Functional Devices-RIB RIBU1SC Relay

The Functional Devices RIBU1SC is a heavy-duty enclosed pilot relay designed for seamless integration into industrial control systems and building automation. This 10 Amp SPDT relay is engineered with a multi-voltage input capability, accepting 10-30 Vac/dc or 120 Vac, which simplifies inventory by replacing multiple single-voltage components. A critical feature for field technicians is the manual override switch, which allows for direct control of the load during commissioning or system diagnostics. This pre-packaged relay is housed in a NEMA 1 rated enclosure, ensuring protection for internal components while facilitating quick mounting to standard electrical boxes via the 1/2-inch NPT nipple. The dry contact relay configuration is rated for resistive, inductive, and motor loads, making it an ideal choice for switching HVAC control circuits, exhaust fans, and lighting loads. With its gold flash contacts and LED status indicator, the RIBU1SC provides high-reliability switching and immediate visual feedback for troubleshooting in the field.

• Dual-coil input supports 24V or 120V applications for maximum site flexibility.
• 3-position override switch (On/Auto/Off) enables manual load testing without a controller signal.
• Space-saving design fits inside standard junction boxes or mounts externally to save panel space.
• Pre-wired color-coded leads reduce installation time and prevent wiring errors.
• LED status indicator provides instant verification of coil Phil power and relay state.

Can the manual override switch be used to bypass a failed controller?
Yes, the manual switch allows a technician to force the contactor into a closed or open state regardless of the signal coming from the automation system.

What is the maximum horsepower rating for this relay?
The RIBU1SC is rated for motor loads up to 1/3 HP at 120 Vac, making it suitable for small fan motors and dampers.

Is the enclosure rated for outdoor use?
This specific model features a NEMA 1 enclosure intended for indoor applications. For rooftop or outdoor installs, a NEMA 4 or 4X rated RIB model should be utilized.
