1Overview

The main function of the signal isolator is to isolated transmit the
input DC voltage (current) signal into the standard current or
voltage signal. The product contains two efficient micro power
isolated power supplies that provides an isolated power supply to
the pre-stage primary sensor while powering the internal signal
processing circuitry. The products are widely used in analog
signal isolation conversion of industrial field, such as
communications, power rail, industrial control and other
automation and control fields
Features:
Ø
Fully isolated circuit structure:
Ø
Two signal inputs are isolated from each other; two signal
outputs are isolated from each other; signal input, output and
auxiliary power supply are isolated from each other;
Ø
Using electromagnetic isolation technology, stable and
reliable performance;
Ø
The output port and power port can withstand 2KV surge
impact;
Ø
The accuracy is better than 0.2;
Ø
Provides the isolated 24V distribution power output,
facilitates a sensor power supply;
Ø
Using 18mm thin shell guide rail installation, space
utilization is high;
Ø
Wiring using plug terminals, easy wiring and maintenance.
