How do I use this? Is there a Chinese version of the instructions? Is it meant for mere monitoring, or does it have other uses?
It’s a speed protection system, similar to Protech 203 ……
All turbomachines use Brown controllers for overspeed protection; the first one is a configuration card, and the subsequent ones are used to monitor the speed. There is likely also a relay voting card that wasn’t captured in the photos. The interfaces at the bottom can be connected to a PLC via Profibus DP.
