Features:
• 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 or
• 100 RPM to 5000 RPM with 4 PPR input
• 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.
