The **M2AMS2-C1-R2/CE** is a high-precision, industrial-grade **Signal Conditioner** (also known as a transducer or isolator) manufactured by **M-System**. It is specifically designed to convert an AC current input into a standard DC output signal. --- ### 1. Key Technical Specifications The model name encodes specific electronic characteristics. Below is a breakdown of the hardware specifications: | Component | Specification | Description | | :--- | :--- | :--- | | **Input Signal** | AC Current (0 – 1A AC) | Designed for power monitoring systems. | | **Output Signal** | 4 – 20 mA DC | Standard industrial current loop output. | | **Power Input** | 24V DC | Internal electronics operate on low voltage DC. | | **Isolation** | 3-Way Isolation | Input, Output, and Power are galvanically isolated. | | **Mounting** | DIN Rail | Standard 35mm industrial rail mounting. | --- ### 2. Core Electronic Functions #### A. Signal Conversion (AC to DC) The internal circuitry utilizes a precision rectifier and filtering stage. It takes a non-linear or sinusoidal AC input (usually from a Current Transformer) and converts it into a highly linear, proportional DC signal. #### B. Galvanic Isolation This is a critical electronic feature. It uses **magnetic or optical coupling** to ensure that high-voltage surges or noise on the input side (AC line) do not damage the sensitive PLC or controller on the output side. * **Dielectric Strength:** Usually rated for 2000V AC for 1 minute. #### C. Response and Accuracy The electronics are tuned for high-speed industrial feedback: * **Response Time:** Approximately 0.5 seconds (to 90% of signal). * **Accuracy:** Typically ±0.3% of span, ensuring minimal data loss during conversion. --- ### 3. Connection Diagram (General) The unit typically uses a base-socket design for easy maintenance. ```text [ AC INPUT ] ---> [ RECTIFIER/ISOLATOR ] ---> [ DC OUTPUT ] (1A AC) (Internal Logic) (4-20mA) ^ ^ | |_____________________|______________________| [ 24V DC POWER ] ``` --- ### 4. Certifications * **CE Marking:** Indicates compliance with European safety, health, and environmental protection requirements (EMC Directive and Low Voltage Directive). * **R2 Series:** Part of M-System's compact "M2" series, optimized for space-saving in control panels.
