The Beran 768 Condition Monitoring System is an optimised solution for smaller turbines such as those used in Hydroelectric and Gas Pumping Installations. In addition, an alternative configuration utilising a multiplexed input option is ideal for auxiliary plant applications.

Designed around the Beran 766, the 768 System compliments the modular design of the Beran range. The system utilises the same Beran MS Windows Client Software, which provides full PC control of the Condition Monitoring System.

The system can monitor up to 4 tacho signals, 8 AC signals (32 Multiplexed), 16 local DC channels (up to 256 remote), 8 digital channels and has 8 alarm relay outputs. The multiplexed variant allows up to 4 plant items to be monitored.
