  • Page 3: Application

    User Manual 1. APPLICATION S4AI module is designed to measure the standard signal (voltage, current, temperature, resistance, etc.) and to provide the measured values in a digital form via the MODBUS protocol. Input signals are divided into two groups of two inputs which are insulated with each other. RS485 interface and USB are isolated from the input, output signals and from the power supply.
