Provides sequential display selection, TTL-compatible external control, and rear panel adjustment for gas correction factors. ## Platform Designed for integration in laboratory and industrial gas flow control systems, the device operates within electronic instrumentation racks and interfaces primarily with MKS analog mass flow controllers and meters through 0-5 VDC analog signals. It supplies ±15 VDC power to four channels, each providing signal conditioning, set point control, and flow readout via a sequenced 3½-digit Digital Panel Meter (DPM). Communication and control are achieved through manual front panel controls, external 0-5 VDC set point inputs, and TTL-compatible ON/OFF signals. It supports gas correction scaling on the rear panel and can be integrated into larger process control systems using standard interface cables. Typical applications include multi-gas flow monitoring, set point control, and ratioed gas mixing in vacuum and semiconductor processing environments. ## Application This equipment is typically used in vacuum processing applications, semiconductor manufacturing, and laboratory research environments. It provides power and readout functions for mass flow controllers and meters, enabling precise control and monitoring of gas flow rates. Its multiple channels and compatibility with external set points make it suitable for sophisticated flow management systems requiring accurate scaling and signal output adjustments. ## Images - - - -
