Title: fX2424 ENCODER INTERFACING
Post by: cch1955 on September 08, 2014, 04:15:09 PM

I have an 12-24 VDC supply encoder with NPN outputs that I want to use with a Fx2424 PLC. What is the value of the internal pull up resistor on the Fx2424 inputs to 24VDC which the encoder will have to pull low?
Thanks

The inputs on Fx2424 are are pulled up to 24V DC via a 5.6K resistors.
