Bracket controller is an embedded microcomputer with the software and hardware systems required for a computer system that can autonomously store and run programs. It is able to accept keystroke manipulations, display hint information, collect sensor data, control solenoid valve ports, and perform automatic control and monitoring functions, communicating with other bracket controllers on the desktop and computers with the main control. The parameters required for the electrohydraulic control system can be entered using the keys to achieve online - setting and changing parameters; You can also download the new application online to the controller to implement an online program update. The technical indicators are as follows: Explosion protection type: Mine nature protection level: IP68 Environmental temperature: from -20°C to 60°C Working voltage: DC12V Working current: 200 mA (static) Sensor input: 6 ways Emergency stop buttons, locks: one by one Number of units: 1 unit/unit
