Thanks in advance. I an sorry. The answer is No. You can use interposing relays with 12 VDC coil. Hope this helps.

Bhagat Amit_86 Hello,Do we have any Digital module available that works on 12V DC in any simatic PLC?Thanks in advance. What is the application. ? Hello, The Application is to read the high speed 12v DC pulse from Weighing Scale to sense the amount of material passed through During One batch Process. Inter posing Relay will not solve the purpose here since it will not be able to read such high frequency pulse & results into chattering of relay. Since , Such module does not exists , i have to look for some alternate solution.

I have asked to provide it but since it is a old system , Customer is also not sure about it's specification. I will get back to this if i got any info. Customer refuses to use relay in this case.

The CPU I use (31xC) only takes 24 VDC I believe. Same goes for the FM 350 module. Perhaps there is other series that do take different voltages. You can also put in a pulse to analoge converter. I did a quick and dirty google search and came up with a few, this isone. I have used similar devices to convert pulses from a gas counter to a 4..20mA signal, works fine.

You can generate it into your PLC instead of taking it from weighing system. I hope you are getting the mA corrosponding to the TPH from the weighing system, and "one batch finish" feedback. Implement a totalizer in the programming, and transfer the total of one batch to the particular address. Reg, Ashish
