Hi!
I have an old printing press where I would like to monitor the circuit breakers if there are tripped or not!
I have 7 different locations on the machine and with approximately 35 circuit breakers on each one, having a medium distance of 10m of each other.
The problem is that the printers can start the press and do not know if one CB is tripped or not, but in the mean time we have costs with paper, ink, etc.
So, I’m thinking in using the following solution:
- Siemens S7-1200 with HMI console to display the error message. One Input for each location
- Remote board to connect one phase L1 of the output of each CB, witch energises a individual relay. Making the interface between 240Vac and the 24Vdc from the PLC. If one CB is tripped the relay will not latch, then the remote board will not send the 24Vdc to the input of the PLC
Is there a more simple way to do this? Do you know another way to make the interface between the 240Vac from the CB to the 24Vdc of the PLC? Another brand of PLC can do it better?
Thanks in advance,
Bruno
