Electro-Sensors, Inc. Economical Shaft Speed Switch DMS5000

Economical Shaft Speed Switch • Works with remote/external pulse frequency output sensor (NPN, PNP, Mag Pick-up and TTL) • Over-speed or under-speed configuration • 5 RPM to 100 RPM with 8 PPR input (DMS100) • 100 RPM to 5000 RPM with 4 PPR input (DMS5000) • 2 SPDT relay outputs • DIN rail mounting simplifies installation • 115, 230 VAC (50-60 Hz) and 12, 24 VDC power options 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. The DMS is 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.
