DO801 supply showing short circuit due to 230 vac connection
Accidently the supply connection of 230 VAC instead of 24 VDC were done with one DO801 module. Now it is showing short circuit, what is the cause? Is it because of protection circuit?
It is repairable?

Most probably you have had a smoke or fire after connection of 230VAC to 24VDC connector. As per block diagram of DO801, this connector provides 24VDC to the output drives.
I suppose all of them are blown and recommend replacement of the module. In some cases it could disturb Modulebus as well.
Replacement with the new module will be cheaper than repair (if repair is available at all for that type of modules)
