The DHT2 is a hot runner temperature controller, suitable for all hot runner heaters with a load not exceeding 15A. Its power wiring and load connection are both in a standard configuration. Each control card can independently control the temperature of two heating circuits, and the temperature control card is easy to insert and remove.

Features and Specifications:

The temperature control card operates with a touch-sensitive button and a dual-line 4-digit LED display.

Operating status is displayed through textual representation, offering a直观 and easily understandable visual.

Simple operation, high temperature control accuracy, new users can quickly get into the working state.

Each hot runner temperature control card has the same function, so they are interchangeable for user convenience in maintenance and spare parts storage.

 Settable K-type and J-type thermocouple sensor signals, temperature non-linear processing and integrated cold junction compensation

Zero-crossing trigger mode (SSr) or phase angle control mode (PAc) is available for selection.

Temperature settings and display are available in both Celsius (°C) and Fahrenheit (°F).

Thermocouple open-circuit alarm function, automatic protection for thermocouple open-circuit

Thermocouple reverse connection alarm function, automatic protection for thermocouple reverse connection

Thermocouple short-circuit alarm function, automatic protection for thermocouple short-circuit

Heating element open circuit alarm function, automatic protection for heating element open circuit

Silicon controlled rectifier breakdown alarm function

FUZYY+PID control algorithm, with PID parameters featuring both online automatic tuning and manual setting options

Equipped with hot runner soft start heating method, the soft start heating power and heating time can be freely set.

The system is equipped with both automatic and manual control methods, the latter for heating in special circumstances.

featuring 380V voltage misconnection protection to ensure the safety of the temperature control box.
