Accessories

This appendix lists various National Instruments products you can use with
your NI 2501/2503 module.
• The TB-2605 terminal block has screw terminal connections for all
channels, bank commons, analog bus, and trigger signals. You can use
this card for multiplexer switching applications. The terminal block
has a temperature sensor that is used for thermocouple cold-junction
compensation.
• The TB-2606 terminal block converts the switch card to a 6x 4
two-wire matrix configuration. This terminal block creates the matrix
configuration by connecting channels (0, 6, 12, 18) (1, 7, 13, 19) …
(5, 11 , 17, 23).
• Analog bus connectors plug into TB-2605 and TB-2606 terminal
blocks. These analog bus plugs connect the analog bus of two cards
and terminate in banana plugs.
• The TBX-68S I/O connector block is a DIN rail-mounted terminal
block with screw terminal connections you can use for all channels,
bank outputs, analog bus, and trigger signals. You can use this card
for multiplexer switching applications. The terminal block has a
temperature sensor that is used for thermocouple cold-junction
compensation. This is connected to the switch card through the
SH68-68S cable.
• SH68-68S shielded 68-conductor cable connects the NI 2501/2503 to
the TBX-68S, TBX-68LP, or TBX-68LPR.
• The TBX-68LP and TBX-68LPR are low-cost termination accessories
with 68 screw terminals.
• CA-1000 is a configurable signal conditioning enclosure. It uses the
TBX-68LPR terminal block.
