Newport Corporation BQ90 Industrial Control Board

The Newport BQ90 Industrial Control Board is a signal-processing and control-interface module designed for precision automation and motion control systems, serving as the system-level interface that manages inputs, outputs, and communication between sensors, actuators, and higher-level controllers. It provides system-dependent analog and digital I/O, platform-dependent embedded bus communication, and low-voltage DC power, all mounted on a multi-layer PCB built with industrial-grade components for reliability in harsh environments. The board is intended for chassis or rack-mounted installations within control cabinets or embedded systems, supporting data acquisition, actuator control, and general control routing in OEM instrumentation and laboratory automation setups. Common replacements include Newport OEM replacement boards on the same motion/control platform, refurbished BQ90 assemblies from industrial surplus suppliers, or other system-dependent motion control interface boards.
