31 channel, 2 A, SPST PXI relay module

The PXI‑2568 is A universal switching module with an independent single pole single throw (SPST) Form A armature relay. Each relay is a non-latched relay with extremely low on-resistance and low thermal offset. The PXI‑2568 is fully software programmable. By effectively combining high voltage/current capability and relay density, the switch module is ideal for automatic test equipment (ATE) loads or for controlling heaters, lights and fans.

National Instruments PXI-2568 relay module

The National Instruments PXI 2568 (Part number: 778572-68) is A widely available 31-channel relay module that features a free SPST (Type A) armature relay. Each relay has a locking function with low on-resistance and low thermal offset. The NI PXI 2568 can switch current up to 2 A at 30 VAC/ 30 VDC. The PXI 2568 effectively couples voltage/current capacity and relay density, making it perfect for automating test equipment (ATE) loads or controlling heaters, lights and fans. This model can extend throughput in automated test applications by utilizing scanning. Scan increases throughput by downloading up to 32,000 lists connected to the switch and using events (triggers) to loop through the list without interference from the host processor. Pairing the PXI-2568 with an instrument, such as the NI PXI-4070 61 ⁄2 bit FlexDMM, emits a trigger key after each estimate to achieve the most efficient scanning. The device is equipped with a 62-pin male DSUB I/O connector. It has a power requirement of 6 W at 5 V and 2.5 W at 3.3 V. All NI PXI SWITCH modules come with NI-Switch, an IVI compliant driver that provides full utility for all switch modules.

Repeater power supply refers to the power supply that provides power to the repeater device. A repeater is a network device used to extend the transmission distance of a signal in a network and increase the strength of the signal.

The repeater power supply usually uses DC power supply, and its voltage and current depend on the requirements of the repeater equipment. Power to the repeater can be provided via a power adapter, battery, solar panel, etc.

When selecting the repeater power supply, it is necessary to consider the stability, reliability, efficiency and other factors of the power supply to ensure that the repeater equipment can work normally. At the same time, it is also necessary to consider the size, weight, cost and other factors of the power supply to adapt to different application scenarios.
