Overview of Emerson KJ4001X1-CA1 I/O Terminal Block
The Emerson KJ4001X1-CA1 is a specialized I/O terminal block designed to facilitate safe, reliable
signal and power connectivity between field devices and industrial automation systems—specifically
tailored for hazardous environments and critical industrial applications like oil and gas, chemical
processing, and power generation. As a key component of Emerson’s DeltaV™ automation
ecosystem (including the Electronic Marshalling Digital Automation System and CHARM I/O
Subsystem), it ensures secure signal transmission while adhering to strict global safety and
environmental standards, making it suitable for use in potentially explosive atmospheres.
At its core, the terminal block delivers flexible power handling with an input power rating of 250 VAC
or 60 VDC at 1 A per channel, accommodating diverse field device power requirements without
compromising stability. Its environmental resilience is engineered to withstand harsh industrial
conditions: it operates across a wide ambient temperature range of -40 °C to +70 °C, resists 10 g
shock (11 ms half-sine wave), and tolerates vibration (1 mm peak-to-peak at 2–13.2 Hz; 0.7 g at 13.2–
150 Hz). Additionally, it complies with ISA-S71.04 –1985 Class G3 for airborne contaminants and
supports 5–95% non-condensing humidity, ensuring durability in dusty, moist, or chemically exposed
settings.
Safety is a foundational feature, validated by multiple global hazardous location certifications. It holds
ATEX certification (II 3G Ex ec IIC Gc, FM18ATEX0076U), IECEx certification (IECEx FMG 18.0030U), and
FM approvals covering Class I, Division 2 (Groups A,B) and Class I, Zone 2 (AEx/Ex ec IIC T4) hazardous
locations—along with region-specific FM certifications (FM18US0277U, FM19CA0005U,
FM21UKEX0199U) and an LR approval (LR 108860) for broader industry compliance. To maintain
safety during handling, the terminal block cannot be removed or inserted while system power is
energized, and installation/operation must follow guidelines in document 12P2046 ("DeltaV™
Electronic Marshalling Digital Automation System (CHARM I/O Subsystem) Zone 2 Installation
Instructions") and the "DeltaV™ S-Series and CHARMs Hardware Installation" manual.
From a maintenance perspective, the KJ4001X1-CA1 is designed for minimal upkeep: it contains no
user-serviceable parts (disassembly is prohibited) and requires no calibration, reducing operational
downtime and simplifying lifecycle management. Practical identification features include a product
label with serial number, manufacturing location, and date—critical for tracking, warranty validation,
and regulatory compliance.
Overall, the Emerson KJ4001X1-CA1 I/O Terminal Block combines versatile power handling, robust
environmental durability, and rigorous safety compliance, making it a trusted interface component for
industrial automation systems operating in demanding, hazardous, or mission-critical environments.
