Good morning,

i need to know the maximum input voltages of the opto-isolated inputs of the MOD-IO Module. I want to check some signals in a car (12 - 14 volt dc).

Thanks in advance,
Mathias

Hey MADze,

According to the relays' datasheet: (12-14)VDC should fit.

Hello Lub,

thanks for the fast replay. But i didnĀ“t mean the relays, i mean the input of the photocouplers.

Regards,
Mathias

Oops, Mathias skipped the first post :)

The opto-couplers are H11A817s by FAIRCHILD semiconductors. 15V input is the maximum input according to our schematic.

Hello Lub,

thanks for that information, cool so i can use the MOD-IO without any periphial (resistors, etc.) in my car (12 - 14v dc).

Issue done :-)

Hi,

What is the minimal voltage on the opto-coupled input ?

Thanks,
Franck
