1766-L32BXBA MicroLogix 1400 32-Point Controller 24V DC | Allen-Bradley

The Original New Allen-Bradley 1766-L32BXBA MicroLogix 1400 32-Point Controller is a compact, high-performance programmable logic controller designed for small to mid-size industrial automation applications. With a built-in LCD panel and backlight, this controller provides a higher I/O count, faster high-speed counter, and pulse train output for enhanced machine control. Featuring 32 discrete I/O points and 6 analog I/O points, it is ideal for manufacturing plants, water and wastewater treatment facilities, HVAC systems, and small process operations. The controller supports up to seven 1762 expansion I/O modules for scalable system growth.
