Dual-System Relay Control Board PCBA

The dual-system relay control board PCBA is for equipment that needs centralized control of multiple electrical loads and two separately identified operating sections. The PCB combines multiple power and signal relays, control circuitry, and external connections on a single mainboard. Dedicated board markings for the compressor, motor, power switching, and other connections point to its role in coordinating several equipment functions through one control platform. Multiple relays spread across the board give switching channels for connected loads, and the central control section holds the main controller and supporting signal-processing circuitry. Numerous wire-to-board connectors provide interfaces for external devices and I/O signals, and visible RX, TX, GND, and 12V markings identify an additional signal connection area. Power-related sections sit apart across the PCB with neutral-line and high-voltage warning markings. Exact operating voltage, relay ratings, load capacity, and co…
