Description
The NI PXI-2585 is identified by its part number 778572-85 and falls under the category of PXI Switches. This model is a 10-Channel High-Current Multiplexer (MUX) designed for versatile applications requiring high-current switching capabilities.
With a current rating of 12 A, it is suitable for handling significant power demands. The configuration type of this device is a 1-Wire, 10×1 Multiplexer, providing flexibility in connecting a single input/output to any one of the ten channels.
The maximum switching voltage is rated at 300 V channel-to-channel and 300 V channel-to-ground, classified under Measurement Category II. This ensures safe operation for most high-voltage applications. Moreover, it can handle a maximum switching power (AC) of 3 kVA (up to 60 Hz) per channel, making it robust for various electrical environments.
Equipped with electromechanical single-side stable relays featuring silver-nickel contact material, the PXI-2585 offers reliable performance. The actuation time is impressively swift, with a maximum of 15.4 milliseconds, ensuring quick switching operations.
Its life expectancy is notable, with up to 1 × 107 cycles mechanically and 1 × 105 cycles electrically at 30 V DC, 10 A DC resistive load. For a 12 A DC resistive load at the same voltage, it can reach 3 × 104 cycles, demonstrating durability in demanding conditions.
The I/O connector is a Positronic GMCT series plug, including 20 positions, which offers a reliable and secure connection. This device is engineered in a one-slot, 3 U PXI module form factor, with dimensions measuring
