DP Profibus DP

Each CPU requires a Micro Memory Card (MMC). Programming may be carried out using the Step 7 Lite software (stock no. 539-1755).

Need an easy way to monitor and regulate your automated industrial process? Choose this PLC CPU from Siemens. It's the brains behind your PLC, carrying out instructions from the computer programme that keeps your equipment running smoothly. Thanks to an impressive 28 inputs (24 digital plus four analogue), this unit can work with an extensive range of operational feedback. With 18 outputs (16 digital plus two analogue), it can also respond quickly and effectively to the data it receives. The modular design means you can accessorise this adaptable device with complementary products from the S7-300 series to build a system that suits your needs. You'll find CPUs like this one used in automotive manufacturing and robotics.
