The Keysight M9135A is a PXIe general-purpose SPST power relay module delivering 20 independent Form A switches for high-density switching of heavy loads and power supplies. Each channel switches up to 5 A at 250 Vrms or 125 Vrms, supporting DC resistive loads up to 300 W. The module accommodates inductive and capacitive loads and integrates into PXI chassis via J1 connectors for fast configuration and control through Keysight Connection Expert, soft front panels, and standard programming environments.
