RheinTacho CR Series Programmable Rotary Speed Monitors | ||||
---|---|---|---|---|
RheinTacho programmable speed monitors have numerous applications in many areas of technology, whether it be for protection of people, machines or manufactured products, to ensure that a plant operates at optimum efficiency, or for speed-dependent switching of system functions in a process.
RheinTacho programmable speed monitors continuously monitor the motion of machines and systems. They detect the signals of most speed and motion sensors. If the measured value exceeds or falls below a preset limit value, the relay is automatically switched and the alarm function connected to it is activated. Versions with analog output are also available. The alarm function can be set for overspeed monitoring with reset switching delay. Once the speed has fallen below the switchback value and the switchback time delay has expired, the relay reverts to its normal status again. The alarm function can be set for underspeed monitoring with run-up bridging. Monitoring does not start until after the start signal of the starting-bridge has de-energized and the starting bridge time has elapsed. Features
