PXI-2520 Topology
Module software name: 2520/80-SPST (NISWITCH_TOPOLOGY_2520_80_SPST)
The module is composed of 80 armature non-latching SPST relays.
For certain applications, you may need to increase the default settling time.

Making a Connection
You can control the channels using the niSwitch Connect Channels VI or the niSwitch_Connect function.
For example, to close the relay of channel 2, call niSwitch_Connect(vi, "ch2", "com2"). To open the relay of channel 2, call niSwitch_Disconnect(vi, "ch2", "com2").
When scanning the module, a typical scan list entry could be ch2->com2;. This entry closes the relay between CH2 and COM2.
