NI 9485 National Instruments C Series 8-Channel SSR Solid-State Relay Output Module

NI 9485 is NI C Series 8-channel solid-state relay digital output module, compatible with CompactRIO and CompactDAQ chassis. Each channel supports max 60 VDC /30 Vrms switching, 750 mA per channel when all 8 channels active, screw terminal connection. It is widely used in industrial test benches, automated actuators, valve control and relay switching systems

Description

NI 9485 belongs to NI C Series I/O hardware family, using solid-state relay (SSR) without mechanical contact, longer service life compared with electromechanical relay modules. It has 8 normally-open SSR output channels, supports sourcing or sinking output mode. Max switching voltage: 60 VDC, 30 Vrms. Max current 0.75A per channel for full 8-channel operation; up to 1.2A per channel if only 4 channels used. Typical close time 9ms, maximum switching rate 1Hz at 90% duty cycle.

This module adopts screw terminal block for field wiring. It provides channel-to-channel isolation of 60 VDC continuous and channel-to-earth isolation withstand voltage up to 2300 Vrms, protecting backplane and controller from field circuit interference and surge damage. It is programmed via LabVIEW for on/off control of solenoid valves, small contactors, indicators and low-power actuators. Front panel LED indicators display each channel status for quick on-site troubleshooting. Operating temperature range -40℃ ~ +70℃, suitable for rugged industrial environments.

Built-in protection includes overcurrent protection, surge protection and ESD protection. IP20 protection grade for cabinet installation.

NI 9485 is mature NI C Series spare module. When the original module fails, replacing it with identical NI 9485 can reuse existing CompactRIO / CompactDAQ chassis, wiring and LabVIEW project without redevelopment. Technicians insert module into chassis, configure digital output tasks and test channel on-off switching, so the actuator control system resumes operation and reduces downtime.

Before shipment, every NI 9485 undergoes comprehensive functional inspection including power-on self-test, each SSR channel switching test, isolation check and LED indicator verification. All products come with 12-month warranty. Our automation technical team provides remote support for module installation, wiring guidance and LabVIEW configuration. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, NI 9485 is reliable spare SSR relay output module for NI CompactRIO / CompactDAQ systems. It restores solid-state relay on-off control for field actuators, extends service life of test and automation assets and avoids high-cost whole system renovation.
