PHM-7240 Four-channel digital input modul
Product overview
It can convert the four channel digital signal in the industrial field respectively isolated into the digital signals, and according to MODBUS protocol provide the digital signals to PHM7100, PLC or host computer controllers or data acquisition systems. The perfect isolation design concept is very suitable for complex working conditions in industrial field, with good stability. Each circuit provides isolated contact detection power supply, which increases the reliability and anti-interference performance.
