Dear Siemens,

Can you tell me the voltage tolerance / threshold on the input to a LOGO 12/24RCE 8DI 12/24VDC 4DO v8.4. ie the threshohold between a high and a low.

I have had some ramdom emails being sent from my BM saying an event triggered by one of the inputs has happened when clearly it hasn't.

I'm trying to eliminate things to get to the cause and wonder if its voltage fluctuations on the input?

Thanks in advance
