SpeedSys T10/SpeedSys T11

\n

The SpeedSys T10 and T11 are 1-channel monitoring, transmitting and switching systems for rotational speed measurement. They convert speed into highly accurate analog signals for further processing and provide relay functions for alarm and trip or shutdown. The T10 features two configurable relays, \"\"while the T11 includes an integrated display and one configurable relay.

SpeedSys T20

\n

The SpeedSys T20 is a 2-channel monitoring, transmitting and switching system with 4 configurable relays. The T20 offers more speed monitoring functions than the T10, including: speed acceleration, creep, zero speed, reverse rotation, dynamic sensors monitoring, and multi-channel integrated trip functions. The system also features a redundant power supply and redundant sensor inputs.
