Resideo by Honeywell SDCR Slave Damper Control Relay 4PDT

The Resideo by Honeywell SDCR is a slave damper control relay designed for use in zoned HVAC systems. This 4PDT (4-Pole Double-Throw) relay provides the switching capability needed to control motorized dampers in multi-zone heating and cooling applications.

Key Features:

• 4PDT relay configuration for versatile switching applications
• Designed specifically for slave damper control in zoned HVAC systems
• Compatible with Resideo/Honeywell zone control panels
• Enables coordinated operation of multiple zone dampers
• Reliable switching for 24VAC damper motor circuits

This relay is typically used in conjunction with a master zone control panel to coordinate the opening and closing of dampers based on individual zone calls for heating or cooling. The SDCR provides the additional relay contacts needed when controlling multiple dampers beyond the capacity of the main control board.
