PROFIBUS DP master for ET200S stations
The 6ES7138-4HA00-0AB0 is a PROFIBUS DP master interface module for the ET200S distributed I/O system, designed to sit on an IM151-7 CPU or IM151-8 PN/DP. It provides a single DP master connection via a 9-pin D-sub socket, supporting transmission rates up to 12 Mbit/s with a maximum shielded cable length of 100 m. Only one such master module can be used per CPU, so plan the PROFIBUS segment count accordingly. Dimensions are 35 mm wide, 75 mm deep, 119.5 mm high — a standard ET200S slot footprint.
