Information About 1771-IFE
The 1771-IFE is a ControlLogix PLC-5 analog input module that supports configurable input ranges, including ±10V DC, ±5V DC, 0–10V DC, 0–5V DC, 1–5V DC, and current ranges from 0–20 mA, 4–20 mA, and ±20 mA. It features a 12-bit resolution (plus sign on bipolar ranges) and converts analog signals into digital values stored in the PLC data table via block transfer instructions (BTR/BTW). With update times of 18 ms for 8 channels and 36 ms for 16 channels, the module provides efficient signal processing, while built-in digital filtering reduces noise for more accurate measurement. It offers Natural Binary or BCD scaling to ±9999 for flexible data handling. The module draws 750 mA from the backplane and dissipates 2.5 W, with LED indicators for RUN and FAULT status. It uses the 1771-WG wiring arm, allowing module replacement without rewiring. Designed with optoelectrical isolation and fault-response features, the 1771-IFE ensures reliable and predictable system operation in industrial automation.
Key Features:
- Channel Options: Provides 16 single-ended or 8 differential inputs, configurable per application requirements.
- Input Signal Ranges: Supports voltage ranges of ±10V, ±5V, 0–10V, 0–5V, 1–5V, and current ranges of 0–20 mA, 4–20 mA, ±20 mA.
- Resolution and Data Format: Offers 12-bit resolution with Natural Binary or BCD scaling to ±9999.
- Update Speed: Channel update times of 18 ms (8 inputs) and 36 ms (16 inputs), with additional filtering for noise suppression.
- Accuracy: Provides ±0.1% full-scale accuracy at 25 °C, ensuring precise measurements.
- Fault Handling: Includes configurable responses to communication faults for predictable and safe operation.
- Diagnostics and Indicators: Equipped with RUN (green) and FAULT (red) LEDs for real-time status monitoring.
- Installation and Wiring: Uses the 1771-WG wiring arm and requires one chassis slot, with optoelectrical isolation for protection against transients.
The 1771-IFE delivers the reliability and precision required for analog data acquisition in PLC-5 automation systems.
