About the Allen-Bradley 1762-IQ16

The 1762-IQ16 is a MicroLogix 16 point digital input module. Its 16 inputs on 2 commons take 24V DC sink/source, with operating ranges of 10…26.4V DC and 10…30V DC. On and off delays are 8.0 ms maximum. It draws up to 70 mA at 5V DC (0.35 W) from the bus and dissipates up to 5.4 total watts at 30V or 4.3 total watts at 26.4V.

What is the 1762-IQ16 used for?

It adds 16 DC inputs to a MicroLogix controller. Inputs 0…7 form Group 1 and inputs 8…15 Group 2, isolated from each other. Group to backplane isolation is verified by a dielectric test of 1200V AC for 1 s or 1697V DC for 1 s, with a 75V DC working voltage (IEC Class 2 reinforced insulation).
