Emerson KJ4001X1-CA1 I/O Terminal Block Power Interface Module 2 24vdc
KJ4001X1-CA1 Description
The KJ4001X1-CA1 is a fused, field-wired I/O terminal block designed exclusively for Emerson’s DeltaV™ Distributed Control System (DCS) electronic marshalling (CHARMS I/O) architecture. It serves as a critical interface between DeltaV I/O modules and field sensors/actuators, providing integrated overcurrent protection, secure signal termination, and hazardous-area compatibility for digital and discrete I/O circuits. Built for industrial process control environments, it supports Zone 2 / Div. 2 hazardous locations, enables direct field wiring, and ensures reliable signal integrity while protecting system and field devices from short-circuit and overload damage. It is non-hot-swappable and requires power-down for installation/removal, with no user-serviceable internal components.
KJ4001X1-CA1 Key Features
- Integrated Fused Protection: Built-in per-channel fuses for overcurrent/short-circuit protection, eliminating external fuse panels and simplifying wiring.
- Hazardous Area Certified: ATEX / IECEx / FM approved for Zone 2, Div. 2 (II 3G Ex ec IIC Gc, T4), suitable for oil, gas, chemical, and refining installations.
- DeltaV CHARMS Compatibility: Seamlessly mates with DeltaV CHARM I/O modules, supporting discrete digital I/O (DI/DO) field signal termination.
- Robust Industrial Design: IP20 protection, vibration/shock resistant, rated for ISA-S71.04 Class G3 harsh industrial environments (high dust, corrosive gases).
- Secure Field Wiring: Screw-terminal connections for reliable field wiring, supporting 24 VDC field circuits up to 250 VAC / 60 VDC per channel.
- Compact DIN-Rail Mount: Standard 35 mm DIN-rail mounting for easy installation in control cabinets, space-efficient design.
- No Calibration Required: Maintenance-free operation, no internal adjustments or calibration needed for reliable long-term performance.
- Global Safety Approvals: CE, ATEX, IECEx, FM, CSA certified for worldwide industrial deploymentEmerson.
