GE IC693MDL748 Series 90-30 DC Voltage Output Module
Product Overview
The GE IC693MDL748 is a discrete output module from the Series 90-30 family, designed to deliver reliable DC voltage control in industrial automation systems. This 8-point output module supports 24VDC or 48VDC positive logic outputs, allowing it to source current to external loads such as solenoids, indicators, and motor starters. Each of the 8 output points can supply up to 0.5A of current.
Equipped with LED indicators for point status and a blown fuse alert, the module simplifies diagnostics and maintenance. It is designed for installation in any I/O slot of a 5 or 10-slot baseplate within an IC693 Series PLC system.
