Frequently asked questions
Can I use this module in a panel originally designed for 6AG1223-1PH32-2XB0?
Yes, the -4XB0 variant is a drop-in replacement with identical mechanical footprint, terminal assignment, and electrical ratings. The only change is the conformal coating, which adds environmental protection without any wiring changes.
What is the operating temperature range?
The module is rated for -40 °C to 70 °C, covering cold storage, outdoor cabinets, and high-heat industrial settings.
Does the module have short-circuit protection on the outputs?
No, short-circuit protection is not provided internally and must be supplied externally per channel or group.
What front connector does this module require?
A front connector is required but not included. It is available separately and is the same type used for other S7-1200 SM modules.
