Problem with flex frequency input module 1794 ij2

2 posts in this topic

We are using 1794 -IJ2 Flex IO modules for taking Encoder feedbacks from Hubner- Berlin Encoders. When we are connecting one channel , the readings are good. The supply voltage from the module - to - Encoder drops to 5.6 VDC but it still works and we get the readings OK.  ( the 24vdc supply at the Power Supply end stilll measures 24VDC !!). But the moment we connect 2nd encoder  to 2nd  channel , both the readings are gone . I understand that the supply voltage 24vdc folds back inside the module ( In IJ2 ,the encoder supply has to routed through the module only) The details of Encoder Name Plate is : HUBNER - BERLIN MODEL : POG9GD  150 Incremental Encoder 9-30 VDC IP56 Current Intake : 22 mA Anybody knows solution for this?

I, witch power supply is using? You must having 180ma at 24vdc power supply. The flex i/o take 30ma. With 2 encoder at 22ma and flex at 30ma, you must having supply with a minimum of 100ma output.
