Siemens SIMATIC PLC Base Unit - 6ES72121HE400XB0

The SIMATIC S7-1200, CPU 1212C, is a compact CPU with DC/DC/relay, onboard I/O including 8 DI 24 V DC, 6 DO relay 2 A, and 2 AI 0-10 V DC. It's powered by a DC supply of 20.4-28.8V DC, with a program/data memory of 75 KB. The SIMATIC S7-1200 Basic Controller is flexible with a wide variety of communication options, making it the first choice for implementing automation tasks flexibly and efficiently in the mid to low performance range. The CPUs are scalable in their performance and available for different input voltages, and with transistor or relay outputs. Safety versions are also available.

In addition to the existing integrated inputs and outputs, the compact CPUs can be expanded directly on the device or with a wide variety of signal and communication modules to adapt them to your exact requirements. HMI devices can also be connected via the integrated Ethernet interface. The memory of the CPU can be expanded by means of a memory card, and the PLC is configured using the STEP 7 Basic software in the TIA Portal.

The micro PLC has a wide range of networking options via various communication standards by means of integrated functions such as PROFINET, Modbus, or add-on modules like IO-Link, AS-i, etc. Thus, it offers maximum flexibility in the topology and when setting up the networks.

Thanks to its compact design, the fields of application for the S7-1200 are very varied and extend from simple packaging machines and heating systems to its use as a subordinate control system in larger plants. Its compact design, modular structure, and integrated IOs help to save space in the control cabinet.

The STEP7 configuration software is integrated into the TIA Portal, which can therefore rely on shared data storage, a uniform operating concept, and integrated communication services for all components of a system. This means lower configuration costs and faster commissioning.
