Isolated PT100 to Current Voltage Signal Converter

Model: BRT PT100AM

BRT PT100AM PT100 to current voltage signal converter accepts 2-wire or 3-wire PT100 sensor signal input and outputs standard 0-20mA, 4-20mA, 0-5V, 0-10V signal in linear to input temperature range. Its input, output and operating power supply are isolated. Operating power supply is 24VDC.

Main Features:
● 0.2% F.S. accuracy, high linearity, low error.
● 2-wire PT100, 3-wire PT100 signal input.
● 24VDC operating power supply.
● 1.5KV isolation among input, output, power.
● DIN rail-mounting, flame-retardant shell.

BRT PT100AM RTD PT100 to current voltage signal converter is an isolated pt100 to 4-20mA, 0-20mA, 0-5V, 0-10V signal conditioning module. It is widely used in 3-wire PT100 sensor or 2-wire PT100 sensor signal conversion and amplification. Its isolation voltage among input, output, operating power supply is 1.5KV.  Slim shell with heat-sink barrier, anti-surge and anti-interference circuits used ensure its stability and performance. It has input wire-break alarm function, user can set breaking alarm point from 0-22mA. That PT100 to dc converter is an ideal low cost high efficiency RTD PT100 signal conditioning module.
