Working Principle:
The VE4003S2B3 analog input card receives 4-20 mA current signals from 4-wire field transmitters through its input channels. The 4-wire configuration allows separate power supply and signal return paths, which is essential for devices that require independent power sources. The internal signal conditioning circuitry processes the current signals, converting them to digital values through high-precision analog-to-digital converters. The digitized measurements are transmitted to the DeltaV controller via the backplane bus. The HART communication circuitry simultaneously extracts digital HART signals superimposed on the analog current, enabling remote device configuration and diagnostics. The card continuously monitors each channel for fault conditions including open circuits, short circuits, and out-of-range signals, providing immediate visual and system-level alerts.
