The DHA8 is a hot runner temperature controller, suitable for all hot runner heaters with a load not exceeding 15A. It features an international standard structure for its design and installation, fitting any standard enclosure. Both its power wiring system and load connection method are standard. Each control card manages the temperature of one heating circuit, with easy insertion and removal of the temperature control card, allowing for interchangeability with control cards from other manufacturers.
Features and Specifications:
The temperature control card features a touch-sensitive button and a dual-line 4-digit LED display.
The operating status is displayed through textual forms, making it intuitive and easy to understand.
Simple operation, high temperature control accuracy, new users can quickly get into the working state
The temperature control card adopts an internationally standard structure, which is easy to replace and can be interchanged with products from other manufacturers.
Each temperature control card has the same function, making them interchangeable for user convenience in maintenance and spare parts storage.
Settable for K-type and J-type thermocouple sensor signals, temperature non-linear processing and integrated cold junction compensation
Zero-crossing triggering (SSr) or phase angle control (PAc) modes are available for selection.
Temperature setting and display are available in both Celsius (℃) and Fahrenheit (℉) options.
Thermocouple breakage alarm function, automatic protection for thermocouple breakage
Thermocouple reverse connection alarm function, automatic protection for thermocouple reverse connection
Thermocouple short-circuit alarm function, automatic protection for thermocouple short-circuit
Open circuit alarm function for heating coils, automatic protection for open circuit of heating coils
