Hi

Thx

Dear Packmers,

could you please explain what you exactly mean by the "related K-Relay Numbers" and what you need to for.

The Relais on the 2503-Board are only numbered from K0...K31.

Dear Packmers,

Here you can find the Pinouts and the Hardware diagram for the NI PXI-2503.

But what is missing in this Specification is the Relais Number (K0..31) or is it in the chinese Part ?

[OlegS]

Dear Packmers,

where are you seeing this Relais Numbers (K0..31)?

When I'm looking into my MAX into the config of the PXIe-2503 I am seeing this:

There are the same channel numbers (ch1..ch23) like in the Specs.

So please give me more information.

I see the K0..31 Numbering on the Hardware-Board of the 2503. I need to replace some Relais- o.k. I could measure them out, but easier would be a reference to the Channels.

Dear Packmers,

usually the deployment of broken Relays is done by our RMA service because if you do it on your own the warranty becomes invalid.

And this is why this information is not in the Specs because we don't expect the customer to do any modifications on the HW by his own.

I would command you to RMA the HW and get the Relays replaced and the HW tested.

Thats strange, because for the more difficult to repair 2532 an Instruction for repair the card by customer is available.

So it looks, i have to measure it out.

Thanks

Finaly I've make the work to measure the relays by hand:

K0..23 =CH0..23

K24 = BC01

K25 = BC23

K26 = BC02

K27 = CJS

K28 = 1WIRE

K29 = HISELECT

K30 = AB0

K31 = AB1
