Core Hardware Specifications
  • Channels: 8 independently isolated analog inputs (differential/single-ended)
  • Signal Types: Independently configurable per channel:
    • Voltage: ±10V, 0–10V, 0–5V, 1–5V
    • Current: 0–20mA, 4–20mA (2-wire/4-wire transmitters)
  • Resolution: 24-bit Σ-Δ ADC
  • Isolation: 300V DC between channels and backplane
  • Scan Time: ≤ 8 ms (8-channel full scan, typical)
  • Accuracy: ±0.15% of full scale (25°C typical)
  • Power Supply: Backplane 5.1V DC / 200 mA; 24V DC / 400 mA (current source)
  • Power Consumption: Voltage mode 4.6 W; Current source mode 10.6 W
Dimensions and Logistics
  • Body Dimensions: ControlLogix single-slot width
  • Packaging Dimensions: Approximately 15 × 10 × 8 cm
  • Volumetric Weight: Approximately 0.0012 m³
  • Shipping Weight: 0.5 kg gross weight
Firmware 2.012 Specifications
Version and Compatibility
  • Applicable Series: Only 1756-IF8I Series B (Series A supports up to firmware 1.x)
  • Release Date: Approximately 2021–2022
  • AOP Requirements: Add-On Profile v40.12.23 or later for Studio 5000 / RSLogix 5000
  • Controller Compatibility: ControlLogix 5580/5570/5560 Series
Important Firmware Notice
Known Issue: Firmware 2.012 has a connection timeout error that may cause module assertion failure. The module records diagnostic data and enters a fault state (OK light remains red), preventing controller connection.

Recovery Method: Power cycle the module (RIUP hot-swapping is ineffective) to restore normal operation.

Fixed Version: This issue is resolved in version 2.013 and later.
Functional Capabilities
  • Open-circuit detection (current input only, <2.5mA trigger at 4–20mA)
  • Digital filtering, process alarm, and open-circuit detection
  • Does not support HART communication (acquires 4–20mA DC component only)
  • Requires external 24V DC power supply for transmitters
Software and Environmental Specifications
  • Programming Software: Studio 5000 / RSLogix 5000
  • Firmware Upgrade Tool: ControlFlash / ControlFlashPlus
  • Certifications: CE, UL, cULus, CSA
