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.

Technical indicators

Product characteristic

1. Low power consumption design, low temperature drift, automatic zero calibration.
2. Totally isolated between four channel input signals/communication/power supply
3. Support hot-plug
4. The MODBUS RTU communication protocol is supported, and the communication rate is as high as 115200bps.
5. Support power supply and communication in two ways: backplane mounting rail and terminal.
6. Combined used with PHM-7100 to support MODBUS TCP/IP, so that to simplify the installation and maintenance, and to improve the data transmission performance.
7. Each input signal can be set through programming: RTD/TC/Resistor/mV signals
