IOK-4 is a multi-functional marine I/O control printed circuit board designed for ship automation control systems. It integrates abundant digital input, relay output and signal conversion circuits, equipped with standard D-SUB and multi-terminal connectors for convenient wiring connection with ship monitoring equipment, sensors and actuators. The board is built with industrial-grade relays, anti-interference filter inductors and stable power supply circuits, featuring strong anti-vibration, anti-electromagnetic interference performance to adapt harsh marine engine room environment. It is widely applied in ship valve remote control, alarm monitoring and auxiliary machinery automatic control systems for signal collection and logic output control.
