Independent Topology


1378

Both the scanning command, r2->c1;, and the immediate operation, niSwitch Connect Channels VI or the niSwitch_Connect function with parameters r2 and c1, result in the following connection:

With the independent topology, you can let NI-SWITCH determine the path between two specified channels by setting the intermediate channels as reserved for routing and using the niSwitch Connect Channels VI or the niSwitch_Connect function, or you can control individual relays using the niSwitch Relay Control VI or the niSwitch_RelayControl function.

Matrix Expansion

You can expand the module matrix using either the NI TB-2631/2631B or NI TB-2632/2632B terminal block. The terminal block you are using determines the matrix expansion procedure.

Terminal Block Toplogy (Row × Column)
NI TB-2631/2631B 1-wire 4×32, 2-wire 4×16
NI TB-2632/2632B 1-wire 8×16

Using the NI TB-2631/2631B

Use the NI TB-2631/2631B and bare wire to expand the module. You will need the following items:

  • Bare wire
  • Two or more NI TB-2631/2631B terminal blocks
  • Two or more switch modules
Terminal Reference

1378

Expanding the Module Columns

Complete the following steps to expand the module columns using an NI TB-2631/2631B terminal block.

  1. Connect one end of the bare wire to the row screw terminal on one NI TB-2631/2631B.
  2. Connect the other end of the bare wire to the corresponding row screw terminal on another NI TB-2631/2631B.
  3. (Optional) To further expand the columns, attach another bare wire to the row screw terminal you accessed in the previous step. Connect the other end of the bare wire to the corresponding row screw terminal on another NI TB-2631/2631B.
  4. Repeat the previous steps for all rows.
Expanding the Module Rows

Complete the following steps to expand the module rows using an NI TB-26312631B terminal block.

  1. Connect one end of the bare wire to a column screw terminal on one NI TB-2631/2631B.
  2. Connect the other end of the bare wire to the corresponding column screw terminal on another NI TB-2631/2631B.
  3. (Optional) To further expand the rows, attach another bare wire to the column screw terminal you accessed in the previous step. Connect the other end of the bare wire to the corresponding column screw terminal on another NI TB-2631/2631B.
  4. Repeat the previous steps for all columns.

Using the NI TB-2632/2632B

Use the NI TB-2632/2632B and bare wire to expand the module. You will need the following items:

  • Bare wire
  • Two or more NI TB-2632/2632B terminal blocks
  • Two or more switch modules

  4. Repeat the previous steps for all columns.

PXI-2530 Relay Replacement

The module uses reed relays.

Replacement Relay Part
Meder MS05-1A87-75DHR
Coto 9097-0006
National Instruments (10 matrix relays) 781450-10
Note The module has eight spare relays that can be used to replace broken relays. Removing these relays does not change the functionality of the module.

Disassemble the Module

  1. Ground yourself using a grounding strap or a ground connected to your PXI chassis.
    Note Properly grounding yourself prevents damage to your module from electrostatic discharge.
  2. Remove the four screws that secure the top and bottom daughterboards to the switch assembly. Locate the relay you want to replace.
  3. Remove the insulator and the plastic spacers that separate the daughter boards.
  4. To access the daughter boards, disconnect the PCB interconnect cable by lifting the PCB cable latch on the J1 connector.
  5. Carefully disconnect connectors J7 and J1 on the bottom daughter board from connectors J8 and J1, respectively, on the top daughter board.
  6. Refer to the top and bottom daughter board images to locate the relay you want to replace.
    1378


    1378

  7. Locate the assembly and serial number labels on the board with the relay you want to replace. White labels indicate the board was assembled using lead solder (Sn 63 Pb 37). Green labels indicate the board was assembled using lead-free solder (Sn 96.5 Ag 3.0 Cu 0.5). Lead-free assemblies have assembly numbers ending in L.

Replace the Relay

Ensure you have the following:

  • Temperature-regulated soldering iron
    • Set to 371 °C (700 °F) for lead-free solder rework
    • Set to 316 °C (600 °F) for lead solder rework
  • Solder
    • 96.5/3.0/0.5 Tin/Silver/Copper solder (flux core) for lead-free solder rework
    • 63/37 Tin/Lead solder (flux core) for lead solder rework
  • Solder wick
  • Fine pick
  • Isopropyl alcohol
  • Cotton swabs
Note NI recommends using lead-free solder for relay replacement on lead-free assemblies, and lead solder for relay replacement on lead assemblies.
Notice Do not rework lead assemblies using a lead-free work station. Lead solder from the unit could contaminate the station.
Notice If a lead-free assembly is reworked with lead solder, label the assembly to indicate this. This can prevent the same unit from being reworked later on a lead-free solder station, which could contaminate the station.

Replace the relay as you would any other through-hole part.

Reassemble the Module

Complete the Disassemble the Module steps above in reverse order to reassemble your module.

Tip Use the NI-SWITCH Switch Soft Front Panel to reset the relay count after you have replaced a failed relay. Refer to the Switch Soft Front Panel Help for more information.
