Description
The product with a Part Number 186676B-04 falls under the category of PXI Switches. Specifically, it is model SCXI-1192, an advanced and highly capable device designed for various applications. This model is described as an 8 Channel SPDT, 18 GHz, 50 Ohm, RF Relay Module, making it suitable for high-frequency applications up to 18 GHz.
It features 8 SPDT relays, each providing 2 channels, which enhances its versatility in connecting and controlling different RF signals within your setup. The module can handle a maximum voltage of 30 V and supports a maximum current of 2 A at 30 V, ensuring reliable performance across a range of operating conditions.
An Auto-Detect Option is available, ensuring seamless integration and ease of use within compatible systems. It is specifically tailored for compatibility with the SCXI-2000 chassis for auto-detect functionality but also offers the flexibility to connect to an NI instrument for other chassis types, broadening its applicability.
The module utilizes 24 screw-on SMA jacks for its connectors, ensuring secure and reliable connections for your RF signals. It employs latching electromechanical relays with gold plate contact material, which are known for their durability and excellent conductivity, enhancing the module’s overall performance and longevity.
One of the notable features of this model is its lack of a defined power-up state. This means that the relays maintain their state in the event of power loss, providing a measure of reliability and predictability in your system’s behavior after unexpected power interruptions.
Despite being announced as obsolete by National Instruments, this product remains available for purchase and repairs through Apex Waves. This ensures that users can continue to rely on the high-quality performance and functionality of the SCXI-1192 model for their critical applications.
