Overview
The Allen-Bradley 1769-IF4 is a compact analog input module designed for the CompactLogix 1769 platform. This 4-channel module provides flexible analog signal acquisition with support for both current and voltage inputs, making it ideal for process monitoring, sensor integration, and industrial automation applications requiring accurate analog data.
Key Features
- Four channels configurable as differential or single-ended inputs
- Supports 0–20 mA, 4–20 mA, ±10 V, 0–10 V, 0–5 V, and 1–5 V ranges
- 14-bit resolution for both unipolar and bipolar modes
- Common mode rejection >60 dB at 50/60 Hz
- Plug-in terminal block connections for ease of installation
- Status LEDs for channel monitoring and diagnostics
Technical Specifications
Input Impedance: 220 kΩ (typical) for voltage terminals; 250 Ω for current terminals. Power Consumption: 120 mA at 5 VDC, 60 mA at 24 VDC. Operating Temperature: 0–60°C (32–140°F). Storage Temperature: −40–85°C (−40–185°F). Heat Dissipation: 2.63 W. Mounting: DIN rail or panel mount. All units are certified to C-TICK, CCC, CUL, GOST, KC, MARINE, and UL standards.
