779517-01
NI 9477 32-Channel, 5 V to 60 V, 8 µs Sinking Digital Output Module
The 779517-01, also known as the NI 9477, is a 32-channel sinking digital output module designed for use with CompactDAQ and CompactRIO systems. It features a broad 5 V to 60 V signal compatibility and an 8 µs update rate, making it suitable for high-speed industrial control. Each channel supports up to 1 A of continuous sinking current, with a total module capacity of 20 A. The module provides 60 VDC of continuous channel-to-ground isolation and uses an industry-standard 37-pin D-SUB connector for interface connectivity. It is built to withstand harsh industrial environments with an operating temperature range of -40 °C to 70 °C.
Temp Range-40 to 70°C
