The Muirhead® Pulse Width Modulation (PWM) Sense Switch Control can be programmed in the field to switch at any given PWM duty cycle set point.
This exceptionally useful device can monitor the duty cycle percentage and provides a set of changeover outputs (both positive), one below the pre-set programmed value and one above.
An example application would see it monitoring the duty cycle on a proportional retarder control valve using PWM control. The 5534 could be set to bring on an external light to indicate when the retarder is being heavily applied.
