- Page 5 Topologies PXI-2564 8-DPST Topology Module software name: 2564/8-DPST (NISWITCH_TOPOLOGY_2564_8_DPST) The module is composed of 16 electromechanical armature latching SPST relays. For certain applications, you may need to increase the default settling time. Note Switching inductive loads (for example, motors and solenoids) can produce high voltage transients in excess of the module's rated voltage.

For certain applications, you may need to increase the default settling time.
- Page 7 When scanning the module, a typical scan list entry could be ch2->com2;. This entry closes the relay between CH2 and COM2. PXI-2564 Relay Replacement The module uses electromechanical armature relays. Refer to the following table for information about ordering replacement relays.
- Page 8 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.
- Page 9 PXI-2564 Features Complete the following sets of steps to disassemble your module and replace a failed relay. 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.

Green labels indicate the board was assembled using lead-free solder ■ (Sn 96.5Ag 3.0Cu 0.5). Lead-free assemblies have assembly numbers ending in L.
- Page 11 Do not use flux remover to clean the board after relay replacement. 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.
