EM4000 I/O Expansion Module
Rugged I/O Expansion and Control Module for Industrial Engine Systems
Designed for use as a standalone I/O controller or as an expansion module for MBW engine control systems.
The EM4000 I/O Expansion Module is a rugged, sealed control module designed to extend input and output capability for industrial engines and equipment control systems. It supports integration with MBW engine controllers as well as other systems capable of reading SAE J1939 messaging.
Designed for flexibility, the EM4000 may be deployed as a standalone I/O controller or used as an expansion module within a larger control system. Typical applications include system monitoring, automation, and custom I/O integration for industrial, mobile, and off-highway equipment.
The EM4000 is currently in development. Please contact MBW Technologies to discuss application requirements, integration options, or availability.
Configuration and availability subject to application requirements.
