Key Features

• 8-channel redundancy ensures backup for critical analog control loops
• Each channel includes fused protection for enhanced safety
• Rotary keying prevents mismatched I/O card installation
• Hot-swappable under safe wiring conditions (no field power, no I/O card installed)

FAQ

Q: What type of signals does this terminal block support?
A: It is designed for analog output signals, typically 4–20 mA loops driving control valves or VFDs.

Q: Can I replace this block without shutting down the DeltaV system?
A: Yes, but only when no I/O card is installed and no field wiring is connected. Otherwise, de-energize field power first.

Q: What key position is required?
A: Set the terminal block key position according to the specific AO I/O card installed.

Installation Guidelines

1. Remove field power before connecting or disconnecting the terminal block.
2. Set the rotary key to match the AO I/O card.
3. Connect analog output wiring (4–20 mA) to the designated terminals.
4. Verify fuse integrity per channel before energizing field power.

Selection Tips

• Select KJ4006X1-BT1 for redundant analog output termination in S-Series systems.
• Confirm your AO card calls for the BT1 terminal block key position.
• For non-redundant applications, a simplex terminal block may be sufficient.
