Module EP-5212
Figure 140: Connection Diagram EP-5212
The digital counter module EP-5212 can read frequency of one square-wave signal (1
channel) from one or two external sensors with a maximum input frequency of 100 kHz.
Frequencies to be counted are applied to channel CH0 and/or channel CH1, the
measurement will be started via control word 1 and 2 respectively. Measuring cycles can be
defined in
μ
s. The longer the measuring cycle the more exactly the measurement.
A status LED is assigned to each channel. The module electronics supply the connected
sensors with power from the input voltage path (IIN).
The EP-5212 has:
•
Two counter inputs 24Vdc
•
Counting frequency 100 kHz max
•
Digitally adjustable input filter to suppress interferences (17 filter frequencies
gradually adjustable between 3 Hz and 187 kHz)
