Product Overview

The TURCK MK33-LI-EX0 is a rugged, explosion-proof industrial interface module engineered to enable safe and reliable signal conversion and transmission in hazardous environments—critical for industries such as oil and gas, chemical processing, and pharmaceutical manufacturing. As a core component of TURCK’s hazardous-area product lineup, the TURCK MK33-LI-EX0 excels at isolating and conditioning analog signals (e.g., from pressure, temperature, or flow sensors) to ensure compatibility with upper-level control systems (PLCs/DCSs), while meeting strict explosion-protection standards. Key features include intrinsic safety (Ex i) certification, wide temperature tolerance, and robust chemical resistance—enabling the TURCK MK33-LI-EX0 to operate seamlessly in Zone 0/1 (gas) and Zone 20/21 (dust) hazardous areas. By bridging sensor data and control systems in high-risk environments, the TURCK MK33-LI-EX0 enhances operational safety, reduces downtime, and ensures compliance with global hazardous-area regulations. Hainan Jinlin Mechanical & Electrical is a distributor of industrial control products, specializing in a wide range of brands. We possess extensive industry knowledge and market insights. Adhering to the “Customer First, Forge Ahead” business philosophy, we provide high-quality customer service. We’re here for you, dedicated to meeting your needs!

Key Features and Benefits

Explosion-Proof Safety Compliance

The TURCK MK33-LI-EX0 is certified for intrinsic safety (Ex ia IIC T4 Ga) and dust ignition protection (Ex ta IIIC T135°C Da), making it suitable for the most demanding hazardous areas—including oil refinery process vessels, chemical storage tanks, and pharmaceutical powder-handling systems. Its design prevents electrical sparks or excessive heat from igniting flammable gases, vapors, or dust, eliminating the risk of explosions. This certification ensures compliance with global standards (e.g., ATEX, IECEx, UL 913), reducing regulatory compliance burdens for end-users.

Signal Isolation and Conditioning

Equipped with 500 V AC galvanic isolation between input, output, and ground, the TURCK MK33-LI-EX0 protects sensitive control systems from electrical noise, ground loops, and voltage surges common in industrial environments. It also conditions analog signals (4-20 mA DC) to maintain signal integrity over long cable runs (up to 100 meters), ensuring accurate data transmission from field sensors to PLCs/DCSs. This is critical for applications like pressure monitoring in oil pipelines, where signal distortion could lead to incorrect process control or safety hazards.

Durability and Environmental Resistance

Constructed with glass-fiber reinforced polyamide (PA), the TURCK MK33-LI-EX0 withstands chemical exposure (e.g., oils, solvents, corrosive gases), mechanical impact, and extreme temperatures (-40°C to +60°C). Its IP67 ingress protection rating prevents dust and water ingress, ensuring reliable operation in harsh outdoor or wet indoor environments (e.g., offshore oil platforms). Hainan Jinlin reinforces this durability with a one-year warranty for the TURCK MK33-LI-EX0, paired with specialized pre-sales support (e.g., hazardous-area application consulting) and post-sales services (e.g., technical troubleshooting for Ex-certified setups).
