DK5081 is the remote MODBUS RTU data acquisition module linear signal input measurement, one way DA control function. It can be used as the 8 way analog data remote data acquisition. This product has three terminal isolation function. It is convenient for seamless connection with all kinds of configuration software, touch screen and all kinds of DCS systems. Measurement input 16 bit AD resolution, DA output 12 bit resolution. It can be used as an attachment for PLC measurement.
Product features
Using the latest international electronic technology, the digital intelligent data acquisition and transmission module with high-speed signal processor and microprocessor as the core.
That is to say, one of the 8 choices can be sent and output to the remote, and the other can be selected as a communication remote given DA through parameter setting.
The circuit design uses three terminal isolation of input, power and output.
input
It can measure DC voltage signal in 8 0-5V range.
Or DC voltage signal in 8 0-10V range;
Or DC current signal in the 8 way 0-20mA range.
communication
Equipped with photoelectric isolation RS-485 communication interface, using ModBus RTU communication protocol.
