Information About 1756-IF4FXOF2F
The 1756-IF4FXOF2F is part of Rockwell Automation’s ControlLogix series, designed for applications requiring fast and accurate analog signal processing. It supports input ranges of ±10V, 0–10V, 0–5V, and 0–20 mA with 14-bit resolution, while the outputs provide ±10V or 0–20 mA with up to 14-bit resolution. The module incorporates overrange and underrange detection, open circuit monitoring, and short-circuit protection to ensure safe operation. Compatible with 1756 ControlLogix chassis, it connects using 1756-TBCH or 1756-TBS6H removable terminal blocks and features synchronized channel scanning across multiple modules for coordinated system performance.
Key Features
- Combination Module: Provides four high-speed differential inputs and two high-speed analog outputs.
- Fast Performance: Sub-millisecond scan times with synchronized sampling for precise control.
- Wide Input Range: Accepts ±10V, 0–10V, 0–5V, and 0–20 mA signals with 14-bit resolution.
- High-Resolution Outputs: Offers ±10V or 0–20 mA output with up to 14-bit conversion accuracy.
- Protective Features: Includes overrange/underrange indication, short-circuit protection, and open-circuit detection.
- Output Conversion: Utilizes R-ladder DAC conversion method with no missing codes.
- Calibration & Stability: ±1 LSB repeatability with a recommended calibration interval of 12 months.
- Application Versatility: Suitable for monitoring variables such as flow, pressure, level, and temperature, and for controlling actuators, drives, valves, and converters.
The 1756-IF4FXOF2F delivers the reliability and precision required for advanced process control and high-speed analog signal handling in industrial automation systems.
