PXI Based Relay Modules

[Edmund.M.Williams]

I've found the list of NI PXI-based Relay switching modules, however it lists the Maximum Switching DC Current limits, but it doesn't say what the maximum current allowed after the relay is closed.  Normally we never hot switch our  relays, but after they have been switched, what is the absolute maximum current rating for each of these PXI relay modules.  (For Example:  PXI-2566, PXI-2565, PXI-2564, PXI-2568, PXI-2586, ETC., ...)

Hello Edmund,

The maximum current that a NI Switch can handle at once is called the carry current. This spec should be included in the datasheet. 

I double checked the PXI 2565 and it is listed on page 2.

If you are new to NI Switches, or have any questions about the specifications, they are explained in this article:
