Working Principle:
The VE4003S2B2 analog input card receives 4-20 mA current signals from field transmitters through its 2-wire input channels. The internal signal conditioning circuitry converts the current signals to voltage signals, which are then processed by high-precision analog-to-digital converters. The digitized values are transmitted to the DeltaV controller through the backplane communication bus for process control calculations. Simultaneously, the HART communication circuitry extracts the digital HART signals superimposed on the 4-20 mA analog signal, enabling bidirectional communication with smart field devices. The fused terminal blocks provide overcurrent protection, while the diagnostic circuits continuously monitor channel status for fault conditions such as wire breaks or short circuits.

Installation Requirements:

  • Install in a control cabinet or electrical enclosure
  • Mount on DIN rail securely
  • Ensure proper backplane connection to DeltaV carrier
