Description: This PCB assembly is designed for industrial automation and equipment control systems. It integrates a low-power MCU, multi-channel optocoupler isolation circuits, and digital I/O interfaces to provide reliable signal acquisition, electrical isolation, and control functions.The board is used for monitoring and controlling industrial field signals, including switch inputs, sensor status signals, and external control outputs. The optically isolated design improves system reliability by protecting the main controller from electrical interference and voltage fluctuations in industrial environments. LJPCB provides one-stop PCBA manufacturing services, including PCB fabrication, component sourcing, SMT assembly, functional testing, and turnkey electronics manufacturing solutions.
