DK2100 series

  • DK21DN guide rail type 8 channel universal input inspection controller data acquisition device

DK21DN guide rail type 8 channel universal input inspection controller data acquisition device

  • Dk21DN 8 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.
