TURCK BL20-2AI-PT NI-2 3, BL20 ELECTRONIC MODULE, 6827017

Description:

The Turck BL20-2AI-PT/NI-2/3 electronic module is used in BL20 distributed I/O and temperature monitoring systems. Commonly installed in process automation skids, packaging equipment, HVAC systems, food processing machinery, and manufacturing lines requiring direct connection of RTD temperature sensors to PLC control systems. Maintenance teams, OEMs, and system integrators use this part for I/O expansion, temperature monitoring upgrades, control system retrofits, and replacement of existing analog input modules.

Applications:

The Turck BL20-2AI-PT/NI-2/3 provides two analog input channels for direct connection of Pt and Ni RTD temperature sensors within the BL20 modular I/O platform. The module is commonly used in industrial ovens, process heating systems, food and beverage production equipment, environmental chambers, and manufacturing processes requiring accurate temperature acquisition and monitoring. Its fieldbus-independent design allows integration into a wide range of industrial communication architectures while reducing wiring complexity and simplifying system expansion.
