Solemn commitment: the company sold all the new instruments are genuine, products enjoy the factory direct warranty, free from your worries. A large number of cash stock, need to be customized by the factory shipped directly to your place, without any link in the middle, with fast aging to your hands. Let you worry free shopping!! Because the meter function is more, we can not list one by one, so before the shooting, please confirm the function and price with the customer service. The instrument only shows the function of the default, if you need to alarm, please add alarm function. Other functions in turn are analogous. Please contact our online customer service in time, we will solve the problem for you!!

NHR-7400/7400R Series LCD four way artificial intelligence regulator / regulator recorder

1415954936304105.gifSummary

NHR-7400/7400R series four - way LCD artificial intelligence regulator / recorder uses artificial intelligence formula, instrument start self tuning function, according to the characteristics of the controlled object, automatically find the optimal parameters to achieve good control effect, without manual tuning parameters. The accuracy of temperature control is up to + 0.1, without overshoot or undershoot, reaching advanced level. Four way independent PID regulation, according to the production control requirements switch selection, single point control and program segment control two ways. It is suitable for the control system which needs high precision measurement. It can control the temperature, pressure, flow, liquid level, speed and other measurement signals.
* 4 full signal input, input DC current, DC voltage, MV, thermal resistance and thermocouple signal; 0.2 level measuring accuracy.
You can choose the control point control or multi curve.
It has voltage and current, SSR drive, single / three-phase thyristor zero trigger, relay contacts control output options.
The self-tuning function of PID parameters. The control output, manual / automatic switch without disturbance function, control accuracy and no overshoot.
It supports RS485, RS232 serial interface, using standard MODBUSRTU communication protocol.
It supports RS232C print function, print function, print with manual timing.
* DC24V feed output, as the transmitter site distribution.
People with USB data transfer function and SD card expansion function.
Can input and output, power supply, communication between each other by photoelectric isolation technology.

According to the control mode can be divided into the following categories:

NHR-7410/7410R
Four way PID regulator / recorder
It can input four channel measuring signal, which is compared with the set control target value, and outputs four independent control signals according to the PID operation result. The voltage, current, SSR drive, single / three-phase thyristor zero trigger and other control output modes can be selected.
NHR-7440/7440R
Four way program regulator / recorder
The four way measuring signal can be input, according to the requirements of the production process, the target curve is set to control, and the operation of the curve control, step, pause, end, wait state can be realized. With the function of power off and self starting, the temperature rise is started from the same value of the upper measuring value and the setting value, and the control is carried out according to the original setting curve.
