GENERAL DESCRIPTION

TRxxxPW series thermal resistance isolator which are

mainly applied in industrial automation systems can isolated

convert thermal resistance input signal of the industrial field

instruments to the matched analog output signal for the

DCS/PLC, realizing the acquisition and transmission of field

signal.

An independent power supply is needed for

the

product

and the port of power supply, input and output are isolated from

each other. This series of products contain combinations of 1

input 1 output , 1 input 2 output, 2 input 2 output and so on.

The thickness of 12.5mm meet the need for high density field

installation.

Connection of field devices and the regions:

2-wire, 3-wire thermal resistance
