Pulse evaluation systems with cULus... support the worldwide use of evaluation systems that have been tried and tested for many years. They are suitable for simple speed monitoring for underspeed or blockage on elevators, conveyors and ventilation systems, as overspeed monitors in wind power systems or load monitoring on hoists. Slip and synchronous monitors protect hoists from misalignment, conveyor belts and slipping clutches from wear and destruction. Direction monitors signal wrong directions of rotation, e.g. of twin pumps. Frequency-to-current converters convert pulse sequences into analogue signals, 0 /4...20 mA or 0...10 V. The configurable M18 compact speed monitors are suitable for a wide range of applications and provide ease of monitoring. A wide-range power supply of 90...260 V AC in combination with the cULus approval supports the worldwide use of the evaluation systems.
