1. What it Is: M2SBS Isolator/Converter

️· Function: This is a DIN rail mountable, isolated signal converter. It takes an input signal (current or voltage) and converts it to a standardized output signal. Isolation means it electrically separates the input and output circuits for safety and noise reduction.
️· Manufacturer: M-System
️· DIN Rail Mountable: Designed to easily snap onto a standard DIN rail, simplifying installation in industrial control panels.

2. Input Options

️· Current or Voltage: It supports both current and voltage input signals. (Internal shunt resistors are used for current inputs).
️· Configurable Ranges: Input ranges are likely configurable (not explicitly detailed in this document, but typical for this type of product).

3. Output Options

️· Standardized: The output is a standardized signal, most likely for easy integration with PLCs, DAQs, and other control systems.
️· Likely Outputs: The document doesn't definitively list output types, but the “Schematic Circuitry & Connection Diagram” suggests potential digital outputs and a "Low Drift Digital Output."

4. Key Features & Specifications

️· Isolation: Provides electrical isolation between input, output, and power circuits.
️· Low Drift: "Low Drift" refers to minimal signal error over time and temperature changes, which is crucial for accuracy.
️· Reinforced Insulation: (300V) for inputs 1 or 2 to output.
️· Basic Insulation: (300V) for input 1 or 2 to output.
️· Accuracy: High accuracy, thanks to the "Low Drift" design. (See "Accuracy" within the "Performance Characteristics" section for specific numbers).
️· Operating Temperature: Not explicitly stated, but a typical industrial range.
️· Supply Voltage: Not explicitly stated, but a typical industrial range.

5. Safety & Approvals

️· EMC Compliance: Meets European EMC Directives (EMI and EMS).
️· Low Voltage Directive: Complies with European Low Voltage Directive.
️· RoHS Compliant: Meets the RoHS directive regarding hazardous substances.
️· UL/C-UL Approval: Approved for use in Class I, Division 2 hazardous locations (North America). Meets general safety requirements.
️· Measurement Category: Measurement Category II (input) and Installation Category II (power).
️· Pollution Degree: Pollution Degree 2.

6. Physical Characteristics

️· Dimensions: 114 mm x 21.5 mm (4.49" x .85") - A compact size for DIN rail mounting.
️· Mounting: DIN rail (35mm wide). No extra space needed between units.
️· Terminal Assignments: Screw terminals, likely accepting a range of wire sizes.

7. Understanding the Diagrams & Tables:

️· Schematic Circuitry: Shows the internal blocks and connections (amplifier, computation driver, etc.).
️· Connection Diagram: Illustrates how to wire the unit to external devices. Pay close attention to polarity (+ and -).
️· Terminal Assignments: Lists the function of each terminal (e.g., +Input, -Input, +Output, -Output, Power +, Power -).
️· External Dimensions: A technical drawing showing the physical dimensions.
