AP791

8/12CH Current/Voltage/Thermocouple Fully Isolated Analog Input

Description

AP791 Analog Input Module measures Industrial Voltages, Current and Thermocouples in twelve fully isolated input channels and communicates using the Modbus RTU serial protocol. The AP791 is specially designed for high noise and harsh industrial environments and has an ability to properly eliminate floating noise over input signals and 50Hz/60Hz harmonics
