D105 and sharky 775 pulse output

9 months ago in General questions • updated 9 months ago • 3

This is the output module that should give the pulse. I'm not sure how to connect this to D105.

I tried to connect like the 2-wire version, but that does not work. Do i put a resistor between the +5v and the pulse output?

Thank you

Hello Sami

Your pulse output should work with D105.

- Use Output 1 with Pulse duration: 125 ms

- In the device settings in the Counter config menu, set the filters to 0ms (or 10ms)

- The resistor is most likely needed, but you will have to select it experimentally, start with 10 kOhm, and then scale down as needed.

- General wiring diagram

- Check for pulses by increasing [TCh1] - Total Pulse 1

Thank you for your reply.

I have already set the filters to start 1ms, end 0ms. I tried both at 0 and I did get pulses then but a lot more than there actually was.

I will try the resistor next. Anything above 2.5 kOhm should be OK to try because the current can't go over 20mA, ´right?
