1762-IF4 Analog Input Module – Allen‑Bradley MicroLogix 1200
4 differential inputs for current (4‑20 mA) or voltage (±10 VDC). Compact, bus‑powered module for MicroLogix 1100/1200/1400 controllers. Delta‑Sigma converter with 15‑bit resolution ensures accurate signal acquisition in harsh industrial environments.
Product Description
The 1762‑IF4 is a four‑channel analog input module from Rockwell Automation’s MicroLogix family. It accepts voltage (–10.5…+10.5V DC) and current (4…20 mA, full scale –21…+21 mA) signals. Each channel is individually configurable via DIP switches. The module communicates over the 1762 bus using a flat ribbon cable and requires only 5‑24V DC from the controller.
Designed for DIN rail or panel mounting, it supports 2‑, 3‑, or 4‑wire transmitters. The field‑upgradable flash OS keeps firmware current without hardware replacement. With IP20 rating, it suits dry, non‑hazardous locations (overvoltage Category II).
