Overview

Product overview

Key product information and technical features.

The PXIe-2569 provides 100 independent SPST Form A electromechanical relays in the PXI ecosystem, using a PXI Express bus connection. Its normally open relay configuration provides individual switched paths rather than a fixed multiplexer arrangement.

Software-programmable operation includes a 32,000-step scan list for deterministic scanning. The module has a scan rate of 145 cycles/s and a switch bandwidth of 20 MHz. Consult the NI specifications for the operating conditions and load limits associated with these ratings.

  • 100 channels implemented with 100 independent relays.
  • SPST open (Form A) electromechanical relay configuration.
  • PXI Express bus interface.
  • Maximum switching voltage of 100 V AC and 100 V DC, with maximum DC switching current of 1 A.
  • 20 MHz switch bandwidth and 145 cycles/s scan rate.
  • Software-programmable operation with a 32,000-step scan list.
