[Diy_efi] RE:photocoupler?

[Tony Petroski]

oh, AC input is i think just terminology associated with the fact that
the INPUTS have LED diodes going in both directions. i.e. say pin 1 &
pin 2 are connected with diode in direction pin 1 & pin 2. Then
corresponding to the AC input, another diode then follows pin 2 to pin
1. 

This is the only difference to the Fairchild H11L1. May i ask, the
following... 

If i intend to use such a photocoupler inline with the injector
circuit which is 12V & nonpolar, will the Fairchild H11L1 work as the
LED diode only goes in one direction ?

Can someone further add to the terminology of the word 'nonpolar'? I
do understand, non-polar means that the device doesnt have any
preferences or requirements to which terminal is anode or cathode.




thanks
