National Instruments 778572-67 PXI Relay Module

The part number 778572-67 from National Instruments is the identifying part number for the PXI-2567 PXI Relay Module. This module has 64-channel relays with a maximum drive current per channel being 600 mA. This relay module has a maximum drive voltage of 50 V DC with an internal drive power of 5 V at 1.25 A or 12 V at 0.5 A. The module has a single channel operation time of 60 μs meaning it takes only 60 μs to perform its requested operation. 

The module has 8 addressable trigger lines which are memory addressable and can be programmed via compatible software. The pulse width for the trigger control signal should be 150 ns wide for it to be considered as a control signal. The output also has 8 trigger lines from addresses 0 to 7 with trigger control signal being programmable from 1 μs to 62 μs. 

This relay module has a 78-pin D-SUB I/O connector installed on it. The PXI power requirement is 8 watts at 5 volts or 0.5 watts at 3.3 volts. This module has dimensions of 21.6 × 2.0 × 13.0 cm (8.5 × 0.8 × 5.1 in.) and weighs approximately 220 grams. The operating temperature of this module is 0 °C to 55 °C and the storage temperature is -20 °C to 70 °C. The module has a humidity rating of 5% to 85%, is noncondensing, and has a pollution degree level of 2. The module must be mounted 2000 meters maximum above sea level. 

This module has an operation shock of 30 g peak, half-sine, 11 ms pulse (Tested in accordance with IEC 60068-2-27), and operational vibration rating of 5 Hz to 500 Hz, 0.3 grms. The non-operation vibration rating of the 778572-67 PXI Relay Module is 5 Hz to 500 Hz, 2.4 grms (Tested in accordance with IEC 60068-2-64). This module does not come with an internal protection class certification and must be kept in a dry and clean place to prevent dust and moisture from damaging the internals and affecting its performance.
