H11l2

[artkraft]

Wired H11L2 as per diagram in manual (24v to 5v). When I test it by grounding pin #2 to simulate sink from PLC I only read .1 vdc (multimeter) to the stepper driver. shouldn't I read 5v Pin #4 to grnd.

If you check the datasheet of H11L2:

It is mentioned that the logic output is open-collector and is an inverter design. I.e. when the input LED is turned ON the output is pulled to low. If the input LED is OFF the output needs a pull up resistor to pull up to +5V.
