The NI SC-2062 is an 8-channel electromechanical relay module designed to extend the switching capabilities of National Instruments DAQ devices. Each of the eight SPDT relays independently switches loads up to 6 A at 30 VDC or 250 Vrms, with normally open, normally closed, and common terminals accessible via screw terminals. The module connects directly to compatible NI DAQ instruments through a 26-pin ribbon-cable connector, typically using SC-205x series cable adapters, and requires no additional software beyond the connected DAQ board’s driver suite.

– Key Features
• Eight independent SPDT relays for isolated load switching
• Screw-terminal connections rated for power switching applications
• Optionally mounts in 19-inch rack chassis alongside SC-205x series devices
• Workbench and rack-mount configurations supported
• Part numbers 776336-02 and 776336-12 include integrated SC-205X cables (0.2 m and 0.4 m respectively)
– Typical Applications
• High-power signal routing in automated test systems
• Load switching where DAQ digital output ratings are insufficient
• Multi-channel relay control in measurement and control instrumentation
– Compatibility & Integration
The SC-2062 integrates with NI E Series and 60xxE DAQ devices, as well as the 6503 (DIO-24), 6533 (DIO-32HS), and 6508 (DIO-96) modules via their 8-bit digital ports. When paired with SC-205x series adapters, the module supports IBM PC/XT/AT, Macintosh II, and IBM PS/2 architectures.
