6ES7131-4BF50-0AA0

Hello,

I have problem with 6ES7131-4BF50-0AA0 card in ET 200S  IM 151-3 PN HF v7.0. So, the problem is that I measure 24VDC in every pin of card. Also, I use power module, and  pins 2;6 is 24VDC, 3;7 (-), Aux 24VDC.

In manual, it says that Aux should have 24VDC, and the rest pins (1..8)should be contact.

Do somene has an idea what is a problem?

Best regards,

In manual, it says that Aux should have 24VDC, and the rest pins (1..8)should be contact.

 Extract from The Manual :

DIn: ( Pin 1 - Pin-8 ) Input signal, Channel n

AUX1: Sensor power supply 24 VDC (for example from power module) or potential  bus (can be used freely up to 230 VAC) 

Basically the AUX1 TBs are free TBs which you can use for distribution ( Looping ) of 24VDC. They do not have any potential by themselves. These are optional only.

Pin1 to Pin 8 are Digital Inputs. You need to send 24VDC to the field   and return signal from the contacts in the field is wired to Pin 1 to PIn-8

For more details pl see manual extract attached

Hope this helps
