Data acquisition module

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

DK21DN can be used in conjunction with various sensors and transducers. It can detect, alarm and control industrial process parameters such as temperature, pressure, liquid level, flow rate, weight, current and voltage, 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.
