Overview
The HMIYPRAM3040R1 is a Schneider Harmony iPC memory expansion module, order code HMIYPRAM3040R1, carrying 4 GB of DDR3 RAM in a PCE package for installation into HMIRS and HMIRX rack PCs. It is classified as a separate part accessory within the Harmony Industrial PC range, intended to upgrade the system memory of compatible rack-mount industrial computers.
This module adds 4 GB of DDR3 RAM to a compatible Harmony iPC rack PC, expanding the available memory for running HMI runtime applications, data logging, and multi-tab visualization screens. The RAM type is DDR3, a generation that balances speed and power draw for embedded industrial controllers. Compatibility is limited to the HMIRS and HMIRX series of rack PCs — the module is not intended for panel-mount or box-PC variants within the Harmony iPC family.
Applications
Harmony iPC memory expansions like the HMIYPRAM3040R1 are used in industrial PC-based HMI and SCADA systems deployed on production lines, packaging cells, material handling stations, and process skids where a rack-mount PC serves as the central operator interface and data concentrator.
