AEG AS-B838-032 B838 Modicon Output Module

Description:

The AEG AS-B838-032 B838 MODICON Output Module is an industrial PLC output module used in MODICON 800-series control systems to convert PLC logic signals into discrete 24 VDC outputs for controlling field devices. Commonly installed in industrial automation systems, machine control panels, and manufacturing equipment where multiple digital outputs are required to drive relays, solenoids, indicators, and actuators. Maintenance teams and system integrators use this module for PLC system expansion, replacement of failed I/O modules, and support of legacy MODICON control architectures.

Applications:

The AEG AS-B838-032 Output Module is commonly used in industrial automation systems, factory control panels, material handling equipment, and OEM machinery where reliable multi-channel digital output control is required. It is designed for use in MODICON 800-series PLC systems controlling devices such as motor starters, valves, pilot lights, and relay interfaces in continuous-duty industrial environments.
