The **FCR-16Z-R** is a high-performance, programmable digital temperature controller manufactured by **Shinko Technos**. It is designed for industrial applications requiring precise PID control in a compact 48x48mm (1/16 DIN) form factor. --- ### 1. Technical Specifications Overview The following table highlights the core electronic characteristics of the FCR-16Z-R: | Feature | Specification | | :--- | :--- | | **Power Supply** | 100 to 240V AC (Standard) / 24V AC/DC (Optional) | | **Input Type** | Multi-input (Thermocouple, RTD, DC Voltage, DC Current) | | **Output Type (R)** | **Relay Contact Output** (1a, 250V AC 3A) | | **Control Method** | PID (with auto-tuning) or ON/OFF control | | **Display** | 4-digit Red LED (Process Value) and Green LED (Set Value) | | **Sampling Period** | 0.25 seconds | | **Memory** | Non-volatile (EEPROM) | --- ### 2. Key Electronic Components & Terminals The device consists of several critical electronic sub-systems: #### A. Control Output (The "-R" Suffix) The "R" in the model name indicates that the primary control output is a **Relay**. * **Function:** It acts as an electronic switch to turn heaters or cooling elements on/off. * **Capacity:** Rated for 3A resistive loads. For high-power industrial heaters, this relay typically triggers a larger External Contactor or Magnetic Switch. #### B. Universal Input Circuit The FCR series features a sophisticated input stage that can be configured via software to read different sensors: * **Thermocouples:** K, J, R, S, B, E, T, N, etc. * **RTDs:** Pt100, JPt100 (3-wire system for lead-wire resistance compensation). * **Linear Inputs:** 4-20mA or 0-10V (requires shunt resistors for current). #### C. Communication & Alarms * **Alarm Outputs:** Usually equipped with one or two alarm relay outputs (A1/A2) for over-temperature protection. * **Retransmission (Optional):** Some variants allow sending the process value as a 4-20mA signal to a PLC or chart recorder. --- ### 3. Wiring Configuration (General) The back of the unit features a terminal block usually mapped as follows: 1. **Terminals 1-2:** Power Supply (AC or DC). 2. **Terminals 3-5:** Control Output (Relay Contact). 3. **Terminals 7-9:** Input Sensor (Thermocouple or RTD). 4. **Terminals 10-12:** Event/Alarm Outputs. --- ### 4. Distinctive Features * **Auto-tuning:** Automatically calculates PID constants (Proportional, Integral, Derivative) to stabilize the temperature. * **Dust/Drip-proof:** The front panel usually carries an IP66 rating, protecting the electronics from harsh industrial environments. ---
