Description
The 777661-01, 777661-06, 777661-07 are part numbers for a Digital I/O Device designed to interface with USB connections. This device is capable of handling Four 24-bit Programmable Peripheral Interfaces (PPIs) and includes Three 8-bit Sub Ports. It offers a transfer rate of Up to 60 S/s, making it suitable for a variety of applications.
The device boasts 96 bi-directional 5 V static I/O Lines, allowing for a wide range of input and output possibilities. Additionally, it can deliver an Output Signal Current of 0.5A maximum at +5 VDC specifically from pin-49 and pin-99. It also has a Current Drive capacity of 2.5 mA per channel, culminating in a total of 240 mA.
Despite its powerful performance, the device has a reasonable Power Requirement, needing Up to 12 W at 9–30 VDC from an external source, and a USB Current Requirement of 220 mA typical, 500 mA maximum at 4.40–5.25 VDC. It utilizes a 100-pin female, 0.050 series D-type Connector for physical connections.
Users have the flexibility to configure the Power-up State manually, choosing between a High or Low wake-up state. This device is compatible with NI-DAQ software, enhancing its utility with easy integration into existing systems. With Physical Dimensions of 9.0 x 5.7 in, it fits comfortably in a variety of setups. It operates within a temperature range of 0° to 70° C and can be stored from –55° to 150° C. Its resilience is further highlighted by its ability to function in relative humidity levels of 5% to 90%, non-condensing.
