Functional Devices RIBU1SM-250 Switch
The Functional Devices RIBU1SM-250 is a specialized enclosed pilot relay featuring a Carling rocker switch for manual override control. This SPDT relay is engineered for industrial and commercial HVACR applications where local ON-AUTO-OFF manual override is required for troubleshooting or maintenance. The unit is housed in a NEMA 1 rated enclosure, pre-wired with 16-inch leads to streamline field installation into any standard 1/2-inch conduit knockout. With a wide coil voltage range of 24Vac/dc or 120Vac, it provides exceptional versatility for integrating BAS controllers with line-voltage loads. The heavy-duty 10 Amp contacts are rated for 277Vac, making this unit a reliable solution for switching lighting circuits, fractional horsepower motors, and fan coils. The integrated LED status indicator provides immediate visual confirmation of the relay coil's energized state, reducing diagnostic time for field technicians.
Key Benefits for Technicians:- Manual Override Control: The high-quality Carling toggle switch allows for manual forcing of the load during commissioning or system failure.
- Flexible Coil Input: Dual-input 24V or 120V coil allows for inventory consolidation as one dry contact relay covers most common control voltages.
- Pre-Wired Sub-Assembly: Factory-installed 16" leads and a threaded 1/2" nipple ensure a clean, professional install without hunting for additional fittings.
- Durable Construction: The NEMA 1 enclosure protects the RIBU1SM-250 internal components from dust and physical damage in mechanical rooms.
- Local Status Monitoring: Visual LED feedback confirms the control signal is reaching the coil, simplifying circuit tracing.
What is the maximum contact rating for motor loads?
The relay is rated for 1/2 HP at 120Vac and 3/4 HP at 240-277Vac, making it suitable for larger exhaust fans and small compressor signals.
Can the manual switch bypass the BAS signal?
Yes, the three-position Carling switch allows you to manually force the load 'ON' or 'OFF' regardless of the controller's logic, which is critical during system balance or sensor failure.
How is the unit mounted to a junction box?
The hardware includes a standard 1/2" NPT hub. It is designed to be mounted externally to any electrical box or control panel via a standard knockout.
