Характеристики Това реле се използва за сравнение на броя на импулса в минута, зададени с помощта на потенциометър и тези идващи от външен източник. Импулсите, може да идват различни източници. Най-често срещаните са:
• 24 Vdc, 2-проводни сензори
• 24 Vdc, 3- проводни, PNP сензори
• крайни изключватели, фотоелектрически превключватели и т.н.

Захранващо напрежение: 110 Vac (-15%, +10%) 50/60 Hz 220 Vac (-15%, +10%) 50/60 Hz
Description of Operation
The SX2DV100 and SX2DV103 relays are used to compare the number of
pulses per minute that are being detected to the pulses per minute setting on the
relay (using the speed threshold potentiometer and the speed range selector
switch). The pulses can be detected from a rotating shaft or from items moving
down a conveyor line.
As soon as power is applied to the relay power supply terminals, the timed
contacts and output relay contacts close and the LED indicator comes on.
To allow time for the system to attain the preset speed, a timed contact (internal
or external) is used to keep the circuit energized for a preset time period (Ti). If
the system is not up to speed by Ti, the relay will shut down the system or motor.
If the preset speed is attained by the end of Ti, the output contact will remain
closed. If the speed falls below the relay setting at any time after the Ti period is
complete, the output contacts open, shutting down the system or motor.
The LED indicator is illuminated while the output contact is closed.
Pulse Detection
The pulses can come from a number or sources. The most common are:
• 24 Vdc, 2-wire sensors
• 24 Vdc, 3-wire, PNP (sourcing) sensors
• Hard contacts (limit switches, photoelectric switches, etc.)Timed Contact Source
The Ti timed contact source is either internal or external. The internal source
uses the potentiometer on top of the relay to set Ti. The external source uses a
normally closed contact of an on-delay timer
