Abstract

This utility model relates to a valve opening control device, including a power supply module, a digital input module, an analog input module, an output control module, a digital output module, an analog output module, and a control module. The input terminals of the digital input modules are used to receive external digital signals; the input terminals of the analog input modules are used to receive external analog signals; the output control module outputs relay control signals; the digital output modules output internal digital signals; and the analog output modules output internal analog signals. This utility model can input digital signals to the control module through the digital input modules and analog signals to the control module through the analog input modules. The control module outputs relay control signals based on the digital or analog signals to control the position of the valve core.
