1Product Description
The Allen-Bradley 1766-L32AWAA is a MicroLogix 1400 32-point controller with an AC supply and relay-output architecture. It combines controller processing, embedded digital I/O and embedded analog I/O in one compact controller body.
Its embedded I/O structure contains 24 inputs—20 digital and 4 analog—and 14 outputs—12 digital and 2 analog. The digital input path uses 120V AC, the analog input path uses 0…10V DC, and the stated digital output circuit is relay based.
The supply path is 100…240V AC at 47…63Hz. The controller can carry up to seven 1762 expansion modules, so the installed I/O system can extend from the embedded points through the expansion bus.
1766-L32AWAA is the 32-point AC-powered MicroLogix 1400 configuration. Its I/O count, analog channels, relay outputs and expansion capacity distinguish it from smaller MicroLogix controllers.
