Innovance PLC is not taking power, what could be the possible problem?
It could be because of many reasons PLC fuse busting, no supply, high or low supply, power surge, PLC board damage.
Check power from the source link to the plc, Should check input jack power is ok if input power good then the plc power unit not working… repair it.
In case if the problem is with the PLC and not the supply then, Disassemble the plc case, find out the short circuit point. If not, isolate it then use another external power supply to power on, you can make backup and replace to new plc unit.
