Description
Product Introduction
The Mobrey MCU901WX-A/RS Universal Control Unit is an industrial process controller from the MCU900 series, designed for use with compatible 4–20 mA and HART-enabled transmitters. It is suitable for applications involving liquid-level monitoring, tank-content measurement, pump control, and open-channel flow measurement.
The controller receives measurement signals, processes the configured values, and provides relay control outputs and an isolated 4–20 mA output for integration with other equipment. Its wall-mounted enclosure is designed for demanding industrial environments, while the integrated display and keypad support local monitoring and configuration.
The MCU901WX-A model is specified as a wall-mounted, ATEX-certified version. Confirm the complete MCU901WX-A/RS designation and electrical configuration against the equipment nameplate before installation.
