Process Control and Signal Isolation Features
The module delivers 16-bit resolution across 16 channels, enabling continuous acquisition of 4-20 mA HART loop protocol signals from field transmitters. Integrated channel-to-channel isolation prevents differential ground loops from corrupting measurement values or propagating transient voltage noise to the LocalBus logic carrier. Internal cold junction compensation (CJC) routing on adjacent baseplates supports stable temperature conversions, maintaining loop calibration integrity across high-density industrial control cabinets.
Frequently Asked Questions
Q: What are the primary backplane current draws for the VE4035S2B1 module?
A: The module draws 12 VDC at 150 mA from the internal LocalBus rail and 12 VDC at 300 mA from the bussed field power connection, delivering up to 24 VDC at 32 mA per field circuit.
Q: Does the VE4035S2B1 support hot-swappable replacement on active DeltaV baseplates?
A: Engineers can perform hot-swappable installation and removal of the module on energized DeltaV I/O baseplates without disrupting adjacent I/O slots or interrupting backplane communication.
Field Installation Guidelines
- Seat the module firmly onto the designated DeltaV carrier slot until the top and bottom mechanical latches click into place.
- Route all 4-20 mA field transmitter wiring through shielded twisted-pair cables to preserve 16-bit analog-to-digital conversion accuracy.
- Terminate signal cable shields at a single point on the cabinet instrument ground bar to prevent circulating ground currents.
- Maintain physical separation between 24 VDC analog input field wiring and high-voltage AC power cables in cabinet wireways.
