In addition to the internal sensors the PCH 1026 can also be connected to both one, two and three directional external sensors like the CHB 1102/17 and the CHB 1101. When using these options, the monitor will be able to monitor tasks like nacelle differential nacelle vibrations, torsional vibrations from the output shaft of the gearbox and many other tasks needing multiple pick up locations in the wind turbine.
The PCH 1026 offers the following outputs:
up to 4 independent industrial 4-20 mA outputs,
up to 4 independent alarm relays,
1 System Failure relay,
RS-232/RS-485, CANopen, InterBUS, ProfiBUS, DeviceNET, EtherCat, Ethernet/TCP etc.
