5.16 Digital Frequency Counter Module EP- 5212
Digital Counter Module EP-5212 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. Frequencys 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 μs. 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 (I
IN
).
The EP-5212 has:
• Two counter inputs 24 V DC
• Counting frequency 100 kHz max
• Digitally adjustable input filter to suppress interferences (17 filter frequencies gradually
adjustable between 3 Hz and 187 kHz)
