NI launches relay cards for test applications in sectors such as aerospace and transportation
National Instruments
Switchblock relay cards
National Instruments (NI) has expanded its Switchblock range of high-density switching solutions for PXI systems with eight new relay cards, which are said to offer additional simultaneous connections and differential measurement capabilities for high-channel-count switching applications.
Engineers can choose from the expanded selection of NI Switchblock cards to create a custom matrix of relays to meet their specific requirements.
Designed specifically for demanding automated test systems with large numbers of channels, the Switchblock cards are claimed to provide an intuitive option for switch configuration, routing, programming and maintenance in a variety of test applications in military and aerospace and transportation as well as in general-purpose automated testing.
The set of relay cards includes two-wire switches for differential measurements and 16-row switches that give engineers an increased number of simultaneous connections for large switching applications.
Key features
- Switchblock architecture — this is intended to simplify connectivity through internal column expansion
- Expandable carrier — this accommodates up to six relay cards while occupying just four slots in a PXI chassis
- Compatibility with NI’s Switch Executive switch management software — this enables engineers to graphically configure their switch systems one relay at a time
- Included Switch Health Center software — this increases long-term system reliability by automatically running on-board diagnostics that verify relay continuity and that display relay count information
