Product Details
MODICON MM-PMA1-200 is an alphanumeric operator interface and HMI panel belonging to the legacy Modicon PanelMate product line. This data terminal is designed to communicate with Modicon 984 and other classic PLC controllers over Modbus serial links, delivering reliable local monitoring and manual operation for industrial automation. It features an alphanumeric display and built-in membrane keypad for operators to read live process values, modify setpoints, acknowledge alarms and send control commands directly on the production site. The unit adopts standard cabinet cutout mounting; its sealed front face provides dust and splash resistance suitable for ordinary factory environments. All screen configurations, alarm definitions and recipe parameters are saved into non-volatile memory, so stored data will not be lost after power interruption. Clear LED indicators on the front panel show power supply status and serial communication activity, helping maintenance staff quickly locate communication faults or hardware anomalies. Integrated EMI filter and surge suppression circuits protect the serial communication port against electrical noise and voltage spikes generated by inverters, contactors and heavy power equipment nearby. Users can upload and download screen projects using dedicated PanelMate configuration software and match register addresses with the host PLC. As an obsolete industrial spare part, this HMI panel is widely used for replacement and maintenance of aging automation control systems. Direct drop-in replacement retains the existing serial wiring, screen layout and PLC register mapping, cutting reconfiguration time and reducing production downtime.
