Information About 1771-NT2
The 1771-NT2 is a high-resolution, isolated analog input module designed for use with Allen-Bradley’s PLC-5/1771 I/O systems. It provides eight differential analog input channels capable of reading thermocouples or low-level millivolt signals with exceptional precision. With 16-bit resolution, channel-to-backplane isolation, and robust environmental ratings, the 1771-NT2 is built to ensure accurate and noise-immune signal acquisition in industrial automation and process control systems.
Key Features:
- Module Type: Isolated Analog Input Module for PLC-5 systems
- Input Channels: 8 differential channels
- Input Types: Thermocouples (Types B, C, E, J, K, N, R, S, T), millivolt signals (–5.5 mV to +56 mV)
- Resolution: 16-bit (approx. 65,000 counts; ~0.9 µV/bit)
- Accuracy: ±0.01% full scale
- Update Rate: 25 ms typical per channel
- Input Bandwidth: 9 Hz
- Isolation: Full channel-to-backplane isolation for noise immunity
- Common-Mode Rejection: Up to 150 dB at 60 Hz
- Power Requirements: 1.5 A at 5 V DC from the backplane
- Heat Dissipation: Approximately 5 W
- Operating Temperature: 0 to 60 °C
- Storage Temperature: –40 to 85 °C
- Humidity: 5–95% non-condensing
- Shock/Vibration Resistance: Designed to meet industrial IEC specs
- Mounting: Standard 1771 I/O chassis
- Communication: Supports block transfer for data exchange with PLC-5
- Termination: Compatible with remote termination panels such as 1771-RTP1
- Status: Discontinued product (available via legacy support channels)
The 1771-NT2 is ideal for applications requiring precise, isolated measurement of temperature or low-level analog signals. Its high accuracy, fast response, and rugged design make it a trusted solution in legacy process control installations. Though now discontinued, it remains in use across various industries and is supported through modernization services and replacement strategies.
