FX2N All inputs on unit producing 24v

hello, has anybody seen this before, the unit I am programming is producing 24v out of the input side. there I no connection to the input terminals either?

cannot understand why this is happening, never seen this issue appear before.

A little vague - what unit?

24V with reference to what?

Are the input led's on?

Sink or source inputs?

A little more information and we can give a little more information. :)

Have you connected the input "S/S" (SINK/SOURCE)to anything ?

Connect it to the negative reference if you want to source 24VDC to the inputs to activate them.

Connetc it to the positive reference if want to sink the inputs to 0VDC to activate them.

It is normal for you to be able to measure 24V with a DMM to the common on you inputs (assuming it is a sinking unit, some models are predetermined, others it is dictated by what is connected to the S/S terminal). This 24Volts has a high resistance and wouldn't actually power anything. When you connect the common to it the input will come on.
