Product Description: Siemens 6ES7151-1AA02-0AB0

The Siemens 6ES7151-1AA02-0AB0 is a standard PROFIBUS DP interface module (IM151-1) for the ET 200S distributed I/O system. It provides reliable DPV0/DPV1 communication at up to 12 Mbit/s and supports a data volume of 128 bytes for both input and output. Up to 63 downstream I/O, power, electronic or motor-starter modules can be connected. Bus interfacing is via a 9-pin Sub-D connector and includes integrated termination.
