The Emerson KJ4006X1-BT1 Redundant AO 8-Channel Terminal Block is a specialized high-reliability output terminal block designed for the Emerson DeltaV™ distributed control system (DCS). This terminal block is engineered to support redundant analog output (AO) configurations, providing 8 isolated analog output channels with built-in support for dual-redundant wiring to ensure fault tolerance and system availability in mission-critical operations.

The KJ4006X1-BT1 is ideal for use in safety and control systems that demand maximum uptime and resilience. It enables robust field device connectivity while maintaining signal integrity through industrial-grade isolation and wiring integrity. Designed for DIN rail mounting and compact panel integration, it reduces cabinet space requirements without compromising performance.

Typical deployments include energy production, refining, petrochemicals, life sciences, and other heavy-process environments where equipment reliability and safety are paramount.

FAQ

1. What does “redundant” mean in the context of this terminal block?

   Redundancy means the terminal block can connect two separate analog output cards to a single channel, ensuring one takes over if the other fails.

2. Can this block be used with standard (non-redundant) AO cards?

   No, it is specifically designed for use with DeltaV redundant analog output cards only.

3. Is the signal automatically switched in the event of failure?

   Yes, the DeltaV system handles automatic failover between redundant outputs.

4. What kind of signals does this block support?

   It supports standard 4–20 mA analog output signals per channel.

5. Does it support HART communication?

   The terminal block itself is passive; HART support depends on the paired I/O card.

6. How many wires can I connect per terminal point?

   Each point supports single or dual wires, typically AWG 16–24.

7. Is the terminal block hot-swappable?

   Yes, when used with proper system procedures and the system is in a safe state.

8. Can I use this terminal block outdoors?

   It must be housed inside an IP-rated enclosure to be used outdoors or in harsh environments.

9. What tools are required for installation?

   Basic screwdriver for DIN rail mounting and terminal tightening is sufficient.

10. Can I reuse this block during system upgrades or retrofits?

    Yes, as long as the block is undamaged and compatible with the new system components.
