Functional Devices RIBU1S Enclosed Pilot Relay 10A SPST-NO with Override

The Functional Devices RIBU1S is an enclosed pilot relay designed for reliable switching control in HVAC, building automation, and industrial control applications. This versatile relay features a single pole, single throw normally open (SPST-NO) contact configuration with a 10-amp resistive rating, making it suitable for controlling motors, fans, pumps, and other electrical loads.

Key Features:

• 10 amp resistive contact rating for dependable load switching
• SPST-NO contact configuration (single pole, single throw, normally open)
• Dual coil voltage options: 10-30 VAC/DC or 120 VAC for flexible installation
• Built-in manual override switch for testing and manual control
• Compact enclosed design protects internal components from dust and debris
• DIN rail or surface mounting options for easy installation
• LED indicator light shows coil energization status
• UL recognized and CSA certified for safety compliance

The manual override feature allows technicians to bypass the coil control for troubleshooting or temporary manual operation. The low-voltage coil option (10-30 VAC/DC) makes this relay ideal for integration with modern control systems, thermostats, and energy management systems, while the 120 VAC option supports traditional control circuits.
