Functional Devices RIBL24B Enclosed Latching Relay 20 Amp SPDT 24VAC/DC

The Functional Devices RIBL24B is an enclosed latching relay designed for low-voltage switching applications in HVAC, building automation, and industrial control systems. This relay features a 20 amp SPDT (Single Pole Double Throw) contact configuration and operates on 24VAC or 24VDC control voltage, making it versatile for various control circuits.

Key Features:

• Latching relay design maintains state without continuous power, reducing energy consumption
• 20 amp resistive switching capacity for controlling motors, heaters, and lighting loads
• Dual voltage operation: 24VAC or 24VDC control input
• SPDT contact configuration provides both normally open and normally closed connections
• Enclosed housing protects relay components from dust and environmental contaminants
• Compact design for easy installation in control panels and junction boxes
• Momentary pulse switching - requires only brief signal to change states

The RIBL24B's latching mechanism makes it ideal for applications requiring bistable operation, such as motorized damper control, pump sequencing, and remote switching where maintaining relay position during power interruptions is critical. The enclosed design ensures reliable operation in commercial and light industrial environments.
