Title: connect CMOS output to a differential input or photocoupler input
Post by: minivan on July 09, 2010, 11:20:54 AM
Hello all,
I have a PWM output 100mA, 50 Ohm from a CMOS driver. I want to connect it to the pulse input of a input/output card of a PLC. The pulse inputs are differential input (5V) and photocoupler input (5V). Any suggestion on how I should connect them? The pulse inputs to the PLC require 3 wires: pulse -, pule + and pulse input ground. The PWM output is a BNC female connector.
Thank you for your help.

Hi,

If the optocoupler can be used, it will be the easiest, as you'd just need a resistor between them.
