Product introduction

The rail-type intelligent isolator transmits the on-site DC voltage or current signal through isolation and converts it into the required signal for other instruments. It can be used in conjunction with the unit combination instrument and DCS, PLC and other systems to give field instrument signal isolation, signal conversion, signal distribution, signal processing, etc., thereby improving the anti-interference ability of the automatic control system in the industrial production process and ensuring system stability and reliability Sex. With display unit, you can set the parameters of each channel and switch between each channel by touching the keys.

Detailed introduction

 

Smart Isolator

Single-channel, dual-channel.
It can measure 16 kinds of DC voltage (millivolt) / current signals. Users can set any input type according to their needs.
Analog, RS485 output.
Input / output / power magnetic isolation.
Transmission accuracy (20 ℃): 0.2% FS ± 1 word.
The response time reaches 50% of the final value in 50ms.
Wide power supply (AC / DC20-260V).
Fully intelligent, digital and programmable.
Plug-in terminals for easy installation and maintenance.
Standard 35mmDIN rail card installation.
Programmable high-definition display unit can realize PV (measured value) and SV (output value) display on the same screen. The display content can be set according to menus and various combinations, which is convenient for on-site debugging, maintenance and troubleshooting of equipment.

Instrument selection

Remarks:

When RS485 communication is selected for output I, there is no output II function.

Model example: NHR-X31-27 / 27-0 / 0-A

, The dual input signal is 4 ~ 20mA, the dual output signal is 4 ~ 20mA, and the power supply DC / AC20 ~ 260V.
