The **M2TS-1D-R/CE** is a high-performance, compact **Solid State Timer** (Time Delay Relay) manufactured by **Mitsubishi Electric** (often part of the M2TS series). This electronic component is designed for industrial automation panels where precise timing control is required. --- ### 1. Key Technical Specifications Below is a breakdown of the primary electronic characteristics of this model: | Feature | Specification | | :--- | :--- | | **Model Type** | Multi-function / Multi-range Timer | | **Input Voltage** | 100–240V AC / 100–125V DC (Universal) | | **Contact Configuration** | 1c (SPDT - Single Pole Double Throw) | | **Time Range** | Adjustable from 0.1s to 10h (multiple scales) | | **Output Type** | Relay Output | | **Mounting** | DIN Rail or Surface Mount | | **Compliance** | CE Marked (Meets European Safety Standards) | --- ### 2. Internal Electronic Structure The device consists of three main electronic stages: 1. **Power Supply Unit:** An internal switching regulator or transformer-less capacitive dropper that converts high-voltage AC/DC input into low-voltage DC to power the internal logic. 2. **Control Logic (IC/Microcontroller):** A dedicated timing IC or microcontroller that handles the clock frequency. It determines the delay based on the position of the physical potentiometers (dials) on the front face. 3. **Electromechanical Relay:** The "R" in the part number signifies a Relay output. When the timing logic reaches its threshold, it energizes an internal coil to flip the physical contacts, allowing for the switching of external loads (up to 5A typically). --- ### 3. Functional Modes The "1D" designation usually refers to its specific functional logic. Common operations for this series include: * **ON-Delay:** Timing starts when power is applied; contacts switch after the set time. * **Interval:** Contacts switch immediately upon power and revert after the set time. * **Flicker (Symmetric):** The relay continuously cycles ON and OFF at set intervals. ### 4. Terminal Configuration Example Typical wiring for this 8-pin or terminal-block style component: ```text L/+ ---- [1] (Power Input) N/- ---- [2] (Power Input) COM ---- [3] (Common Terminal) NC ---- [4] (Normally Closed) NO ---- [5] (Normally Open) ``` --- ### 5. Application Use Cases * **Motor Starters:** Delaying the transition from Star to Delta configuration. * **HVAC Systems:** Delaying fan shutdowns after a heater is turned off. * **Machine Safety:** Sequencing the activation of different components to prevent power surges.
