The AMG1051H ultra-thin circuit power supply isolation temperature transmitter digitally linearises the signals of the field thermocouple (TC) or resistance temperature detector (RTD), converting them to isolated outputs of 4-20mA current corresponding to the sensors' temperatures. Isolators have the functions to send out alert messages when the sensors sense a disconnection, and the RC input has an auto cold junction compensation function. It is also able to configure parameters such as scale and index number for the transmitter using professional software.

Note: 1. The output precision of "%" is equivalent to the range of the set, take larger value of range deviation and absolute deviation in the application.

2. The output precision does not include cold end compensating deviation whileTC inputting.

Installation:

The AMG1000 series isolator uses DIN35mm rail mounting.  

Steps for installation:

1)      Mount the metallic portions below the instrument onto the track.

2)      Push the upper metallic portion below the instrument onto the track.
