The DMS is an economical shaft speed switch, typically used to detect a slowdown on conveyors, fans, blowers and other machinery where a reduction in shaft speed rotation could adversely affect plant operations.
The unit is switch selectable for NPN, PNP, mag sensor and logic level sensor inputs. Two models offer setpoint ranges from 5 - 5000 RPM. The setpoints are adjustable via two (2) 25-turn potentiometers located under the housing cover. Both setpoints are switch selectable for over- or under-speed operation. A viewable LED indicates the relay status for easy trouble shooting.
