DK2104 independent eight way inspection control instrument DK2100 series multi-channel instruments, including Dk2104 eight-way universal ** input type, DK2108 four-way universal ** input type, DK21H8 four-way universal ** input type, DK21DN eight-way universal input guide installation version. It can be used in conjunction with various sensors and transmitters. It can detect, alarm and control industrial process parameters such as multi-channel temperature, pressure, liquid level, flow rate, weight, current and voltage, and transmit output, data acquisition and communication. With the latest international electronic technology, high-speed ** processor and microprocessor as the core, digital is more intelligent. Equipped with photoelectric isolation RS-485 communication interface, using ModBus RTU communication protocol. The circuit design uses three terminal isolation of input, power and output.
