Function and features
The DC0103 monitors rotational speeds (mainly with regard to under-
speed).
It takes pulses from external pulse pick-ups and switches the output relay
depending on the set switch point max (D
max
) and switch point min (D
min
).
The output relay
- is energised when the maximum
rotational speed is reached
- is de-energised when the speed
is below the min. rotational
speed.
•
Setting range: 30 ... 25 000 pulses /min.
•
Intelligent switch point setting while machine is in operation (“teach-in”).
