Working Principle:
The VE4002S1T2B6 discrete output card receives digital control commands from the DeltaV controller through the backplane communication bus. The internal logic circuitry processes these commands and activates the corresponding output channels through high-side switching transistors. Each output channel provides a 24 VDC switching signal to control connected field devices. The card incorporates comprehensive diagnostic circuits that continuously monitor output status, detecting conditions such as open circuits, short circuits, and overcurrent situations. The high-side switching topology ensures that the load is connected between the output terminal and ground, providing enhanced safety and simplified wiring for field devices.
