The 6AG1223-1PH32-4XB0: The relay outputs handle up to 250 V AC or 30 V DC, with lamp loads up to 200 W AC or 30 W DC. No internal short-circuit protection—provide external fusing per channel or group. Diagnostics and alarms are built in, covering wire break, load supply, and channel status. The 45 mm wide footprint fits compact enclosures.
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.
The module is rated for -40 °C to 70 °C, covering cold storage, outdoor cabinets, and high-heat industrial settings.
No, short-circuit protection is not provided internally and must be supplied externally per channel or group.
A front connector is required but not included. It is available separately and is the same type used for other S7-1200 SM modules.
