Information About 1771-NT2
The 1771-NT2 is an N-Series analog input module from Allen-Bradley, engineered for integration into PLC-5 control systems using 1771 I/O chassis. It supports a wide range of thermocouple types as well as millivolt inputs, allowing flexible use across temperature-sensing and low-signal applications. Each channel features isolation from the backplane, improving measurement accuracy in electrically noisy industrial environments. This module communicates with the PLC-5 processor via block transfer, ensuring reliable data exchange for critical process control tasks.
Key Features:
- Eight Differential Input Channels: Supports simultaneous acquisition of up to eight thermocouple or millivolt signals.
- Wide Thermocouple Compatibility: Accepts Types B, C, E, J, K, N, R, S, and T thermocouples.
- Millivolt Signal Support: Measures low-level signals from approximately –5 mV to +55 mV.
- High Input Resolution: Provides high-resolution measurement down to microvolt-level sensitivity for precise temperature control.
- Channel-to-Backplane Isolation: Reduces electrical noise and protects system integrity in harsh environments.
- Flexible Data Formatting: Supports BCD or natural binary data formats for PLC-5 integration.
- Fast Signal Response: Typical signal delay supports timely updates for process monitoring.
- Rack-Mount Design: Installs directly into standard 1771 I/O chassis using compatible wiring arms.
- Industrial-Grade Construction: Built to meet demanding PLC-5 system reliability requirements.
The 1771-NT2 delivers the reliability and precision required for accurate temperature and low-level analog signal measurement in PLC-based process control systems.
