Analogue input module

February 2025 Fieldbus & Industrial Networking

The D6400 analogue input module from Vepac contains seven differential inputs for measuring DC voltages, current signals such as 4-20 mA and thermocouple temperature sensors. Each input channel can be configured to measure one of six voltage ranges, eight thermocouple types or a current input such as 4-20 mA.

The D6400 performs all signal conditioning, cold junction compensation for thermocouples,16-bit analogue to digital conversion and linearisation, and stores the result in a 16-bit unsigned integer format. The unsigned integer data values represent a percentage of the temperature input full scale range. The data values are transmitted to any supervisory host computer that supports the Modbus RTU serial protocol.
