Redundant and interruption-free standby controllers
Redundant Saia PCD3 controllers ensure trouble-free operation of automation systems, for example in traffic engineering, water treatment and distribution, district heating/ cooling plants and data centres.
When redundancy is critical, our PCD3.M6880 delivers.
They're designed for when reliability isn't a nice to have. It's a must have. In the event of an error, their two processors, CPU0 and CPU1, switch from active to standby CPU. No interruptions.
Dual processors add flexibility and performance
Controllers have one processor for handling the redundant program and monitoring the active PCD. A second processor handles non-redundant functions. Performance and flexibility go way up.
Smart programmable remote I/Os
Input/outputs connect to PCD3 controllers via Ethernet smart RIOs and are controlled through them. The remote I/Os are for both controllers. No need for redundant I/Os or sensors/actuators.
Time-saving engineering and commissioning
Good support from the PG5 programming tool keeps the engineering simple, while high-performance diagnostics greatly reduce the time it takes to commission and troubleshoot.
Easy system set-up in a standard Ethernet network
The redundant solutions based on Saia PCD® don't need any special network infrastructures and can be set up with standard network components. Both star and ring topologies are supported.
