PXI Module, Relay Driver

Relay Driver modules provide the power and control signals needed to operate external relays, solenoids, or actuators. They don't switch test signals themselves but drive other switching hardware.

Key specs include channel count, output voltage, and current drive capability. These determine how many external devices can be controlled and at what power level.

In PXI, relay drivers are often used for fixture actuation or high-power load control. They synchronize with measurement modules so external switching happens in step with automated tests.
