Description
The Carrier 48TM504494 I/O Flex Control Board is an electronic module that manages communication and logic sequencing between sensors, relays, and operational components in compatible HVAC equipment. It processes incoming electrical signals from field detectors and distributes command outputs to coordinate equipment response during different operating conditions. Installed within packaged system controls, it acts as the central interface for monitoring inputs and executing control operates that regulates start-up, shutdown, and safety interlocks. The board maintains coordinated interaction between electrical subsystems to support stable and controlled equipment conduct in HVAC systems.
