FAQ

Q: What is Sequence of Events (SOE) used for?
A: SOE cards timestamp discrete state changes (e.g., relay trips, limit switches) to reconstruct the exact order of events during a process upset or safety trip.

Q: Can this card be hot-swapped?
A: Yes, under specified safe power conditions when installed in a supported redundant or non-critical slot configuration.

Q: What terminal block do I need?
A: Use a rotary-keyed terminal block set to position C5 for proper compatibility.

Installation Guidelines

1. Set the terminal block key to C5.
2. Install the card into an available DeltaV carrier slot.
3. Connect dry-contact field wiring to the terminal block per channel.
4. Verify timestamp synchronization with the DeltaV controller clock.

Selection Tips

• Choose KJ3008X1-BA1 when you need millisecond-level event logging for safety or process diagnostics.
• Confirm your DeltaV controller supports SOE timestamp synchronization.
• Ensure field devices provide dry-contact closures compatible with 24 VDC sensing.
