The ABB P72140-4-0788740 CTI21 is a temperature input module designed for industrial process control applications, specifically engineered for Hartmann & Braun systems acquired by ABB. This module is categorized as a CTI21-P Temp. Input, likely part of a legacy product line used in temperature monitoring and signal conditioning for critical industrial processes. Below is a synthesis of available information and context derived from technical references and market data:
Product Overview
The P72140-4-0788740 CTI21 is a single-channel temperature input module that converts analog signals from thermocouples or RTDs into digital data for integration with distributed control systems (DCS) or programmable logic controllers (PLCs). While specific technical details are limited, similar Hartmann & Braun modules (e.g., V17153-2121) support 4–20 mA input with galvanic isolation and Hart communication protocol compatibility, suggesting the CTI21-P may share analogous features. The module’s design emphasizes reliability in harsh environments, with applications in power generation, oil & gas, and manufacturing.
Key Features (Inferred from Related Products)
Signal Isolation: Likely includes galvanic isolation to protect against ground loops and voltage spikes, a common feature in Hartmann & Braun’s ConTrans I series 21.
Wide Signal Compatibility: Supports thermocouple types (e.g., K, J, T) and RTDs (e.g., Pt100), as seen in other legacy Hartmann & Braun modules.
Modular Design: Compatible with standardized backplanes for easy integration into existing control systems, aligning with Hartmann & Braun’s ConTrans I architecture 21.
Hart Protocol Support: Enables digital communication with smart sensors, facilitating remote configuration and diagnostics.
Industrial Durability: Designed for operation in extreme temperatures (-40°C to +70°C) and high-vibration environments, typical of ABB’s industrial-grade modules.
Application Areas
Power Generation: Monitoring turbine blade temperatures and boiler thermal processes.
Oil & Gas: Wellhead temperature sensing and refining process control.
Manufacturing: Robotic arm positioning and conveyor system temperature regulation.
Water Treatment: pH and level sensor signal conditioning in wastewater facilities.
Compatibility and Integration
While not explicitly listed in ABB’s modern S800 I/O documentation 19, the CTI21-P likely interfaces with legacy Hartmann & Braun systems or third-party PLCs via Modbus RTU or Hart protocol. Integration with ABB’s System 800xA may require adapters or gateway modules (e.g., TB8211). Users should consult ABB’s technical support for compatibility with newer platforms.
Product Status and Availability
The P72140-4-0788740 CTI21 is identified as a used/refurbished component in market listings 5, suggesting it is no longer in active production. ABB’s official documentation and product catalogs do not reference this model, indicating it may be part of a discontinued Hartmann & Braun product line. Users seeking replacements should explore ABB’s current offerings, such as the P4LQA HENF209736R0003 analog input module 1, which provides advanced features like 16-bit resolution and Profibus DP/EtherNet/IP connectivity.
Technical Support and Documentation
Manuals: No official datasheet or user manual was found in public databases. Users may need to contact ABB’s legacy support team for archived documents.
Warranty: As a discontinued product, standard warranties may not apply. Refurbished units often come with limited warranties from third-party suppliers.
Spare Parts: ABB’s global logistics network 1 offers certified replacement parts for legacy systems, though availability for the CTI21-P is uncertain.
Purchase Considerations
Third-Party Suppliers: Used units are available through platforms like eBay 5, but buyers should verify functionality and compatibility.
Alternatives: ABB’s P5EAa HENF206350R2 power supply module 2 and P4LQA HENF209736R0003 analog input module 1 provide modern equivalents with enhanced efficiency and connectivity.
