FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is the SC-2062 a matrix switch?

NI identifies the SC-2062 as an accessory with eight independent SPDT nonlatching electromechanical relays, rather than a matrix switch.

Which cable connects the SC-2062 to a TBX-68T or CB-68T?

NI specifies the NB7 ribbon cable for connecting SC-206X digital signal conditioning boards to these terminal blocks.

Can the SC-2062 connect to the SC-2056?

Yes. NI documents connection to J8 on the SC-2056. J8 shares digital signals with J4–J7, so those signals must not be double-driven.

What do part numbers 776336-02 and 776336-12 identify?

NI lists 776336-02 as the SC-2062 with a 26-conductor 0.2 m cable and 776336-12 as the configuration with a 0.4 m cable. The catalog record does not identify which configuration applies or establish that a cable is included.
