The **M5TS-24-R/Q** is a high-performance, compact industrial temperature controller manufactured by **Autonics**. It is specifically designed to provide high-speed sampling and precision PID control for industrial automation environments. --- ## 1. Core Technical Specifications The electronics of the M5TS series are built around a digital microprocessor core that handles sensor linearization and control algorithms. | Parameter | Specification Details | | :--- | :--- | | **Input Type** | Multi-input (Thermocouple: K, J, E, T, R, S, B, N / RTD: Pt100, Cu50) | | **Power Supply** | 24VDC | | **Control Output** | Relay (R) or SSR Drive (Q) - Model dependent | | **Sampling Cycle** | 50ms (High-speed processing) | | **Display Method** | 4-digit 7-segment LED | | **Mounting Type** | DIN Rail Mounting | --- ## 2. Key Electronic Components & Features ### A. High-Speed Sampling Circuit Unlike standard controllers that sample at 100ms or 500ms, the M5TS uses a **50ms sampling cycle**. This allows the electronic circuit to react almost instantly to rapid temperature changes, making it ideal for processes like plastic extrusion or high-speed packaging. ### B. Control Logic (PID & On/Off) The internal logic supports: * **PID Control:** Uses a derivative and integral algorithm to prevent overshoot. * **Auto-tuning:** The controller electronically calculates the thermal mass of the system to set its own P, I, and D constants. ### C. Communication & Integration The "M5TS" series often features integrated **RS485 communication (Modbus RTU)**. This allows the device to be part of a larger networked system (PLC or SCADA), enabling remote monitoring and parameter configuration via software like *DAQMaster*. ### D. Input/Output Isolation To protect the internal microprocessor from industrial electrical noise, the unit utilizes **opto-isolation** between the input sensor terminals, the power supply, and the output relays. --- ## 3. Terminal Configuration The device uses a slim 12.5mm design. The electronic wiring is generally grouped as follows: 1. **Power Terminals:** 24VDC Input. 2. **Sensor Input:** Terminals for connecting the Thermocouple or RTD. 3. **Control Output:** * **-R models:** Uses an internal mechanical relay. * **-Q models:** Uses a Voltage Pulse (12VDC) to trigger an external Solid State Relay (SSR). ---
