1762-IF2OF2 - 2CH 4-20mA IO Isolated - Industrial Small-System Rugged Din-Rail Module

The Allen-Bradley 1762-IF2OF2 MicroLogix™ Hybrid Analog Module combines 2-channel analog inputs and 2-channel analog outputs in a single-slot form factor for compact automation systems. Designed for MicroLogix 1100/1400 controllers, it features 12-bit resolution on both I/O types, supporting ±10V DC voltage and 4-20mA current ranges. The polycarbonate housing (IP30-rated) withstands industrial debris and operates reliably from -20°C to +65°C. Integrated screw terminals simplify field wiring, while configurable filtering and software-selectable ranges via RSLogix 500® enable flexible integration into diverse processes without external signal conditioning.
