Overview of Emerson KJ3244X1-BA1 Series 2 DeviceNet Card
The Emerson KJ3244X1-BA1 is a specialized Series 2 DeviceNet Card designed for reliable
communication and integration in industrial and hazardous environments, serving as a critical
interface for connecting field devices to Emerson’s automation systems (such as DeltaV™ Scalable
Process System). Engineered to meet strict safety and environmental standards, it balances robust
performance with compliance for potentially explosive areas, making it suitable for sectors like oil and
gas, chemical processing, and power generation.
At its core, the card enables seamless DeviceNet communication while operating within defined
power parameters: it draws 12 VDC at 600 mA from the LocalBus and 24 VDC at 40 mA from the
DeviceNet network, ensuring efficient power usage without compromising signal integrity. Its
environmental resilience is a key strength—withstanding temperatures from -40 to 70 °C, 10g shock
(11 msec ½ sinewave), and vibration (1mm peak-to-peak at 5–16 Hz; 0.5g at 16–150 Hz)—along with
resistance to airborne contaminants (ISA-S71.04 Class G3) and 5–95% non-condensing humidity, all
rated to IP20 protection for dust ingress.
Safety is prioritized through global hazardous location certifications: ATEX approval (II 3 G, EEx nA IIC
T4, Nemko No. 02ATEX431U) and FM approval (Class I, Division 2, Groups A–D, T4 temperature rating)
confirm its suitability for explosive atmospheres. However, it requires adherence to specific
installation guidelines—including reference to documents 12P2046 and Installing Your DeltaV
Automation System—and cannot be hot-swapped (removal/insertion is prohibited with system power
energized) to mitigate safety risks.
From a maintenance perspective, the card is designed for minimal upkeep: it has no user-serviceable
parts (disassembly is forbidden) and requires no calibration, reducing operational downtime.
Additional practical details—such as a wiring diagram on the card’s left side, terminal block key
position D5, and manufacturing/serial number information on the product label—simplify installation,
identification, and compliance tracking.
Overall, the KJ3244X1-BA1 delivers a combination of communication functionality, environmental
durability, and safety compliance, making it a trusted component for industrial automation systems
operating in demanding and hazardous conditions.
