Solid State Relay Output Signal: 15±8V 30mA Power Supply: 220-V-±10% 50HZ Power Consumption: 4W Operating Environment: 0-50℃, relative humidity 35%-85%RH, non erosion and non strong electromagnetic field radiation environment Size: Approx. 112 x 48 x 96mm / 4.4 x 1.9 x 3.8in Package List: 1 x Smart Temperature Controller 2 x Accessories Notice: 1. Correctly wire according to the wiring diagram. 2. For the thermocouple input signal, please use the compensation wire of the same material as the thermocouple wire. 3. For the thermal resistance input signal, use the same specifications of low resistance wire, and the length of the three wires should be the same as far as possible. 4. Pay special attention to not confusing the power input line with the sensor signal input line; otherwise, the entire instrument will be burnt out and cannot be repaired. The output terminal should not be short circuited by high currents. 5. Separate the power line and signal line from the high current output lines as much as possible to reduce electromagnetic radiation affecting the instrument.
