Technical Specification | DAZIC® — ROTOGUARD IV SPEED SWITCHS
Electronic Speed Switch
DAZIC® The RotoGuard IV speed switchs device for sensing the reduction, increase, or loss in rotational motion associated with many types of moving equipment. The unit can detect changes in motion between 1 and 400 RPM and provide a change of state, or alarm, when a variation in operating speed occurs. The RotoGuard® IV may be direct coupled to another shaft or driven with a belt or chain.
The RotoGuard® IV is designed with an optical encoder and multi-toothed interrupter wheel to transform the rotation of the input shaft to voltage pulses. A change of input speed from the calibrated running speed results in the output relay changing state. A startup alarm delay feature allows time for the monitored equipment to come up to speed before the unit will alarm. An adjustable alarm delay feature eliminates nuisance alarms during erratic motion
Features::
- UL Listed
- Universal Voltage Input
- Solid state electronics
- Alarm Delay: 0-60 seconds
- Startup Delay: 0-120 seconds
- Models available with NEMA 4/5 Rating (weatherproof and dust tight) or NEMA 7/9 Rating (Explosion Proof [EP models cannot exceed 100 RPM.])
- If an alarm indication is desired when speed falls to 90% of operating speed, rotate one switch to “9” and the other to “0”.
