FAQ

Q: What does the suffix *B indicate on the FCA4 module?
A: The suffix letter denotes the hardware revision level. FCA4*B indicates Revision B. Earlier revisions include FCA4*A. Verify compatibility with your specific CENTUM system version before ordering.

Q: Which DCS platforms are compatible with FCA4*B?
A: The module is designed for Yokogawa CENTUM VP and CENTUM CS 3000 series Distributed Control Systems.

Q: What sensor types can connect to this module?
A: The module accepts inputs from pressure transmitters outputting 4-20 mA, mV signals, or HART-enabled smart transmitters.

Q: Is the module isolated from the field side?
A: Yes. The module provides galvanic isolation between field sensor inputs and the system backplane to protect against ground loops and electrical noise.

Installation Guide

1. De-energize the DCS rack before installing the module
2. Align the FCA4*B module with the card nest guide rails
3. Insert the module firmly until the backplane connectors engage fully
4. Connect 24 V DC power to the rack power distribution
5. Wire pressure transmitter signals to the module input terminals per the wiring diagram
6. Configure the module parameters in the CENTUM VP engineering station
7. Verify LED indicators display normal run status

Selection Tips

• Select FCA4*B for pressure/DP measurement in CENTUM VP/CS 3000 systems
• Verify your DCS software version supports Revision B hardware
• For earlier system versions, confirm compatibility with FCA4*A
• Order compatible pressure transmitters with 4-20 mA or HART output
• Ensure the card nest has available slots for module installation
