PXI Relay Switch Modules
General Purpose PXI Relay switch modules are a powerful tool for the automation of a wide range of tasks. These modules have a variety of functions, and are easily configured to meet the needs of your applications. The National Instruments PXI-2565 provides high-current switching of AC line power, DC power sources, and DC/DC current sources. Its 16 independent Form A nonlatching relays can switch up to seven amps at 30 VDC. The intelligent front board allows you to configure the switch’s topology and association, and screen and troubleshoot the switch.
The PXI-2521 General Purpose switch relay Modules are compatible with a wide range of systems, from simple test equipment to complete industrial automation systems. These switch modules contain independent DPST armature relays with low on-resistance and thermal offsets. They are also fully software programmable, and offer support for relay count tracking. They are ideal for controlling heaters and automated test equipment.
General Purpose PXI Relay Modules can control up to 64 external relays and are designed for single and multi-channel applications. These modules support a wide range of relay types, including electromechanical armature relays, reed relays, and field-effect transistor (FET) relays. They also support NI-SWITCH driver software. The software provides a variety of help documentation and example programs, and also features a soft front-panel application for interactive control.

The major difference between a switch and a relay is their contact type. A switch has a single set of contacts, which can only conduct current through one circuit, while a relay has two sets of contacts, which can control two different circuits simultaneously. In some cases, the two types of switches are used interchangeably.
Contactors and switches are used when there is a high electrical load. They usually have safety features to prevent a short circuit or overload. Relays, on the other hand, are used when a circuit needs to switch to low power. They also have spring-loaded contacts, which ensure that the contacts are held open even when the switch is de-energized.
Relays are passive devices that control electrical current in a circuit. They are not normally used to control power-consuming devices, but they can be used to “control” larger voltages and amperes. Relays are also used to protect equipment against electrical abnormalities such as overcurrents, overloads, and reverse currents. These devices are typically used in industrial settings, but their versatility also extends to home applications.
The difference between a switch and a relay can be quite substantial. Relays are typically much bigger than switches, but they operate on lower currents and can also be controlled by a smaller switch. Generally, a relay can handle 20 amps or less, while a switch can handle nine amps or more.
