What this part is – and the rating that decides fit
The 6AG1124-1JC01-4AX0 is a Siemens SIPLUS HMI panel with an operating range of -20 °C to 60 °C. It covers MPI, MODBUS, TCP/IP, WinCC, LOGO!, and HTML/HTTP for web-based interfaces. Operator input is via 26 hardwired function keys and sliders — no touchscreen calibration drift. It includes flash memory for recipe storage, alarm handling, and arrays for data logging. Buzzer and speaker onboard for audible alerts.
Where this gets specified
This SIPLUS variant is specified for refrigerated areas, sunny factory roofs, or near drying ovens. Its -20 °C to 60 °C range allows operation where standard HMIs would fail. The housing accepts the same cut-out as the 6ES7 family, so no panel modification is needed. Confirm gland plate clearance for high-temperature cables.
