1762-IF4 Allen Bradley MicroLogix 4 Channel Analog Input Module
The Allen-Bradley 1762-IF4 is a compact, high-precision 4-channel analog input module designed for the MicroLogix series of programmable logic controllers (PLCs). It supports both voltage (-10 to 10V DC) and current (4-20mA, with full-scale range of -21 to 21mA) signals, enabling seamless integration into industrial automation systems for data acquisition and process control. Ideal for monitoring temperature, pressure, flow, and other analog variables, this module delivers reliable performance in demanding environments.
Key Features
High-Accuracy Signal Processing
16-Bit Resolution: Ensures precise measurement of analog signals with binary two's complement data format for accurate scaling
Delta-Sigma (Δ-Σ) Converter: Delivers high-speed sampling (1000Hz) and low noise, critical for stable process control
Differential Inputs: 4 channels of differential (bipolar) inputs support flexible sensor configurations (2-wire, 3-wire, or 4-wire transmitters)
Robust Isolation & Compatibility
Channel-to-Backplane Isolation: 1500V AC isolation between channels and the system backplane protects against electrical interference
MicroLogix Compatibility: Works with MicroLogix 1100 (max 4 expansion modules), 1200 (max 6 expansion modules), and 1400 (max 7 expansion modules) PLCs
Flexible Installation & Configuration
DIN Rail/Panel Mounting: Compact design (90mm H × 87mm D × 40mm W) allows easy installation in control cabinets
DIP Switch Configuration: Simple signal type selection (voltage/current) via onboard DIP switches
LED Status Indicators: Per-channel LEDs provide real-time feedback on signal presence and module health
Reliable Operation
Overvoltage Protection: Circuitry complies with Overvoltage Category II standards for safe operation in industrial environments
