About the Allen-Bradley 1762-IF2OF2

The 1762-IF2OF2 is a MicroLogix 4 point analog combination module (selection guide 1761-SG001). It has 2 differential unipolar inputs and 2 single-ended unipolar outputs, 12 bit resolution and a typical update time of 2.5 ms. The operating range is 0…10V DC for voltage and 4…20 mA for current. Typical overall accuracy is ±0.3% full scale at 25 °C and ±0.55% full scale from -20…+65 °C.

What is the 1762-IF2OF2 used for?

It adds two analog inputs and two analog outputs to a MicroLogix controller. Inputs use a successive approximation A/D converter and outputs a resistor string D/A converter. Input diagnostics report over range, under range or open circuit by bit, and inputs are protected to ±30V (voltage) and ±32 mA (current).
