Overview

The PHR-4000 series is a signal input and output module based on the RS-485 industrial bus, using the Modbus RTU communication protocol. They provide functions such as analog input/output, digital input/output, and temperature input.
PHR-4017I has 8 independent differential current input channels, and each channel signal type can be set independently. It has the characteristics of high accuracy, strong isolation and voltage resistance, and high EMC level.
