Can anyone explain how I connect these two cards together? De K6714 has an 12 volt output I can use with de K8061 but when I look at the following picture this isn’t possible…
Why is it needed to optically isolate the voltage inputs? (actually I totally don’t understand this diagram… No GND connected, 12volt to k8061, no CLAMP???)
2nd question: how do I safely connect the K6714 to the digital outputs and analog outputs? (i need more than 8 digital outputs)
My excues for these huge questions…But when i’m going to experiment with the card I will contribute to this forum…
The diagram is correct. K8061 features open collectors. +12V is taken from K8061. Clamp is not needed, as triac card is not an inductive load. Optical isolation is needed because triac card is connected to AC grid.
K6714: do not mount transistor arrays, mount wire jumpers instead (as explained in manual)
Connect K6714 GND to K8061 GND, connect in 1…8 of K6714 to out 1…8 of K8061. Clamp is not used as K6714 is equipped with suppressor diodes.
Actually I built the k6714 yesterday and the card has an output of 16 volt!!! I’m reluctant to connect it to the K8061.
I have a question about the transistor array, I searched the internet for some info but i don’t understand it completely. I know its just an array of darlington transistors, but what i know of transistors is that they will make the emitter high when you put a voltage to the base. Like the manual said, i connected the GND to the relay input, but nothing happened. Anyhow, when I use the dipswitches everything works just fine.
So how do the transistor arrays work in the k6714?
You do not need the transistor array to connect it to the K8061. The K8061 features open collector outputs, so you need to replace the transistor array with wire jumpers, as indicated in the manual.
Ahh, I see now. Thank you. Now I just need to get my K8061 working again. I somehow manage to short something and the 5v voltage regulator is heating up such that by 30 seconds after power-on the output voltage drops below the point where the CPU will run.
