When you're outfitting a control panel, the first fork in the road is whether you need a complete operator interface or a replacement component for one that's already installed. That's the real decision between these two very different PLC HMI options.
Quick Verdict
If you're starting a new build or upgrading to an integrated PC-based HMI, the ProFace PS5000 IPC + PS5001 HMI + PwrSup package delivers the full setup at $2,499.95. If you just need to restore a worn-out keypad on an existing Siemens HMI, the Siemens KTP700 Membrane Keypad + Touchpad repair kit is a much lower-priced fix at $181.39.
Comparison at a Glance
| Product | Price | Price Bar | Type | Condition | Origin |
|---|---|---|---|---|---|

| Siemens KTP700 Membrane Keypad + Touchpad | $181.39 | PLC | Used | China |
Where the ProFace PS5000 Wins
The ProFace PS5000 package is the complete automation workstation. It bundles the ProFace PS5000 industrial PC, the PS5001 HMI, a power supply, SSD, mounting hardware, and a software and documentation kit. The description notes that software such as Rockwell Software and IXXAT Canbus is pre-installed, so it's ready to integrate into a control system that depends on those protocols. With a $2,499.95 price tag, this is for projects where you need a whole new operator interface rather than a spare part.
Where the Siemens KTP700 Repair Kit Wins
If your existing KTP700 HMI still functions but the membrane keypad or touchpad is physically worn or unresponsive, this repair kit targets exactly that problem. At $181.39, it's a very different price point from the ProFace bundle, and it lets you keep your existing panel and wiring in service. It's a used item, but the scope is narrow: a replacement keypad/touchpad, not a full HMI.
Product Notes
NEW! ProFace PS5000 IPC + PS5001 HMI + PwrSup, Programmed, Software, CAN, Etc
This listing is the whole package for an automation workstation. It includes the ProFace PS5000 industrial PC, the PS5001 HMI, a power supply, SSD, mounting hardware, and a software and documentation kit. As a new open-box item, it has been powered up only for listing photos and operation verification. The pre-installed software includes Rockwell Software and IXXAT Canbus, which makes it particularly useful for environments built around those tools. Choose this if you need a complete, ready-to-wire operator interface solution and you want to avoid sourcing components separately. The limitation is the open-box condition, which means it doesn't arrive in original packaging.
Siemens KTP700 Membrane Keypad + Touchpad 6AV2123-2GB03-0AX0 HMI Repair Kit
This is a targeted fix for a damaged or worn membrane keypad and touchpad on a Siemens KTP700 HMI. It lets you keep your existing display and controller in place, avoiding a full unit replacement. The part number 6AV2123-2GB03-0AX0 identifies it as a repair kit for the KTP700. It's a used part, and its type is listed as PLC, reflecting its role in a PLC/HMI control system. It's the right choice if the rest of your HMI is functional and you only need to restore the touch interface. The limitation is that it doesn't include the HMI itself, so it won't help if your display or controller is also failing.
Final Choice by Use Case
Pick the ProFace PS5000 IPC + PS5001 HMI + PwrSup when you're building a new panel, replacing an aging HMI, or need a complete PC-based operator interface with pre-installed software. Pick the Siemens KTP700 Membrane Keypad + Touchpad when you already have a working KTP700 HMI and just need to restore the keypad/touchpad to keep production running.
