ADLINK's PXI-7901 is a general-purpose (GP) switch module implementing 16-CH independent single-pole double-throw (SPDT) relays (1 Form C). PXI-7901 can connect one input to one output and be used as signal switching and routing for measurement system or ATE. Thanks to its high switching capacity, PXI-7901 can also be used to turn on or turn off devices such as motors, fans, heaters, and lights. The contact position of the relays can be changed either by direct software commands or by following the instructions previously stored in the on-board scan list. The scan list advances upon the trigger from external measurement devices, such as a DMM. The scan list could also advance when the scan-delay timer expires. In the PXI-7901, PXI trigger functions are supported and software programmable. Multiple modules can therefore be synchronized.

  • PXI specifications Rev. 2.1 compliant
  • 16-CH SPDT (1 Form C) nonlatching replays
  • Switching capacity: Max. count ?V 3A; Max. voltage ?V 220 VDC, 250 VAC
  • On-board 1 k-sample scan list for deterministic scanning
  • Handshaking signals for external instruments synchronization
  • Safety functions: Hardware emergency shutdown and watchdog timer from 1 ms to 420 s
  • 8 auxiliary 3.3 V/TTL digital inputs/outputs with 5 V tolerance
  • Multiple modules synchronization through PXI trigger bus and star trigger
