PXI Relay Module
Relay
PXI Relay Modules consist of multiple independent relays, such as single-pole single-throw (SPST), single-pole double-throw (SPDT), and double-pole double-throw (DPDT) relays. PXI Relay Modules use a variety of relay types, including electromechanical armature relays, reed relays, field-effect transistor (FET) relays, and solid-state relays, each with their own benefits, allowing you to choose a set of relays that fit your requirements. To program the relays, you can use the IVI-compliant NI-SWITCH driver software, complete with help documentation, example programs, and a soft front panel application for interactive control. For intelligent management of complex switch systems, NI Switch Executive provides additional software tools to help you design, build, and deploy your switching system.
