Produkteinführung
The Allen-Bradley 1771-NT1 High Resolution Isolated Analog Input Module is a precision analog input module designed for the 1771 I/O platform with PLC-5 systems by Allen-Bradley. It is engineered to accurately acquire low-level analog signals from field devices while providing electrical isolation to prevent interference from other modules or noise in industrial environments.
The module features 8 input channels and includes cold junction compensation for thermocouple signals, ensuring precise temperature measurement across varying ambient conditions. With a typical DC signal delay von 50 ms, it provides timely and reliable analog signal processing. The isolated input design improves signal integrity, making it ideal for sensitive industrial monitoring and process automation applications.
Installed in a standard 1771 I/O chassis, the 1771-NT1 communicates with the PLC-5 processor through the system backplane. Its combination von high resolution, isolation, and stable performance makes it suitable for manufacturing automation, process control, and instrumentation applications requiring accurate analog data collection.
