What is the wetting current on PXI-2569

[errorTestMan]

As the title says,  I cannot find the spec for wetting current on that relay card. I want to use it to switch some low uA to high mA signals and was wondering what the spec was.

Hi errorTestMan,

This specification is not available through National Instruments.  NI does not actually manufacture the switches for the PXI-2569 device; another company, Tyco Electronics, does the manufacturing for these.  The part information for the switches on that device is located in the Switches Help under the Relay Replacement section for the PXI-2569.
