Temperature Transfer and Conversion Module
Features
1. Imported core, according to the application of a variety of principles of the chip to choose.
2. Optional output: 4-20mA, RS485, etc.
3. Good long-term stability, excellent anti-interference performance, etc.
4. Obtain ROHS and CE certification.
Application
Intelligent temperature transmission isolation safety gate (thermocouple, thermal resistance input) for thermocouple, thermal resistance or other millivolt signals in dangerous areas of the field.
The input, after isolation, is converted into a standard DC signal output to the safe zone of the control.
System or other instrument. It's an intelligent temperature transfer isolation safety grid, yes.
USB interface, the input thermocouple can be programmed by PC and control software.
Type and range range, and the zero and full degree of the output signal can be checked.
Single channel, one input, one output. The isolation safety fence is self-contained.
The input/output/power channels are isolated from each other by the DC power supply.
