Functional Devices RIBU1C Enclosed Pilot Relay, 10 Amp, SPDT w/ 10 - 30 Vac/DC & 120 Vac Coil
An enclosed pilot relay used to switch a load through SPDT contacts from a low-voltage control signal in HVAC and general control applications.
Key Features:
- Enclosed pilot relay, SPDT (single-pole double-throw)
- 10 Amp relay
- With 10 - 30 Vac/DC and 120 Vac coil
Compatibility & Applications:
- Used as a control/isolation relay in HVAC and other low-voltage-to-load switching applications where an enclosed SPDT pilot relay is required
- Must only be used where the manufacturer specifies this exact part number: RIBU1C
Installation & Operation Notes:
- Installation should be performed by a qualified HVAC technician or electrician
- Reference the controlled equipment's service/installation manual and the relay's wiring/installation documentation for correct coil/control wiring and load wiring
- Verify load current requirements and wiring method before energizing the circuit (application suitability depends on the specific load and system design)
Maintenance & Troubleshooting:
- Relays are typically replaced when the controlled device will not energize/de-energize as expected or when the relay no longer switches reliably
- If operation is inconsistent after installation, verify correct control voltage to the coil, correct wiring to COM/NO/NC, and that the connected load is within the relay's intended use for that application (per the equipment documentation)
User Reviews & Q&A Summary:
- Reviews most often describe it as dependable and versatile for HVAC/control uses, including isolation relay setups and using low-voltage control to switch line-voltage devices.
- Common "why I bought it" themes include solving specific control problems (overflow/condensate alarm triggering, humidifier/thermostat interfacing, remote control of pumps/blowers/boiler-related loads), with most saying it "just works."
- Q&A themes emphasize application-specific sizing: it can be used for control tasks, but suitability depends on the load amperage and the need for an appropriate transformer/power source for the coil/control side (customers are directed to confirm their wiring plan and load details).
