Functional Devices RIBRL1S Relay

The Functional Devices RIBRL1S is a specialized DIN rail mount latching relay engineered for reliable control within HVAC and industrial automation systems. Designed for low-voltage signal management, this 10 Amp SPST-NO relay operates efficiently on a 10-30Vdc control voltage, making it ideal for interfacing with dry contact controllers in complex sequences. Unlike standard relays, the RIBRL1S utilizes a latching mechanism that maintains its contact state even during power interruptions, ensuring consistent performance in critical circuit logic. The compact enclosed relay design mounts directly to 35mm DIN rail, optimizing panel space for contractors during field installations. Its single pole single throw configuration provides a robust solution for switching 10A resistive loads or pilot duty air conditioning circuits. By eliminating the need for an external enclosure, this RIB relay streamlines the wiring process for technicians requiring high-precision low voltage latching controls in building management systems (BMS).

• Internal Latching Logic: Maintains state through power cycles, making it suitable for HVAC automation and safety interlocks.
• Compact DIN Rail Design: Standard 35mm mounting reduces installation time and improves control panel organization.
• Flexible DC Input: Wide 10-30Vdc input range ensures compatibility with various DDC controllers and 24Vdc power supplies.
• Heavy Duty Contacts: Rated for 10 Amp resistive and 1/3 HP motor loads, providing versatile switching capabilities.
• Pre-wired Convenience: Simplifies field connections while protecting internal components in a UL listed enclosure.

What is the difference between a pulse to on/off and a latching relay?
The RIBRL1S is a latching relay that toggles its state with each pulse from the 10-30Vdc source. It does not require continuous voltage to hold the contacts closed, reducing energy consumption and heat within the electrical cabinet.

Can this relay be used for lighting control applications?
Yes, given its 10A ballast rating and latching capability, it is frequently used to manage lighting circuits where maintaining the "on" state during a momentary power loss is required.

Does this unit include a manual override switch?
The RIBRL1S is focused on automated latching logic; technicians should verify specific model suffixes if local manual control is required for maintenance bypassing.
