National Instruments Corporation NI 9477, 32-CH 60 V, 8 US, SINKING DIGITAL OUT, CONFORMAL COAT
The NI 9477 (PN: 780174-01) is a 32-channel, 5 V to 60 V, sinking digital output module with conformal coating, designed for use with NI CompactDAQ and CompactRIO systems. It provides 32 individually isolated channels for digital output, supporting a voltage range from 5 V to 60 V and a maximum output current of 1 A per channel. The module features a 8 µs update rate and is suitable for driving relays, solenoids, and other industrial actuators. The conformal coating enhances reliability in harsh environments by protecting against moisture, dust, and chemical contaminants. The NI 9477 is hot-swappable and offers channel-to-channel isolation for robust operation in demanding applications.
