ABB 3BDH000741R1 CTI21-P Ex Explosion-Proof Control Interface Module

Explosion-Proof Rating: Complies with international explosion-proof standards (such as IEC 60079, ATEX, etc.), ensuring safe operation in explosive gas environments (e.g., Zone 1/2 or Zone 21/22).

Protection Structure: Adopts flameproof (Ex d) or increased safety (Ex e) design. The housing features impact resistance, dustproof, and waterproof capabilities to ensure internal circuits are unaffected by external hazardous environments.

I/O Interfaces: Supports transmission and conversion of multiple electrical signals (e.g., analog, digital), enabling connection to sensors, actuators, or control systems.

Communication Protocols: May be compatible with industrial communication protocols such as Modbus, Profibus, EtherNet/IP, etc., to realize data interaction with upper computers or PLCs.

Operating Temperature: Typically supports -20°C to +60°C (subject to the product manual), adapting to harsh industrial environments.

Anti-Interference Capability: Features electromagnetic compatibility (EMC) design to resist electromagnetic interference in industrial fields and ensure stable signal transmission.

Redundancy Design: Key circuits may adopt redundant configurations to reduce the risk of single-point failures.

Self-Diagnosis Function: Built-in fault monitoring mechanism provides real-time feedback on equipment operation status for convenient maintenance and repair.

Oil and Gas: Scenarios with flammable and explosive gases such as drilling platforms, refineries, and natural gas processing stations, used for motor control, valve regulation, or pressure monitoring systems.

Chemical Industry: Chemical raw material production, storage, and transportation links, such as reactor control and pipeline pressure protection.

Coal Mines and Dust Environments: Suitable for electrical equipment control in underground coal mines (dust explosion-proof) or flour/grain processing workshops (dust explosion risk areas).

Offshore Platforms and Ships: Moist, highly corrosive environments with potential explosive gases, such as offshore oil and gas extraction platforms and oil tankers.
