Description
The Honeywell 51308448-526 Auxiliary Output Card is an electronic interface module designed to expand control capabilities in HVAC systems. It is mounted in the control panel of the system, and receives signals from the main control board, and provides more output channels to control the auxiliary components like dampers, fans or pumps. The card is used in commercial and residential air handlers, furnaces, and packaged units and provides coordinated control of secondary components that assist in temperature regulation, ventilation, or secure operations.
