National Instruments PCI-6503 digital I/O device

The National Instruments PCI-6503 (Part number: 777690-01) board is a parallel digital I/O interface that can be used with PCI bus computers. Equipped with a 1 x 82C55A PPI chip, this 24-bit model is designed to operate in one-way, handshake or two-way mode and can issue interrupt requests to your personal computer. The digital input/output lines of this model are accessible via a male connector (50 pins).

The NI PCI-6503 is a completely jump-free and switch-free data acquisition board. At startup, all of its resources are allocated completely automatically. Therefore, users do not have to manually set the base address or interrupt level. With this board, users can operate their personal computer as a complete digital I/O solution and system controller in a variety of applications such as production testing, laboratory testing and process control. With NI-DAQ software, the NI PCI-6503 offers excellent transfer rates of up to 50 KB per second (maximum) and provides a constant sustainable rate (typical) of 1 to 10 bytes per second. The device is equipped with a 50-pin male ribbon cable I/O connector. The PCI-6503 has 24 bidirectional digital I/ O channels with TTL compatibility.

The NI PCI-6503 is designed to receive 2.2V (minimum) and 5.3V (maximum) input logic high voltages. This mode operates at − 0.3V (minimum) and 0.8V (maximum). It produces A 1.0 A (Max) output signal via pin 49 (+5 V). With this board, users can consume 2.5 mA (typical value) output current. The board requires 400 mA to operate at +5 VDC (±5%) power, and the power provided by the I/O connector remains around +4.65 to +5.25 V.

In addition, it weighs 1.9 ounces and measures 4.8 x 3.7 inches. In the physical dimension. The recommended operating temperature range for NI equipment is 0 °C to 55 °C, the storage temperature range is -20 °C to 70 °C, and the operating random vibration is 0.31 grms (5 to 500 Hz). The non-operating random vibration is 2.5 grms (5 to 500 Hz).
