Turck BL67-2AI-I Analog Input Electronic Module

Description:

The TURCK BL67-2AI-I analog input electronic module is used in BL67 distributed I/O systems for acquiring and transmitting analog current signals from field instrumentation to PLC and control systems. Commonly installed in process skids, water treatment facilities, chemical processing systems, packaging machinery, and industrial manufacturing lines using 4-20 mA instrumentation. Maintenance teams and system integrators use this part for replacement, retrofit, expansion, or repair of decentralized analog signal acquisition systems.

Applications:

The TURCK BL67-2AI-I is designed for industrial applications requiring remote acquisition of analog current signals from transmitters and process instrumentation. It is commonly used with pressure transmitters, flow meters, level sensors, temperature transmitters, and process analyzers in food processing, pharmaceutical manufacturing, oil and gas facilities, and factory automation systems. The modular BL67 architecture allows installation close to the machine or process, reducing wiring requirements and simplifying maintenance procedures.
