SIMATIC S7-400 – FM 451 Positioning Module – Siemens Function Modules

$ 1,330.41

SKU 6ES7451-3AL00-0AE0 Category

The FM 451 three-channel positioning module handles the adjustment of mechanical axes in the case of rapid-traverse and creep-speed drives. The module is intended for the positioning of adjusting and setup axes, preferably with standard motors, controlled via contactors or frequency converters.
