Functional Devices RIB RIBM24S Relay

The Functional Devices RIBM24S is a professional-grade track mount power relay engineered for versatile BAS and HVAC controls applications. This 15 Amp SPST relay features a convenient Hands-Auto-Off override switch, allowing for manual system testing and troubleshooting without specialized tools. Packaged in a compact 4-inch track-compatible housing, the RIBM24S operates with a 24Vac/dc coil voltage, making it compatible with most low voltage control circuits. This unit is electrically identical to the FUN-RIBM2-4S and is built for high-duty cycle performance in demanding commercial environments. By utilizing a dry contact relay configuration with NEMA 1 rated characteristics, technicians can ensure reliable switching for fan motor controls and lighting loads. Its standard track-mount design simplifies rail installations in control panels, reducing labor time during field deployments. This enclosed relay provides essential isolation and protection for sensitive controller outputs against inductive kickback.

• SPST 15 Amp contacts provide robust switching capacity for heavy-duty HVAC and lighting applications.
• Integrated HOA override switch allows field technicians to force the load on or off for diagnostic verification.
• 4-inch track mount design ensures seamless integration into standard industrial control cabinets.
• Dual 24Vac/dc coil input offers universal compatibility with modern building automation systems.
• The RIBM24S provides a durable, enclosed solution that replaces the FUN-RIBM2-4S without wiring modifications.

Can the RIBM24S be used with both AC and DC control signals?
Yes, the coil is designed to accept 24V AC or 24V DC, providing flexibility for different HVAC control transformer outputs.

How do I confirm if the override switch is active?
The physical toggle on the device allows you to select 'Hand' for manual override, 'Auto' for system control, or 'Off' for maintenance lockout.

What is the maximum amperage this track mount relay can handle?
The RIBM24S is rated for up to 15 Amps at 120V-277V AC, making it suitable for single-phase motor switching and power distribution.
