Functional Devices RIBL4C Enclosed Relay 10 Amp 3 SPST-NO + 1 SPDT 10-30VAC

The Functional Devices RIBL4C is an enclosed relay interface module designed for HVAC and building automation control applications. This versatile relay provides four independently controlled relay outputs in a compact, DIN rail mountable enclosure.

Key Features:

• Three SPST-NO (Single Pole Single Throw - Normally Open) relay outputs
• One SPDT (Single Pole Double Throw) relay output for additional switching flexibility
• 10 Amp resistive load rating per relay contact
• 10-30VAC control voltage range for compatibility with common HVAC control systems
• Enclosed design protects relay contacts and wiring connections
• DIN rail mounting for easy installation in control panels
• LED indicators for visual status monitoring of relay activation
• UL listed for safety and reliability

The RIBL4C is ideal for controlling fans, dampers, solenoids, and other electrical loads in building automation systems. The combination of normally open and SPDT contacts provides maximum flexibility for various control sequences and interlocking applications.
