- 6ES7451-3AL00-0AE0 Siemens article / order number
- Module type: FM 451 positioning module
The Siemens 6ES7451-3AL00-0AE0 is a SIMATIC S7-400 FM 451 positioning module for rapid/slow traverse drive positioning. Its three channels provide dedicated control and feedback functions for coordinated position-control tasks within an S7-400 automation station.
The FM 451 provides 12 digital inputs and 12 digital outputs, with four inputs and four outputs assigned to each axis. Siemens supports symmetrical and asymmetrical incremental encoders as well as SSI absolute encoders, including RS422 input frequencies up to 1 MHz and SSI resolutions of 13 or 25 bits.
The module operates from 24 V DC and has a documented power loss of approximately 3.6 W. Engineering and replacement should preserve the S7-400 rack location, parameter set, encoder type, signal levels, axis wiring, drive interface, reference-point strategy, and configuration-package version.
The 6ES7451-3AL00-0AE0 Siemens SIMATIC S7-400 FM 451 positioning module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Spare Parts Maintenance:
6ES7451-3AL00-0AE0 is an S7-400 FM 451 three-channel positioning module for rapid/slow traverse drives. It supports incremental and SSI encoders, 12 digital inputs, 12 digital outputs, 24 V DC supply, and axis-specific parameterization; confirm rack, encoder, wiring, and configuration-package compatibility before replacement.
Retain the original configuration, firmware or project backup where applicable, and compare connectors, mounting, voltage class and environmental limits before replacement.
