Schneider Modicon Quantum CPU

This Modicon Quantum CPU has been designed to manage the Hot Standby functionality for the programmable logic controllers within the Schneider Electric Quantum series. To protect the application programme from inadvertent changes during operation, it is stored in a battery backed internal RAM. The processor is easy to use and features an LCD display to access diagnostics, access certain configuration parameters and starting and stopping the CPU. The processor battery is easy to access and service as it is located on the front of the unit and can be changed whilst the CPU is in run mode. The Hot Standby system is compatible with Unity Pro™ XLS software, and provides the CPU with the high level of availability required by the critical process applications.
