The **M2TS-4D-R/CE** is a high-performance **Solid State Relay (SSR)** typically manufactured by **M-System** (now part of the MG CO., LTD). This specific model is designed for high-speed switching and interface isolation in industrial automation environments. ### 1. Key Technical Specifications Below are the primary electronic characteristics for the M2TS-4D-R/CE model: | Parameter | Specification | | :--- | :--- | | **Input Type** | DC Voltage (Control side) | | **Input Voltage Range** | 4 - 32V DC | | **Output Type** | Photo-MOSFET Relay | | **Output Rating** | 0.5A @ 100V DC / 0.5A @ 100V AC | | **Isolation** | 2000V AC (Input to Output to Ground) | | **Response Time** | Max 2 ms (Turn-on/off) | | **Dielectric Strength** | 2000V AC @ 1 minute | | **Housing Material** | Flame-resistant resin (Black) | --- ### 2. Electronic Component Breakdown The "M2TS-4D-R/CE" part number identifies specific electronic attributes: #### A. Input Section (Control Side) The device uses an internal **LED (Optocoupler input)**. When DC voltage is applied to the input terminals, the LED glows, activating the light-sensitive MOSFET driver on the output side. This ensures complete electrical isolation between the control PLC/Controller and the load. #### B. Output Section (Power Side) Unlike traditional mechanical relays, this unit uses **Photo-MOSFET technology**: * **No Arcing:** Because there are no physical contacts, there is no electrical sparking. * **High Frequency:** It can handle rapid switching cycles that would destroy a mechanical relay. * **Low Leakage:** It provides a very low "off-state" leakage current compared to Triac-based SSRs. #### C. Power Supply & Compliance * **R/CE Suffix:** The "R" usually indicates the power requirement (e.g., 24V DC auxiliary power), and "CE" indicates compliance with European safety and electromagnetic compatibility standards. --- ### 3.
