About the Allen-Bradley 1762-IF4

The 1762-IF4 is a MicroLogix 4 point analog input module. Its four differential bipolar inputs cover -10…+10V DC or 4…20 mA at 15 bit bipolar resolution. Typical overall accuracy is ±0.24% full scale at 25 °C and ±0.32% full scale from -20…+65 °C, with repeatability of ±0.12%. It draws up to 40 mA at 5V DC and 50 mA at 24V DC from the bus.

What is the 1762-IF4 used for?

It adds four analog inputs to a MicroLogix controller, converted by a successive approximation A/D converter. Update time is selectable at 130, 250, 290, 450 or 530 ms, and diagnostics report over range, under range or open circuit by bit. Inputs are protected to ±30V (voltage) and ±32 mA (current).
