Description
The 779313-01 is a specialized component in the category of PXI Digital I/O, specifically model PXI-6521. This unit is designed as an 8 In/8 Out Relay Board, capable of handling voltages up to ±30 VDC. It features 16 channels, which includes 8 relay outputs and 8 sink/source inputs, providing flexibility for various applications.
This board is characterized by its high channel isolation, ensuring robust performance and reliability in demanding environments. It operates with industry-standard logic levels of 24 V and includes a keyed connector for secure and easy connection.
It adheres to Measurement Category II, with a signal voltage capacity of ≤ 150 V and can withstand surge voltages of up to 1,500 V. The relay states are designed to switch from COM to NO when energized and from COM to NC when de-energized. Additionally, the power-up state is user-configurable with NI-DAQ/LabVIEW, offering customization to meet specific user requirements.
The PXI-6521 also supports monitoring changes on all or selected input lines and allows for programmable interrupts against input line changes. This feature enhances its capability to respond to environmental changes swiftly.
With a maximum switching power of 60 W/60 VA and an operating power requirement of 100 mA max at 3.3 V (±5%), 300 mA at 5 V, this relay board is both powerful and efficient. Its ability to handle a maximum voltage of 150 VAC makes it suitable for a wide range of applications in various industrial settings.
