Information About 1756-IB16

The 1756-IB16 is a ControlLogix digital input module engineered to process DC sinking signals across 16 channels within a voltage range of 10–31 VDC while maintaining stable performance in automation environments. It features basic insulation rated at 250 V continuous between input groups and the backplane, offers response times from 0.29 to 18 ms, and incorporates LED indicators for communication status, input activity, and module health. The module is designed for open-style chassis mounting, uses screw or spring-clamp terminals for adaptable wiring, and complies with global approvals including CE, CSA, UL, KC, Marine, NRTL, and RCM, ensuring compatibility with internationally deployed industrial systems.

Key Features:

  • Sixteen DC Input Channels: Supports 16 sinking digital inputs for efficient multi-signal acquisition.
  • Wide Input Voltage Range: Operates reliably from 10 to 31 VDC to accommodate varied field devices.
  • Fast Response Times: Provides configurable reaction speeds between 0.29 and 18 ms for time-critical operations.
  • Integrated Diagnostics: Displays input status, communication activity, and module health for streamlined troubleshooting.
  • Robust Isolation Design: Offers 250 V continuous basic insulation for improved group and backplane separation.
  • Flexible Wiring Options: Features screw and spring-clamp terminals for secure, adaptable installations.
  • Open-Style Architecture: Mounts directly into a ControlLogix chassis without additional enclosure.
  • Industrial Temperature Range: Operates from 0 to 60 °C under typical automation conditions.

The 1756-IB16 delivers the reliability and precision required for accurate digital signal acquisition and monitoring.

Frequently Asked Questions about 1756-IB16
Question: What is the function of the 1756-IB16 module?
Date Update:30/05/2025
Answer:

The 1756-IB16 is a digital DC input module used in ControlLogix systems. It reads the status of up to 16 discrete DC input signals from field devices. These signals can come from sensors, switches, and other binary devices. The module then transfers these signals to the controller for processing. It is ideal for high-speed and reliable digital input monitoring in industrial environments.

Question: What kind of signals are compatible with the 1756-IB16?
Date Update:30/05/2025
Answer:

This module accepts 12–24VDC sinking input signals. It detects logical HIGH and LOW states based on the voltage thresholds. The module can detect ON states starting from 10V DC and OFF states below 5V DC. Each channel draws around 2 to 10 mA depending on voltage. Proper signal conditioning ensures optimal detection.

Question: How is the 1756-IB16 powered and what is its consumption?
Date Update:30/05/2025
Answer:

The module draws 120 mA at 5.1V DC and 2 mA at 24V DC from the ControlLogix backplane. The total power dissipation is up to 5.1W at 60°C. Its thermal dissipation is 21.1 BTU/hr. This makes it energy-efficient while providing fast input monitoring. Ensure adequate ventilation within the panel for thermal management.

Question: What are the physical dimensions of the 1756-IB16 module?
Date Update:30/05/2025
Answer:

While the exact dimensions are not explicitly listed in the documentation, the module fits into a standard ControlLogix chassis slot, which typically measures approximately 1.38 in (35 mm) in width. It is designed for compact installation alongside other modules. The enclosure is open-style and fits securely in the chassis frame. The physical size ensures space efficiency in control panels.

Question: Is the 1756-IB16 module still being manufactured?
Date Update:30/05/2025
Answer:

Yes, the 1756-IB16 module is currently in production and available from Allen-Bradley. It remains a standard product in the ControlLogix family. The module is widely supported and compatible with current Rockwell platforms. Replacement parts and support documentation are readily accessible. It is actively used in both new and legacy systems.
