6ES7515-2RM02-0AB0 SIEMENS SIMATIC S7-1500R/H Redundant CPU High Availability Controller
The Siemens SIMATIC S7-1500R redundant CPU 6ES7515-2RM02-0AB0 is a redundant programmable logic controller (PLC) specifically designed for High Availability (HA) critical process control applications. As a core component of the S7-1500H series, this CPU must be used in pairs (primary/backup configuration), achieving real-time program and data mirroring through synchronous optical fiber links. In the event of hardware failure, power interruption or module failure, it can achieve a disturbure-free switching of less than 100 ms to ensure continuous production without interruption.
