Rotational Speed Monitor
Signal conditioning for characteristical value
The input signals are scaled before processing. The characteritical value is proportional to the
speed, i.e. the input frequency divided by the number of theeth of the pulse wheel configured
with the configuration software.
Range adjustment
Maximum measuring range
Maximum speed
Maximum number of teeth
Current output − characteristical value
The calculation of the characteristical value and its evaluation depends on the function
determined during configuration.
Current output 1 − I1+ / I1−
Current output 2 − I2+ / I2−

z20 (+) / b20 (−) galvanically isolated
0...20 mA or 4...20 mA, depending on configuration
in the 4...20 mA mode the output con be set to 0 mA
in case of a fault. This function is activated during
configuration.
