1. General Description:

️· The M2REB is a process indicator/totalizer used to display and totalize process variables (likely flow, but could be others).
️· It has a compact design for panel mounting.
️· It's suitable for various industrial applications.

2. Key Features:

️· Totalization: Displays and accumulates process values.
️· Multiple Input Options: Supports various input signals (details unspecified in the summary, but presumably including current loops, voltage, etc.). *Check the full spec sheet for details.*
️· Panel Mounting: Designed for easy installation into control panels.
️· Compact Size: Space-saving design.
️· DIN Rail Mounting: Can be mounted on a 35mm wide DIN rail.
️· Bright Display: Facilitates visibility under different lighting conditions.
️· User-Friendly Interface: Features front panel controls for setup and calibration.
️· Fine Calibration: Includes adjustments for zero and span, allowing for precise output matching.
️· Input Resistor: Includes an input shunt resistor for current input models.

3. Input Options

️· The specifications do not list the explicit input options available but mention support for current loops and voltage. *Consult the full document.*

4. Calibration and Adjustment:

️· Zero Adjustment: Allows the user to set the output to 0% when a calculated input signal is applied.
️· Span Adjustment: Allows the user to set the output to 100% when a calculated input signal is applied.
️· Front Panel Controls: Zero, Span, and Up/Down/Left/Right buttons for calibration and parameter adjustment.
️· Factory Settings: Units are pre-calibrated with a ratio (K) of 1 and a bias (B) of 0% for proportional characteristics, and a ratio of -1 and bias of 0% for inverted characteristics.

5. External Dimensions & Mounting:

️· Compact Design: Specific dimensions are listed (in mm and inches – see image references in the "Notes" section).
️· DIN Rail Mounting: Supports DIN rail mounting with dimensions specified.
️· Mounting Hole: A mounting hole with a depth of 6mm.
️· Terminal Assignment: A diagram (see "Notes" section) shows the terminal layout for input and power connections.
️· No Extra Space: When mounting into a panel, no extra space is needed between units.

6. Important Specifications (Not Detailed):

️· Input Signal Range: (Specific ranges are *not* listed. Consult the full specification sheet).
️· Power Supply: (Details not specified).
️· Display Type: (Not specified, but assumed to be a standard LCD or LED display.)
️· Accuracy: (Specification not given.)

NOTES - CRUCIAL for Understanding:

️· Images are Vital: The document includes images/diagrams of the front panel layout, terminal assignments, and external dimensions. *These are critical to fully understand the functionality and mounting requirements.* The summary can’t fully convey what these visuals represent.
️· Full Specification Sheet Required: This is an extract and likely a summarized version. The complete M2REB specification sheet is necessary for detailed specifications and application guidelines.
️· Model Variations: The M2REB series likely includes variations with different input ranges, display options, and features. Ensure you're referencing the correct spec sheet for your specific model.
️· REM2 (Input Resistor): The "REM2" input resistor is specifically for current input models.
