What is the relay type of NI 2503?

[mqwhale]

"User Manual" of NI 2503 says "the NI 2503 is an armature relay switch card ".What's the meaning of "armature"? Is it the same as "Electromechanica"?

And "electromagnetic".

Are they the same type relay?

Hi mqwhale,

Yes armature type means the same as electromechanical.
