Functional Devices RIBMN24Q4C-PX 4-Stage Relay Module 0-10VDC Control 24VAC/DC

The Functional Devices RIBMN24Q4C-PX is a field-adjustable staging threshold relay module designed for precise control of HVAC equipment and multi-stage systems. This compact relay module accepts a 0-10 VDC control signal and provides four independent SPDT relay outputs that can be configured to stage equipment on or off at user-defined voltage thresholds.

Key Features:

• Four SPDT relay outputs for flexible staging control
• 0-10 VDC control input with field-adjustable thresholds
• 24 VAC/DC power input for universal compatibility
• 2.75-inch track mount design for quick DIN rail installation
• Field-configurable staging points allow customization for specific applications
• Compact enclosure saves panel space in control systems
• Ideal for economizer control, heating/cooling staging, and VAV applications

This relay module is commonly used in building automation systems to convert analog control signals into discrete relay outputs for sequencing compressors, heaters, dampers, and other staged equipment. The adjustable thresholds provide flexibility to match equipment requirements without programming.
