Siemens 6ES7516-2PN00-0AB0

The CPU 1516PRO-2 PN serves as a central processing unit for the ET 200pro system, offering a work memory capacity of 1 MB for program storage and 5 MB for data management. It includes two PROFINET interfaces: one for IRT with a built-in 3-port switch and another for RT. The unit achieves a bit performance of 10 ns, enabling efficient processing of control tasks.

This model is designed with an IP65/67 degree of protection, ensuring its suitability for harsh environments. It requires a SIMATIC memory card for operation, and a connection module is necessary for integration. The CPU operates on a supply voltage of 24 V DC, with permissible limits ranging from 20.4 V to 28.8 V. The maximum input current is 0.4 A, and it features rail and wall mounting options.

With a compact form factor of 135 mm in width, 130 mm in height, and 65 mm in depth, the CPU weighs approximately 614 g. It supports a variety of protocols, including MODBUS and PROFINET IO, and can connect to up to 1,000 distributed I/O devices across various communication modules. This makes it well-suited for complex automation tasks in industrial settings.
