1、Intelligent Controller: This temperature controller is a microcomputer microcontroller controlled intelligent temperature control instrument with PID self tuning function. 2、Digital Display: This temperature controller is backlit display, both day and night can better observe the data in the screen. 3、2 Working Methods: This thermostat has heating and cooling modes, and users can choose the mode according to their needs. 4、5 Display Functions: This temperature controller has five status display, which are process value, set value, output, alarm and self tuning. 5、Auto Return: The temperature controller has a display auto return function, when forget to return to the main display mode, the meter will automatically return after 30 seconds. Item Type: PID Temperature Controller Kit Material: ABS Supply Voltage: AC100-240V 50/60HZ Input: Support 4 kinds of thermocouple (K, J, E, N) user can freely switch settings Display: Process value (PV), set value (SV), output (OUT), alarm (ALM), self tuning (AT) status display Display Temperature Unit: Celsius ℃ / Fahrenheit ℉, can switch to set the display unit Control Mode: 1.PID control (including NO/OFF, bit type PID and continuous PID) 2. Self tuning control Working Mode: Reverse action (heating), positive action (cooling), user can set Accuracy: Measurement accuracy: ±0.5%FS Sampling Period: 0.5 seconds Set Value Range: Set Value (SV): Same range (PV) Proportional Band (P): 0-full range (set 0, for NO/OFF control) Integration Time (I): 0-999 seconds (set 0 when no integration effect) Differential Time (D): 0-999 seconds (set 0 when no differential effect) Proportional Period: 1-100 seconds Bit Control Output Hysteresis Loop Width: 1-100℃ (or other PV units) Control Output: A set of main control output, while supporting the following 2 output methods for the user to choose. Relay Output: contact capacity AC250V 3A (resistive load) Voltage Pulse Output: 0-12V (for external solid state relay SSR) Alarm Function Output: One set of output, 6 modes selection Alarm output contact capacity AC250V 3A Other Parameters: Power Consumption: <10VA Use Environment: Temperature not exceeding 0-50℃, humidity not exceeding 30-80%RH without corrosive gas 1 x PID Temperature Controller 2 x Installation Holder 1 x Instruction
