NI CB-37FH pin connections

Hi, can someone tell me what the swtich connections look like inside this relay? As in, if pins 20,21, and 22 are a series of NC, COM, and NO pins, which one is which? The datashee here doesnt have the info (that I can see). 


Thanks in advance,

What relay? The product page at says it's just a dumb connector block.

Forgive my fuzzy terminology. I am using the PCI 6520 switch connected to the CB-37F controlled via Labview. I called the 37F a relay because, to my understanding, it behaves like several voltage triggered switches in one block. Some of the pins on the 37F are grouped in sets of 3 (NC, COM, NO) while others are in groups of 2 (COM, NO). The path is dependent upon what values I write to the PCI 6520 lines. However, I cannot find a diagram that maps that out for me. Otherwise, how can I tell where to put my input and output wires relative to each other?

Stop referring to the dumb terminal block. The relay pins are described in the manual for the 6520 -
