About the Siemens 6ES7392-1AJ00-0AA0

The Siemens 6ES7392-1AJ00-0AA0 is the 20-pole screw-terminal front connector for 20-pin S7-300 signal modules, such as the 16-channel SM 321 and SM 322 and the SM 331 analog input module. Siemens's data sheet gives conductor cross-sections of 0.14 to 0.75 mm² (AWG 24 to 19). Siemens's data sheet marks it as a spare part.

What is the 6ES7392-1AJ00-0AA0 used for?

It is the wiring side of an S7-300 I/O module: the field cables land on it, and it plugs onto the module's front.

Lifecycle and successor

Discontinued: product cancellation (Siemens SiePortal), spare part only.

Before you order

What to photograph or confirm so the right unit is quoted.

Check the pole count on the module (20-pin) and the terminal type (screw).
