Description
The part number 776572-75 refers to a specific model of PXI Switches, specifically the SCXI-1175. This device falls under the category of Matrix/Multiplexer Switch Module, designed and manufactured by National Instruments. It is designed to handle a maximum signal voltage of 100 V and can withstand impulse voltages of up to 500 V, making it suitable for various high-voltage applications.
The SCXI-1175 module requires a control cable, and it is compatible with either the SH9MD-AUX (1 or 2 m), or the USB-13xx (standard 1 m USB link) for connectivity. For high-voltage backplane interconnects, the HV8-HV8 cable is used, whereas the HV8-BAN4 cable is necessary for DMM connection. This ensures versatile and reliable connections across different setups.
When it comes to power handling, the module can manage a maximum switching power per channel of 30W, with a DC isolation resistance greater than 1 GΩ. The maximum total current that can be managed by the module is 1A, and it boasts a fast relay operating time, typically around 1ms. Additionally, the maximum channel-to-channel voltage is capped at 100 V, ensuring safe operation within its specified limits.
Despite its advanced features, the SCXI-1175 has been announced as obsolete by National Instruments. However, it remains available for purchase and repairs through Apex Waves, offering a lifeline for systems that rely on this specific model. This ensures that users can continue to benefit from its robust performance and reliability in their applications.
