Information About 1756-IF16

The 1756-IF16 is part of the ControlLogix I/O family from Allen-Bradley, engineered to deliver high-performance analog data acquisition. It supports input ranges of ±10V, 0–10V, 0–5V, and 0–20 mA, allowing flexible integration with a wide range of industrial sensors and transmitters. The module offers a resolution of up to 16 bits, with precise scaling values such as 320 µV/count at ±10.25V and 0.32 µA/count at 0–20.5 mA, ensuring accurate signal representation. Its conversion is based on the sigma-delta method, with selectable data formats including integer mode and IEEE 32-bit floating point. The module requires removable terminal blocks (1756-TBCH or 1756-TBS6H) for wiring, providing flexibility and ease of installation. With configurable scan times and robust noise rejection through differential wiring, the 1756-IF16 is essential for control systems requiring precise analog input processing.

Key Features:

  • Input Channels: Configurable as 16 single-ended, 8 differential, or 4 high-speed differential channels.
  • Signal Ranges: Accepts ±10V, 0–10V, 0–5V, and 0–20 mA inputs for versatile application use.
  • Resolution: High precision with up to 16-bit resolution, ensuring accurate signal measurement.
  • Conversion Method: Sigma-delta conversion for stable and reliable signal processing.
  • Data Format: Supports integer mode (left-justified, 2’s complement) and IEEE 32-bit floating point.
  • Performance: Fast scan times ranging from 5 ms to 488 ms depending on configuration.
  • Power: Consumes 150 mA at 5.1VDC and 65 mA at 24VDC, with max power dissipation of 3.9 W.
  • Integration: Designed for use with 1756-TBCH or 1756-TBS6H removable terminal blocks for simplified wiring.

The 1756-IF16 delivers the reliability and precision required for high-performance analog data acquisition in ControlLogix automation systems.

Frequently Asked Questions about 1756-IF16
Question: What is the primary function of the 1756-IF16 module?
Date Update:30/05/2025
Answer:

The 1756-IF16 is an analog input module used in ControlLogix systems. It allows a controller to receive analog voltage or current signals from field devices such as sensors. It converts these signals into digital data for use in the automation process. The module enhances system flexibility by supporting different signal types and wiring configurations.

Question: In which types of systems is the 1756-IF16 most commonly used?
Date Update:30/05/2025
Answer:

The 1756-IF16 is commonly used in process automation, manufacturing, and utility monitoring systems. Its flexibility and accuracy make it ideal for critical data acquisition. The module integrates seamlessly into ControlLogix chassis and works well with Logix controllers. It’s also used in batch control and SCADA systems.

Question: Why would someone choose Integer mode over Floating Point mode when using the 1756-IF16 module?
Date Update:30/05/2025
Answer:

Integer mode is often used in systems with limited memory or when simpler control logic is preferred. It avoids the need for floating point instructions, which can be more complex and slower on older or less capable controllers. This mode is also useful when the analog values are processed in raw format and scaled externally or in the controller code. However, it does require manual scaling, unlike Floating Point mode which simplifies integration by delivering engineering units directly.

Question: How is data formatted for use in the controller?
Date Update:30/05/2025
Answer:

The module supports both integer and IEEE 32-bit floating-point data formats. This allows users to select the best format based on application requirements. Integer mode is efficient for basic control, while floating-point supports enhanced features like alarms and linearization. The choice provides programming flexibility.

Question: Is the 1756-IF16 module still in production?
Date Update:30/05/2025
Answer:

Yes, the 1756-IF16 is still in production and available for purchase through Rockwell Automation and authorized distributors. However, users should always check the latest lifecycle status. Rockwell periodically updates product availability based on demand. Currently, the module remains supported and active.
