EMERSON KJ2201X1-HA

1. Overview

The EMerson/DeltaV KJ2201X1‑HA1 is a safety‑rated terminal block specifically designed for hazardous areas. It enables reliable signal connection in flammable and explosive environments. This product complies with international explosion‑proof directives such as ATEX and is suitable for field wiring needs in the Emerson DeltaV Distributed Control System (DCS).

2. Specifications

• Explosion Protection Rating: ATEX compliant, with a built‑in Intrinsically Safe design.
• Current Rating:Wiring Method: Screw compression type, supporting quick assembly and disassembly.
  • Between Terminals A‑B: 30 mA (for low‑power signal circuits)
  • Between Terminals A‑C: 1 A (for general power supply or control circuits)
• Operating Temperature Range: ‑25 °C ~ +85 °C (specifically dependent on the installation environment).
• Material: Flame‑retardant plastic housing, with high‑conductivity copper alloy contacts inside.

3. Product Features

• Intrinsic Safety: Minimizes energy output to prevent ignition of surrounding flammable gases.
• Seamless Compatibility with DeltaV: Plug‑and‑play functionality simplifies system integration and on‑site commissioning.
• High Reliability: Features vibration‑resistant and shock‑resistant design, suitable for harsh industrial sites.
• Modular Structure: Allows flexible combination of terminals with different current specifications based on on‑site requirements.
• Easy Maintenance: Screw‑type wiring facilitates quick inspection and replacement.

4. Structure and Composition

• Housing: Made of flame‑retardant plastic, providing protection and meeting explosion‑proof requirements.
• Terminal Block: Divided into three groups (A, B, C), each corresponding to different current ratings.
• Wiring Screws: Equipped with anti‑loosening design to ensure long‑term reliable contact.
• Identification Labels: Clearly mark terminal functions and current specifications for easy on‑site identification.

5. Application Fields

• Petrochemical Industry: Used for process control signal transmission in hazardous areas.
• Natural Gas and Oil Refining: Ensures safe wiring between explosion‑proof instrument panels and on‑site instruments.
• Pharmaceutical and Food Industry: Suitable for production lines that meet both hygiene and explosion‑proof requirements.
• Power and Energy Industry: Used for signal wiring in high‑risk environments such as substations and power distribution cabinets.

6. Installation and Maintenance

Installation

1. Select an installation location that meets explosion‑proof requirements, and ensure the terminal block is away from interference sources such as high temperatures and strong magnetic fields.
2. According to the wiring diagram in the product manual, crimp the corresponding cables to Terminals A, B, and C, and secure them with screws.
3. Check the tightness of the wiring to ensure there is no looseness or incorrect connection.

Maintenance

1. Regularly (recommended every 6 ~ 12 months) check the tightness of the screws and re‑tighten them if necessary.
2. Clean the surface of the terminals to prevent dust and oil from affecting electrical conductivity.
3. If terminal corrosion or damage is found, replace the corresponding module in a timely manner to avoid impacting system safety.
4. Maintenance records should include inspection date, inspector, identified issues, and handling measures to meet safety audit requirements.
