Functional Devices RIBU2S2 Relay

The Functional Devices RIBU2S2 is a versatile enclosed pilot control relay designed for reliable switching in building automation, HVAC, and industrial control systems. This pre-packaged relay features 2 SPST normally open (N/O) contacts, providing an efficient solution for controlling multiple loads from a single input source. Built with veteran contractors in mind, the RIBU2S2 supports a multi-voltage input range of 10-30 Vac/dc or 120 Vac, making it an ideal choice for dry contact switching and BAS integration. The internal 10 Amp relay is rated for general use and resistive loads, ensuring durability in demanding mechanical room environments. The heavy-duty NEMA 1 housing includes a 1/2" NPT nipple for direct mounting to electrical boxes, simplifying the relay installation process. By utilizing this pre-wired relay module, technicians can reduce wiring errors and labor time, ensuring consistent performance in lighting control and motor interlock applications.

• Dual SPST-NO Contacts: Provides two independent normally open poles for simultaneous control of separate circuits.
• Flexible Input Power: Operates on 10-30V AC/DC or 120V AC, eliminating the need for multiple SKUs on the service truck.
• LED Status Indicator: Features a high-visibility LED to provide immediate relay coil status verification during troubleshooting.
• Rugged Construction: Enclosed in a flame-retardant UL Listed housing suitable for installation in plenum spaces.
• Contractor Friendly: Pre-wired leads and external mounting nipple streamline the control circuit integration.

Can the RIBU2S2 be used to switch inductive loads?
Yes, the RIBU2S2 relay is rated for 1/3 HP at 120 Vac and 1/2 HP at 240 Vac, making it suitable for small motor loads and inductive fans.

What is the maximum current draw of the coil?
The coil current is approximately 33 mA at 30 Vdc and 47 mA at 120 Vac, ensuring compatibility with standard BAS controllers and 24V transformers.

Is this relay suitable for outdoor use?
The RIBU2S2 features a NEMA 1 enclosure intended for indoor use. For outdoor applications, the relay should be housed within an appropriately rated NEMA 3R or NEMA 4 enclosure.
