Product Data Sheet March 2019 IP2031,Rev CC Mobrey MCU900 Series4-20 mA + HART Compatible Controller ■ Intrinsically Safe power supply to transmitter ■ 4-20mA HART input ■ Isolated 4-20mA output ■ Five control relays ■ Multi-function back lit display ■ Wall or panel mount ■ Pre-programmed linearization: contents volume and open channel flow ■ Configurable by using the integral keypad

Overview of the Mobrey MCU900 Series The MCU900 Series of wall and panel mounting control units provide comprehensive control functionality for any 4–20 mA or HART compatible transmitter. A back-lit display gives clear visual indication of the measured value and status of all inputs and outputs. Accepts any 4–20 mA or HART compatible input. (HART revisions 5, 6, and 7 are supported) Five voltage-free SPDT relays for alarm and control duties Supports two voltage-free contact closure inputs 4–20 mA 12-bit isolated current output proportional to calculated value Bright local display of measured...

Easy to navigate menu structure Wizard assisted programming, with password protection to prevent unauthorized access On-line status Configured and interrogated using an integral six-button keypad Digital communication status Many popular configurations are “Wizard assisted”, enabling fast and accurate programming. Typical applications include level, contents volume, distance measurement, and open channel flow measurement  The HART digital or 4–20 mA analog signal from the transmitter may be offset, dampened, scaled, and linearized. A range of pre-programmed linearization algorithms are user-selectable...
