The NI-9485 is a product from National Instruments, categorized under C Series Digital I/O. It comes with part numbers 779600-01 and 779600-02. This module is designed to provide 8 SSR Solid State Relay output channels, capable of handling a maximum switching voltage of 60 VDC and 30 Vrms.
For applications requiring high current, the NI-9485 offers a maximum switching current of 1.2 A per channel for up to 4 channels and 750 mA per channel when all 8 channels are in use. Notably, it features channel-to-channel isolation, enhancing its reliability and performance in complex systems.
The relay open time is a swift 0.5 ms, with a close time of 9.0 ms, ensuring quick response times for dynamic applications. In active mode, the resistance is as low as 200 mΩ, and the off-stage leakage is minimal at 30 μA.
Connection is facilitated through a screw terminal connector, accommodating a wide range of wire gauges from 30 AWG to 14 AWG. The required strip length for wire installation is 0.24 inches, with a torque range specified between 0.22 N · m to 0.25 N · m for secure connections.
When active, the NI-9485 consumes approximately 500 mW of power, dropping to a mere 5 mW in sleep mode, showcasing its efficiency. It weighs 5.1 oz and is designed to operate within a temperature range of -40 °C to 70 °C, making it suitable for a variety of environments and applications.
