National Instruments PXI-2521 PXI Relay Module

The NI PXI-2521 PXI Relay Module (Part Number: 778572-21) has over-temperature conditions that are made when exorbitant power dissipates in channel routes, such as while changing expansive impulses created by switching in capacitive or inductive loads or when a signal is changed at a quicker rate than the module dissipates the heat produced. The PXI-2521 Switch Module offers 40 independent DPST relays, 2 A switching / A carry, 150 V of maximum voltage and it is fully software programmable.

The NI Switch Health Center is incorporated in the PXI-2521; this is a free application that installs with the NI-SWITCH driver that can be utilized to screen individual relay health, guide relay replacement, and produce client reports. The NI Switch Health Center checks the state of each bus by sending a signal through a mix of routes and cautioning clients if a relay has failed stuck open or shut. Furthermore, huge changes in contact resistance after some time can demonstrate that a relay is approaching or has achieved end of life. The NI Switch Health Center tests for changes in resistance utilizing the incorporated relay resistance test, enabling the user to see the resistance change crosswise over individual relays and decide if the relay is nearing the finish of its usable life. A substantial change in resistance from the baseline shows that the user will soon need to supplant the relay.
