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

​1.Product Overview​

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.
