Product Introduction

Siemens 6ES7451-3AL00-0AE0 is an FM 451 three-channel positioning function module for the SIMATIC S7-400 automation system. It positions rapid/slow traverse drives and provides four digital motor-control outputs per channel for rapid traverse, creep, travel right, and travel left. The module accepts symmetrical or asymmetrical incremental encoders and SSI absolute encoders for displacement measurement. With twelve digital inputs, twelve digital outputs, 5 V and 24 V encoder supplies, galvanic isolation, and a 48-pin front-connector interface, 6ES7451-3AL00-0AE0 integrates controlled positioning into compatible S7-400 machines and material-handling systems.
