Smart Isolator Overview
The on-site DC voltage or current signal is transmitted through isolation and converted into the required signal to 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 the stability and reliability of the system Sex.
With display unit, you can set the parameters of each channel and switch between each channel by touching the keys.
