The NI 9485 8-channel solid-state relay (SSR) digital output module is used on the National Instruments C Series platform. The NI 9485 is designed to operate at a temperature range of –40 to 70 °C. The specifications provided in the NI 9485 Operating Instructions
are guaranteed across this full temperature range. However, when used at lower temperatures, the NI 9485 SSRs can operate at higher currents and/or faster switching speeds than indicated in the published specifications. This document provides information about the maximum allowable currents and switching rates across all operating temperatures.
