General Information

Core Description

Engineered for reliable process control loop execution, the KJ3002X1-BB1 (part numbers 12P0683X092 and VE3006) is an Emerson DeltaV™ M-series traditional analog output card delivering 8 dedicated channels of 4-20mA signal transmission. This module slides into standard M-series carriers and connects to field actuators via terminal blocks. For modernization and hardware legacy retention projects, it interfaces seamlessly with the Aparian DV Scanner via an external LocalBus extension system, enabling an Allen-Bradley ControlLogix or CompactLogix processor to capture and read back active channel feedback without replacing functional field-level field infrastructure.

Specific Application

• Traditional Loop Actuation Control: Driving field-level proportional control valves, positioners, dampers, and speed regulators via standard non-HART 4-20mA instrumentation loops.
• Logix Migration and Shadow Systems: Interfacing legacy M-series hardware layouts into modern Rockwell Automation EtherNet/IP trees using a dual-port unmanaged or DLR network scanner configuration.

Ordering Information

System Compatibility

• System Compatibility: The KJ3002X1-BB1 connects to the DeltaV™ M-series LocalBus carrier assembly. For legacy setups, it interfaces directly with native Emerson controllers. For cross-platform Allen-Bradley Logix migration, it is fully supported by the Aparian DV Scanner (A-DVS) via a Right Carrier Extender (KJ4001X1-NA1) using a DB44 male D-shell connection. When mapped to Logix via Studio 5000 EDS Add-On-Profiles (AOP) and standard UDT-mapped Add-On-Instructions (AOI), it consumes a fraction of the scanner’s maximum limits (which accommodates up to 32 card slots and 8 Class 1 CIP connections).
• Direct Application Alternate: KJ3221X1-BA1 (DeltaV™ M-series 8-Channel 4-20mA HART, Series 2 Analog Output Card).
• Key Differences from Alternate (KJ3002X1-BB1 vs. KJ3221X1-BA1):
• HART Communication Support: The KJ3002X1-BB1 is a traditional analog module that manages pure, unmodulated 4-20mA continuous current outputs. It cannot pass or translate digital field diagnostics. In contrast, the newer KJ3221X1-BA1 is an advanced Series 2 module with built-in HART modems on every channel, allowing plant personnel to overlay smart digital field instrumentation data onto the analog signal.
• System Upgrades & Architecture: While both cards provide an identical 8-channel footprint and draw standard LocalBus power, the Series 2 KJ3221X1-BA1 utilizes modified backplane registers optimized for deeper diagnostic structures. The traditional KJ3002X1-BB1 remains highly reliable and cost-effective for baseline variable control loops that do not require digital smart positioner calibration tracking.

Installation & Troubleshooting FAQ

Q1: How do I configure and scale the channels of a KJ3002X1-BB1 card within a Rockwell Automation Logix tree?

A: Hardware scaling and card parameters are not set inside Studio 5000 controller tags. Instead, you must open the free Aparian Slate configuration software environment. Inside Slate, navigate to the IO Bus properties under your active DV Scanner node, select the target slot, and register the card type as KJ3002X1-BB1. Here, you can configure individual channel bounds to match your field actuators before exporting the project data to land on the Logix controller tree.

Q2: I am installing a new KJ3002X1-BB1 card into an active migration bank, but the DV Scanner will not read it. What is wrong?

A: This usually points to a physical bus continuity fault or a slot assignment issue. The DV Scanner relies on a strict hardware sequence over the DB44 connection. First, verify that the KJ4001X1-NA1 Right Carrier Extender is properly locked onto the M-series carrier. Second, check that your D-shell extender cable (such as a 1.2m KJ4002X1-BF2) is securely screwed down into the scanner's male DB44 port. Finally, verify inside Slate that the card's physical slot position exactly matches your software I/O register tree.

Q3: What is the purpose of "Shadow Mode" when operating a KJ3002X1-BB1 card during a plant turnaround?

A: Shadow Mode is a non-disruptive migration architecture. In this mode, your existing legacy DeltaV™ processor maintains active physical control and safety logic over the KJ3002X1-BB1 analog output card. The Aparian DV Scanner acts strictly as a passive listener on the M-series LocalBus, capturing real-time input status and output readback data. This allows engineers to fully test and validate new ControlLogix or CompactLogix program code against live field actions without risking accidental process shutdowns or physical loop interruptions.

Q4: How does the network handle data routing to the KJ3002X1-BB1 card if the main EtherNet/IP cable fails?

A: Network recovery depends on your architecture layout. The companion DV Scanner houses two integrated Ethernet ports. If your system is wired in a standard linear topology, a cable break will sever communications and drop the output card to its unconfigured fail-safe state (0 mA output). To prevent this, configure the system in a Device Level Ring (DLR) topology. In a DLR loop, the internal hardware switch detects a media break and immediately reroutes data packets through the backup port within milliseconds, keeping your 4-20mA loops completely operational.

Q5: Can I hot-swap a KJ3002X1-BB1 analog output card while the LocalBus carrier is powered up?

A: While M-series hardware handles card insertion under power, you must exercise extreme caution. The KJ3002X1-BB1 carries an IP20 NEMA/UL Open Type rating and is designed strictly for a non-corrosive air environment spanning -20 to 70 °C. If your carrier is positioned in a classified explosive area, pulling or seating a card while the bus is live risks triggering an electrical spark transient across the backplane terminals. Always verify the local atmosphere is nonhazardous or isolate the 10-32V DC terminal input power before swapping hardware modules.
