This document lists specifications for the PXI-2533 256-crosspoint, SSR matrix. All specifications are subject to change without notice. Visit ni.com/manuals for the most current specifications.
Specifications characterize the warranted performance of the instrument under the stated operating conditions. Data in this document are Specifications unless otherwise noted.
Typical Specifications are specifications met by the majority of the instrument under the stated operating conditions and are tested at 23 °C ambient temperature. Typical specifications are not warranted.
All voltages are specified in DC, ACpk, or a combination unless otherwise specified.

Switching inductive loads (for example, motors and solenoids) can produce high voltage transients in excess of the module’s rated voltage. Without additional protection, these transients can interfere with module operation and impact relay life. For more information about transient suppression, visit ni.com/info and enter the Info Code induct.
