The 6ES7453-3AH00-0AE0 is a Siemens FM 453 positioning module for the S7-400 platform, accepting 5 V differential encoder signals (RS 422) and drawing 8.0 W from a 24 V supply. It provides 6 inputs and 4 outputs per axis, configurable for absolute encoder SSI, and requires a 48-pin front connector. RoHS compliance is documented from 21-07-17.
