Greetings,

I have a switch mode power supply from Weidmuller. I want to understand what the pins 12, 11, 14 are used for. They look like inputs to a relay.

I don't find any information in the manual on how they're used. The manual also doesn't state anything like contact voltage, etc.

Can someone please tell me how this is used?

My guess is that the contacts are used for power failure alarm but I don't have the manual. Do you have a link to it?

Not sure why they have NO and NC on the drawing?

The spec sheet says that those contacts connect to a relay. The relay is on when the temperature is normal and off when it is too high. It looks liks a single-pole, double-throw relay with a normally-closed contact and a normally-open one. It is NOT clear which pin connects to which relay part. Guess: when it is unpowered, the relay might be off, so that you can tell which contact is which with an ohm meter.

Under Signalling it show that the relay is a status monitoring output.

Well mine shows as a 12v 10 amp supply  (OP did not mention voltage) & the trip voltage is around 9 to 9.5V

So maybe I took a wrong turn in the internet!

But they prob are the same regardless

 

open up both datasheets ...they give a truckload of data, even screw torque!!

So it's not a relay that I can control as a switch?

NO you can't ----did you not read #4, #5, #7? 

 

What is the Vout of your supply?

If you insist to use the relay to switch something (under 1 amp)  go ahead & connect to your relay ......you can control the relay by shorting the output of the supply (perhaps with a screwdriver)  ...that is an expensive relay crying

 

My guess is that the contacts are used for power failure alarm

You knew you weren't guessing all along  cheeky
