Hi

I'got a A189-1.

I 'm asking a question about voltage to trigger the function and ( position 2) or the other logical functions .

if I plug 2 out of a A155 ( trigger output or gate output ) in the A 189-1 the logical function doesn't works , is it because the A155 give a voltage about 5V

If a A 160 or  161 is use it seems to work is it because voltage is 10 Volts

if it is because of this, is ther another solution to work with the A 155  than, using a A 183-3 to amplify the voltage to 10 volts

Thank you
