Siemens TOP connect assemblies reference this connector type for prepared single-wire solutions used with S7-400 modules.
| Check point | Verification | Procurement note |
|---|---|---|
| Module interface | Confirm the installed S7-400 signal module uses a 48-pole front connector. | Do not infer compatibility from the S7-400 family name alone. |
| Terminal method | Verify screw contacts are required. | Crimp and other connector variants use different order numbers. |
| Mechanical coding | Compare connector keying and module position before installation. | Incorrect coding can prevent correct seating. |
| Wiring records | Check terminal assignment and conductor labels against the cabinet drawings. | Retain a verified wiring schedule before replacement. |
Siemens lists 6ES7492-1AL00-0AA0 as PM300:Active Product; product phase-out starts 01.10.2025. Confirm current regional availability and the installed module interface before procurement.
