Siemens LA-824 Power Output Module

Hello All,

I have a customer with a number of these Siemens output modules. They are controlling a number of heaters and are blowing fuses, seemingly, at random. Has anyone used these? Know of possible issues that would affect their operation? Replacement options?

Thanks.

Part No. 6AT 1120-0BA00-0AB0 and 6AT 1120-0EA00-0AA0

I'm running into the same issues, did you find a resolution to this problem?

Thanks
