The **E5CD-RX2D6M-002** is a high-performance digital temperature controller belonging to Omron’s E5CD series. It is designed for precision control in industrial automation, featuring a compact 48x48 mm (1/16 DIN) chassis. --- ### ## Technical Specifications Overview | Feature | Specification | | :--- | :--- | | **Input Power** | 24 VAC/VDC | | **Control Output 1** | Relay Output (SPST-NO, 250 VAC, 3 A) | | **Auxiliary Outputs** | 2 Independent Relay Outputs | | **Input Type** | Multi-input (Thermocouple, PT100, Infrared, or Analog) | | **Sampling Period** | 50 ms (High-speed processing) | | **Terminal Type** | Screw terminals | --- ### ### Key Electronic Components and Features #### 1. Microcontroller & PID Engine The core of the E5CD is its high-speed processor capable of a **50 ms sampling cycle**. It utilizes **2-PID control** (Two-degrees-of-freedom PID) which allows the unit to optimize both response to setpoint changes and disturbance rejection simultaneously. #### 2. Universal Sensor Input The electronics are designed to interface with a wide variety of industrial sensors without hardware modification: * **Temperature Sensors:** Thermocouples (K, J, T, E, L, U, N, R, S, B, W, or PL II) and Platinum Resistance Thermometers (Pt100, JPt100). * **Analog Inputs:** Current (4 to 20 mA, 0 to 20 mA) or Voltage (1 to 5 V, 0 to 5 V, 0 to 10 V). #### 3. Control & Auxiliary Outputs * **Relay Output (RX):** The "R" in the model name indicates a Relay output. This is a mechanical relay capable of switching loads up to 3A at 250VAC. * **Event Inputs/Outputs:** The "2" indicates two auxiliary outputs, typically used for high/low temperature alarms or system error signaling. #### 4. Display and Interface The unit features a high-contrast VA (Vertical Alignment) LCD display: * **PV (Process Value):** White (highly visible). * **SV (Set Value):** Green. * **Status Indicators:** Indicate output state, ALM (alarm), and adaptive control status. --- ### ### Advanced Electronic Functions * **Adaptive Control:** The E5CD includes algorithms that automatically calculate the optimal PID constants. It can detect changes in the controlled system and adjust itself accordingly. * **Water-Resistance:** The front panel is rated **IP66**, meaning the electronic display and buttons are protected against powerful water jets and dust. * **Safety Standards:** Built-in protection against electrical noise and surge, compliant with UL/CSA and CE marking standards. ---
