Intrinsically safe power supply to transmitter
The MCU900 Series is mounted in a non-hazardous area, and provides a protected (intrinsically safe) 24 volts direct current supply to a transmitter in a hazardous area.
Ideal for programming and control of HART transmitters
It is ideal for programming and control of Mobrey MSP Series level and flow transmitters. Other HART transmitters can be connected. The MCU900 Series recognizes the transmitters as an “unknown instruments” but allows access to programming of Universal and Common Practice HART commands.
Delta Mobrey MCU Series Features:
- Configured and interrogated using an integral six-button keypad
- Easy to navigate menu structure
- Wizard assisted programming, with password protection to prevent unauthorized access. 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
- The 4–20 mA output signal may be scaled to re-transmit all or just part of the transmitter’s input signal or calculated value
- Five relays are fully field programmable to perform a variety of control, fault indication, and alarm duties
- Two digital inputs can be individually set-up to perform various control actions (e.g. raise an alarm) whenever activated
- Provides configuration, pump or valve control and local display for any 4-20mA or HART transmitter
- Provides an ATEX approved Intrinsically Safe power supply to a transmitter in a hazardous area
- 4–20mA HART input
- Isolated 4–20mA output
