PXIe-2569

The PXIe-2569 is a PXI Relay Module from National Instruments, designed for general-purpose switching, automated test signal routing, medium-power load control, and PXI Express test systems. As a 100-channel, 1 A SPST PXI relay module, the NI PXIe-2569 provides independent single-pole single-throw Form A armature relays in a compact PXIe format. It is fully software programmable and includes a 32,000-step scan list for deterministic scanning capability, making it suitable for automated test systems that require high relay density and repeatable switching sequences.

The NI PXIe-2569 is useful for engineers who need to control a large number of independent signal paths through software. Each relay channel can be opened or closed individually, allowing users to route signals, connect test points, isolate circuits, or control medium-power test loads. Compared with lower-channel relay modules, the PXIe-2569 offers higher relay density, making it suitable for applications where many switching channels are required in a limited PXI chassis space.

One of the main advantages of the PXIe-2569 Relay Module is its 100 independent SPST Form A relay channels. This configuration provides flexible switching for automated test systems, especially when users need simple on/off control for many signal paths. The module is ideal for medium-power automated test loads and can be used in production test, functional validation, laboratory automation, and multi-point signal routing applications.

The National Instruments PXIe-2569 supports deterministic scanning through its built-in 32,000-step scan list. This allows engineers to define switching sequences in advance and execute them reliably during automated test procedures. Deterministic scan capability is especially useful for systems that require repeatable relay operations, fast test sequencing, and coordinated switching with other PXI instruments.

In system integration, the PXIe-2569 installs into a compatible PXI Express chassis and can be used alongside DAQ modules, DMMs, source measure units, signal generators, digital I/O modules, and other PXI instruments. It can be controlled through NI switch software, allowing engineers to automate relay operations from LabVIEW or other supported test software environments. This makes the module practical for building scalable PXI-based switching systems.

The PXIe-2569 PXI Relay Module is suitable for applications such as signal routing, automated production testing, electronic functional test, sensor connection switching, device validation, data acquisition channel expansion, and medium-power load switching. Its high channel count makes it especially useful when a test system needs to connect many devices, test nodes, or signal paths under software control.

Overall, the NI PXIe-2569 PXI Relay Module is a high-density switching solution for PXI Express automated test systems. With 100 independent SPST Form A relay channels, 1 A switching capability, full software programmability, and a 32,000-step deterministic scan list, the PXIe-2569 is well suited for signal routing, medium-power load control, automated validation, laboratory test, and production test applications.
