pilot duty circuits
• Pre-wired and enclosed: Relay comes mounted and pre-wired in housing — no separate socket, rail, or enclosure assembly required
• Color-coded wires: 16-inch, 600V-rated leads with color coding to reduce installation errors
• 0.75 in. NPT nipple: All wires exit from a single conduit nipple for clean panel or equipment installation
• 10-year warranty
