Frequently asked questions
Common questions about SCHNEIDER ELECTRIC Harmony from 3G Electric.
What is the difference between the Harmony GTU, GTO and SCU series?
GTU is the modular touch-panel range for flexible machine interfacing, GTO covers compact operator terminals for simpler indication and control, and SCU units act as controllers with integrated HMI functions. Selection depends on screen size, protocol support and whether local logic is required.
Can you cross-reference a discontinued Harmony terminal to a current replacement?
Yes. Send the existing part number, panel cut-out dimensions and communication type, and we will identify the closest available Harmony equivalent, including any adapter or cable changes needed to keep the machine running without re-engineering the enclosure.
Do you ship SCHNEIDER ELECTRIC Harmony terminals worldwide?
Yes. 3G Electric supplies Harmony HMIs and related spares internationally, with export documentation handled as standard. Lead time depends on the specific series and configuration, so confirm your target date when requesting a quotation.
