KS868-A Series multiple questions - spacerunner - 03-14-2023
Hi,
just a fest questions about different A-Series ESP32 controllers:
1. Are the dry contact inputs of the KCS868-AI the same as on the KC868-A16/64/128 ? (anti-interference, ling range etc)
2. Can the dry contact inputs of KCS868-AI or KC868-A16/64/128 also be driven by external voltage, such as +5V or +12V?
3. Can the MOSFET outputs of KC868-A16/64/128 also drive +5V instead of 12V/24V?
4. Can the MOSFET outputs of KC868-A16/64/128 drive different voltages per 8-PIN-Block? For example 12V output on A1-A8, 24V output on B9-B16, 5V output on B73-B80?

1. yes, all KC868-A series board digital input is same.
2. dry contact input can work for +12v , that means logical "1", acutally >5v for logical "1" is stable.
3. sure, just every 8 channel have "Vin" , you can connect with different voltage, so that mosfet will output different voltage.
4. sure, you are right. every 8 channel mosfet use by one power supply independently.

Thank you,
so just to make sure again:
1. Driving +5V MOSFET output ist OK?
2. What is the MOSFET output voltage RANGE?
RE: KS868-A Series multiple questions - admin - 03-14-2023
1. yes, it's ok.
2. RANGE= 5v---24v DC

The mofset chip says it'll take 24VAC in the spec, any reason it won't work from the board side? maybe the led's?
I really need to drive 24vac out of this

i don't know which board model you are asking. our mosfet output for DC load, not use for AC load.

It's board KC868-A16.
It looks like the input for each set of 8 mosfet is isolated from the rest of the panel, is that correct?
If we add 24vac will it damage the board, or just see the led's not function?
RE: KS868-A Series multiple questions - admin - 02-22-2025
KC868-A16 also work with 24V power. if you want use DC24v, suggest use one power supply DC24V for board. Then every mosfet COMMON ports also connect with DC24V power.
every 8 channel msofet have one COMMON pin. so 16 channel have two COMMON pins, they are not connected in PCB. They are independent.
