Dear Expert,

hello, Expert.

I have questions about the output voltage of ET200eco PN.

When output signal is off, the output voltage is measured about 3V.

this is why? Is there something settings?

Please see the attached screenshot.

Best Regards,
Min Su Kang

hi Min Su,

what kind of module do you have?

If someone should help you, you need to describe more details, about what kind of module you have, how it is parametrized and wired. 

ET200eco PN is a product-family. Please give us an order no. beginning with 6ES714x-xxxxx-xxxx

regards,

I also have this problem with using ET200ECO PN 8DO DC24V/1,3A 8xM12

without PLC output signal the output of X1 to X4 have 12Vdc, 9Vdc on X5-X8.....

 hi LLC,

where do you measure this voltages?

Are the outputs set?

have a look in the techical data of this module. there you can see the rated value of the load voltage 2L+ 24VDC

TD

Supply voltage

Rated value (DC)                                       24 V

permissible range, lower limit (DC)        20.4 V

permissible range, upper limit (DC)       28.8 V

Reverse polarity protection                      Yes

Load voltage 2L+

● Rated value (DC)                                    24 V

● permissible range, lower limit (DC)     20.4 V

● permissible range, upper limit (DC)     28.8 V

● Reverse polarity protection                   Yes

 hope this helps,

regards

Hi mopS04,

thanks for the reply

I measure X03 pin1 and pin3 (supply voltage) is 24Vdc

X1 to X4 without PLC output, I measure between pin3 and pin4, it got 12Vdc

X1 to X4 with PLC output, I measure between pin3 and pin4, it got 24Vdc

X1 to X4 without PLC output PE against pin3 0Vdc

X1 to X4 without PLC output PE against pin4 12Vdc

Hi,

I have the same problem, How was it resolved? Thanks.

Hello,

I have the same issue with module 6ES7 142-6BH00-0AB0:

When the PLC output is SET, the digital output pin voltage with respect to 1M or 2M is 12VDC.

When the PLC output is ON, the digital output pin voltage with respect to 1M or 2M is 24VDC.

How did you resolve this issue?

Thanks.
