DK2004C LCD four loop position type process control instrument

DK2000C series is a four-loop position control instrument with high measurement accuracy. It has four-way position control function. It can also choose one-way transmission output or standard MODBUS RTU communication function. OLEDdisplays the full information and alarm function of the four loop on the same screen. Humanized design UI design, customers can more easily use the upper hand operation. The temperature control instrument adopts OLED liquid crystal design, which improves the characteristics of traditional LCD liquid crystal, such as small angle of view, unclear, easy damage of backlight and so on. The four loop can independently set up the positioning control function. The internal 20 bit high precision AD measurement. The system adopts modular design function of independent intellectual property rights. Four loop universal input and different signal input functions.

Product features

With the latest international electronic technology, high-speed signal processor and microprocessor as the core, digital is more intelligent. The measurement accuracy is higher.

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.

The input of 4 independent channels can connect 26 common industrial signals.
