Siemens 6ES7155-6BA01-0CN0 6ES71556BA010CN0 PLC add-on module

The SIMATIC S7-200 family offers a broad spectrum of modules suitable for the most varied applications. The newly available CPU types and expansion modules enable universal automation concepts with 10 to 248 inputs/outputs. The products of the S7-200 family which are optimally matched to each other also make it easy to change and expand the automation solution in the future.
Area of application e.g.:small and special machines: Packaging, encompassing and wrapping machines .Food industry: kneading, cutting machines, Mixing .Laboratory: Lab mixer, steam ovens, vacuum pumps, suction mechanisms.
The CPUs are each offered in 5 different variants, with various connection and control voltages. The PPI interface built into all CPUs enables point-to-point connections to PG/PC, SIMATIC OP, expanded SIMATIC S7-200 and user-defined end devices (printer, bar code reader). With PG/PC or OP as master, a maximum of 31 SIMATIC S7-200 devices can be connected together. If additional inputs/outputs are required, a variety of different expansion modules is available. These are simply linked to the CPU through a connector.
