Product Description

Product overview

It can convert the 4-channel RTD/TC/Resistor/mV signals from the industrial field to the digital signals, and according to the MODBUS protocol, through the RS 485 communication provide digital signals to PHM-7100, PLC or host computor controllers or data acquisition systems. Compare to the traditional PLC+ signal isolator output mode, it has reduced the errors through two conversions, it can significantly increase the conversion accuracy at the same time increase the stability and anti-interference ability.
