Agilent Technologies MI4-111-KE1-001 Operator Panel

Moeller MI4-111-KE1-001 Text Operator Panel is a compact, text-based human–machine interface for the MI4 control family (Klockner Moeller, now Eaton). This operator panel provides local input and status display for Moeller automation installations and is designed to be mounted in control enclosures, powered from a 24 V DC supply. The unit's electrical characteristics include a 24 V DC input and a typical current draw of about 0.25 A, enabling integration into small, panel-mounted control stations without heavy wiring. The MI4-111-KE1-001 variant denotes the specific configuration of the MI4 text operator panels; when sourcing a replacement, verify compatibility with your existing MI4 hardware and the KE1-001 option set. In practice, these panels are encountered as replacement parts for legacy Moeller/Moeller-Eaton installations and are commonly found through distributors offering new-old-stock or refurbished units. They are used in industrial automation environments where simple, text-based prompts and keypad input are sufficient for local control tasks, such as start/stop commands, mode selection, and basic process monitoring, in conjunction with the main controller that handles logic and communications. This model is typically cataloged under Klockner Moeller operator panels and is relevant for maintenance or upgrade projects on older MI4-series systems.
