Product Introduction
The Allen Bradley 1769-OA8 CompactLogix AC Solid-State Output Module is a reliable and compact output module designed for the CompactLogix family of controllers. It provides 8 AC solid-state output points, organized in two groups of 4 outputs, for switching AC loads such as motors, solenoids, lights, and other industrial devices. The module is optimized for automation systems that require fast switching, high reliability, and minimal mechanical wear.
Operating within a voltage range of 85–265 VAC and a frequency of 47–63 Hz, the module is suitable for various industrial AC environments. Its fast turn-on/turn-off delay of 0.5 cycles ensures precise control of AC loads. The module draws a maximum bus current of 145 mA at +5 VDC (1.125 W), consuming minimal power from the CompactLogix backplane, and has a heat dissipation of 2.12 W, maintaining stable performance during continuous operation.
The 1769-OA8 is ideal for modern industrial applications requiring precise AC control, including OEM machinery, process automation, and distributed control systems. Its solid-state design ensures high reliability, low maintenance, and consistent operation under typical industrial conditions.
