China Customized PXI SPST Power Switch Module Manufacturers Suppliers Factory

PXIe 4x32 Matrix Switches - Professional Signal Routing Solutions

The PXI2931L is a 16-channel SPST power switch module based on the PXI bus architecture. It integrates sixteen independent single-pole single-throw relay channels, enabling reliable switching of medium- and high-power AC or DC loads in automated test systems.

Each channel supports switching voltages up to 125 VDC or 250 VAC, with a maximum switching current of 5 A and switching power up to 150 W / 1250 VA. The module can be used in both PXI and PXIe hybrid chassis, making it suitable for flexible test system configurations.

Description

The PXI2931L is designed for applications requiring stable, repeatable power switching within PXI-based automated test environments. By combining high-density channel integration with long-life relays, the module reduces external wiring complexity and improves system reliability.

Its fast response time, compact PXI 3U single-slot form factor, and wide environmental tolerance make it ideal for long-duration and high-cycle test scenarios.
