Refrigeration Equipment Relay Control PCBA

This relay control PCBA is designed for centralized logic control and electrical load switching in refrigeration systems. It features multiple power relays, an STC microcontroller, terminal connections, and control circuits to manage various equipment functions. The board has clearly labeled spots for the refrigeration valve, defrost valve, power switch, transformer connections, and restart functions. These dedicated positions make it easy to connect refrigeration controls and manage external loads. At the core of the relay control PCB, the STC microcontroller handles logic processing for equipment operation, and multiple relays switch connected loads based on control signals. The board also carries a fuse, safety capacitors, plug-in connectors, and several terminal blocks for external device and signal connections. This setup combines signal I/O, logic processing, and relay switching on a single control board. Specific operating voltage, relay ratings, and electrical load parameter…
