DK2100 series

DK2108 Four channel voltage, current, resistance, temperature signal input program controller

Dk2108 four channel universal signal input type. 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 signal 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.
