Industrial Ethernet Digital I/O Control PCBA

The Industrial Ethernet Digital I/O Control PCBA is built for signal acquisition, digital input and output control, and network communication in industrial automation systems. The board features dual RJ45 Ethernet interfaces, multiple field-wiring terminals, a main control MCU, multi-channel signal circuits, and a 24V power input on a single FR-4 PCB. Clearly marked DI and DO channel positions let the board connect with external sensors, switches, actuators, and other industrial devices and exchange control data with the host system through an Ethernet connection. The PCBA provides multiple digital input and output channels set in separate circuit sections. The visible channel markings run from DI1 to DI16 and DO1 to DO16, and COM terminals give common connections for field wiring. Multiple ICs and discrete components sit across the signal channels for input conditioning, isolation, and output driving per the circuit design. This architecture supports PLC expansion, industrial equipme…
