National Instruments PXI-2567

The National Instruments PXI-2567 is a high-performance PXI Relay Driver Module designed for advanced automation and control applications. This module features 64 channels, providing flexibility in various relay control scenarios. It is compatible with both external and internal power sources, equipped with integrated 5 V and 12 V power supplies that include user-replaceable fuses for over-current protection, ensuring ease of field maintenance. Each channel of the PXI-2567 incorporates extensive protective circuitry, safeguarding against overvoltage (up to 80 V), over-current (minimum 1.5 A), and over-temperature (maximum 150 °C) conditions.

The PXI-2567 operates at a maximum speed of 150 operations per second, using an 8-pin D-SUB I/O connector for seamless integration. It allows for triggering via a front panel or PXI trigger lines 0–7, with standard input pulse width capabilities of 150 ns. Users can disable digital filtering to accommodate trigger pulses shorter than 150 ns if necessary. This module consumes 8 W at 5 V, 0.5 W at 3.3 V, and 6 W at 12 V, while offering internal drive power options of 5 V at 1.25 A and 12 V at 0.5 A.

Capable of delivering a maximum drive voltage of 50 VDC and drive current of 600 mA per channel, with a total module drive current capability of 25 A, the PXI-2567 effectively meets demanding operational requirements. It supports programmable trigger pulse widths from 1 μs to 62 μs through PXI trigger lines and features a single-channel operate time of 60 μs at 25 °C. The module has been designed for reliability, with an operating temperature range of 0 °C to 55 °C, a storage temperature range of -20 °C to 70 °C, and a relative humidity tolerance of 5% to 85%. The PXI-2567 operates using NI-SWITCH driver software and is backed by a three-year warranty. With dimensions of 8.5 x 0.8 x 5.1 inches and a weight of 8 ounces, this module is an optimal choice for various relay driver applications.
