Siemens 6SE6400-0EN00-0AA0 Incremental Encoder Evaluation Module

Siemen s 6SE6400-0EN00-0AA0 MICROMASTER 4 Encoder Evaluation Module is an encoder option for MICROMASTER 4 drives that provides TTL differential/HTL incremental inputs up to 300 kHz (ENCA, ENCB, ENCZ) plus an ENC-REC feedback terminal for encoder data. The module supports a 5 V supply (±5%, up to 330 mA) or 18 V non‑regulated supply (up to 140 mA), delivering about 3 W of power to its circuitry, and is designed to be wired directly to MICROMASTER 4 drives for rapid encoder evaluation. Its enclosure measures 161 mm in length, 73 mm in width, and 42 mm in depth, with IP20 protection appropriate for indoor control panels; operating temperature ranges from −10 °C to +50 °C and relative humidity up to 85% non‑condensing (storage up to 95%). This encoder option module is specifically marketed for MICROMASTER 4 systems to facilitate accurate speed and position feedback testing in applications such as conveyors, packaging machinery, and machine tools.
