Product Precautions
Siemens 6ES7431-7KF00-6AA0 terminates the SM 431 analog channels while its integrated reference-temperature path supports the module's thermocouple measurement arrangement.
- Companion module: 6ES7431-7KF00-0AB0.
- Companion designation: SM 431 AI 8 x 16 bit.
- Contact method: Screw contacts.
- Pole count: 48.
The installed SIMATIC S7-400 SM 431 position links the hardware identity, interfaces and retained configuration to one controlled functional path.
Important Notice: Confirm 6ES7431-7KF00-6AA0, every connected interface and the recorded acceptance result before service release.

Siemens 6ES7431-7KF00-6AA0 Official Product Data Sheet (PDF)Siemens 6ES7431-7KF00-6AA0 Installation & Commissioning Guide (PDF)
The official excerpt preserves the applicable manufacturer pages; the field guide organizes separate model-specific readiness, connection, verification and handover checks.
SM 431 field termination
Carries the eight analog-channel conductors to the exact 48-pole module interface.
Thermocouple measurement
Provides the documented reference-temperature connection used by the SM 431.
Panel rewiring control
Preserves terminal numbering when the connector is transferred during module service.
Legacy S7-400 maintenance
Restores the approved connector and module pair without borrowing another 48-pole execution.
Apply these checks to the exact Siemens 6ES7431-7KF00-6AA0 installation before isolation, replacement or release.
1
Confirm 6ES7431-7KF00-6AA0 and companion module 6ES7431-7KF00-0AB0 before work.
2
Record all 48 terminal numbers, channel assignments and thermocouple reference connections.
3
Place the S7-400 station and affected analog loops in the approved maintenance state.
4
Isolate field circuits and verify each conductor before loosening any screw contact.
5
Inspect connector keying, terminal condition and the reference-temperature path.
6
Restore each conductor to its recorded pole and apply the approved terminal torque.
7
Seat and latch the connector without forcing it onto a different SM 431 execution.
8
Verify channel values and reference-temperature behavior before releasing 6ES7431-7KF00-6AA0.
Technical notes
Match 6ES7431-7KF00-6AA0 to the recorded SIMATIC S7-400 SM 431 position and every connected interface. Preserve the installed configuration and release only after controlled verification of 48-pole field connection and thermocouple reference-temperature coupling for SM 431.
