The 6AG1322-1FH00-7AA0: A green FSG LED confirms the per-group fuse is healthy; red means blown. The module also reports the event over the backplane via a diagnostics function (fuse blown or missing load voltage). That means the PLC can log the fault and the maintenance team knows which group dropped without climbing the ladder. The SF (group error) red LED lights up too. Expect a response time of 300 ms maximum for the alarm.
The module is rated for continuous operation from -40 °C up to 70 °C. At 70 °C the output current is derated to 1 A per channel.
No — the 6AG1511 is a SIPLUS S7-1500 CPU, not a digital output module. The mechanical footprint, bus connector, and wiring are completely different. You cannot substitute them without redesigning the panel.
