We are using ISO1212 component for 24V digital output to 5V digital output level translation.
For this application we would be using EJ2889 module. EJ2889 is a 16-channel digital output (24 V DC, 0.5 A output) module from Beckhoff and it is a ground switching module, which means when the Digital Output channel (DO_x) is "ON" it sinks the FGND. So the Channel state would be "LOW".
when the Digital Output channel (DO_x) is "OFF", the corresponding channel would be connected with +24V supply. So the Channel state would be "HIGH".
For your reference, I have attached the Schematics.
We have a technical Query on ISO1212:
- When the Digital output is "HIGH" (Connected with +24V pull up resistor), will there be any impact on the Output side (OUT_1 & OUT_2) due to the leakage current from the Digital output module.
Note: EJ2889 module has an Internal pull up resistor connected with +24V supply in all the output channels.
