This product is a multi turn electronic control assembly developed to match the DZW series cast iron models. Low power control assembly, using circuit to directly drive asynchronous motors below 0.75KW. High power control assemblies above 1.1KW require the use of AC contactors to drive three-phase AC asynchronous motors. The non-invasive series is highly praised by customers for its excellent cost-effectiveness. The core component adopts our company's very mature multi circle absolute value encoder to collect valve position, combined with intelligent circuit board to achieve non-invasive cover free debugging and operation. Accept remote control switch signals or analog signals to control the AC asynchronous motor to perform switch or adjustment actions. Output one analog valve position feedback signal and four relay signals to indicate fully closed, fully open, remote, and comprehensive faults. MODBUS-RTU bus and 4G wireless communication can be added. The intelligent model adopts a full Chinese character menu, with complete functions such as parameter configuration, signal query, fault diagnosis and protection, data recording, etc. Output 6 configurable relay dry contacts and can be expanded with 4 additional relays. MODBUS, PROFIBUS, HART, CAN, FF and other bus communication can be added. 4G, LORA, NB-IOT and other wireless communication controlled by cloud platform can also be selected to achieve IoT control.
