Integration with DeltaV Systems
The KJ2201X1-PW1 is designed for seamless integration into DeltaV DCS architecture:
Mounting: Compatible with standard DIN rail (35 mm) for easy installation in control cabinets, aligning with DeltaV I/O rack mounting standards.
Power Distribution: Serves as an interface between system power supplies (e.g., KJ3001X1-BJ1) and downstream components, ensuring regulated power delivery to I/O modules and field devices.
Labeling: Pre-marked terminals for "LINE," "LOAD," and "GROUND" to simplify wiring and reduce installation errors.
Safety Features: Includes built-in barriers to prevent accidental contact with live parts, enhancing operator safety during maintenance.
Safety & Compliance
Certifications: Complies with IEC 60947-7-1 (low-voltage switchgear and controlgear) and UL 1059 (terminal blocks), meeting global safety standards.
Hazardous Area Suitability: Suitable for general industrial environments; for Zone 2/Division 2 applications, consult Emerson’s hazardous-area terminal block variants.
Installation Requirements: Must be installed by qualified personnel following local electrical codes (e.g., NEC, IEC) and DeltaV system wiring guidelines.
Application Scenarios
The KJ2201X1-PW1 is typically used in:
Power distribution for DeltaV I/O racks and field instrument loops.
Connection of 24 VDC power supplies to sensors, actuators, and transducers.
Wiring harnesses in control cabinets where secure, organized power connections are critical.
Retrofit projects to upgrade legacy terminal blocks with modern, reliable alternatives.
Maintenance & Handling
Inspection: Periodic visual inspection recommended to check for loose connections, corrosion, or damage—especially in high-vibration or humid environments.
Replacement: Tools required (screwdriver or torque wrench) to secure terminals; torque to 0.8–1.0 N·m (7–9 lbf·in) for optimal connection.
Lifecycle: Designed for a service life of 10+ years under nominal operating conditions, matching the lifecycle of DeltaV system components.
Safety Warnings
SIS Logic Integrity: Do not modify safety logic without revalidation (ensures compliance with IEC 61511 and avoids unintended safety function failures).
Power Supply Compliance: Use only Emerson-approved redundant 24 VDC power supplies (prevents overvoltage/overcurrent hazards in hazardous areas).
Communication Network Safety: The DeltaV SIS communication network (e.g., Ethernet/RS485) must not connect to sources exceeding 60 VAC or 75 VDC (avoids electrical shock and arc risks).
