1、[2 Independent Outputs] OC OUT is NPN output, FREQ OUT is IC output. The common cathode is used with the negative GND of the power supply, and the common anode is used with the positive power supply. 2、[ABS Shell] The ABS plastic shell has good flame retardancy and insulation, which can prevent the module from overheating and spontaneous combustion, and ensure the safety of the circuit. 3、[Main Functionality] The function of this module is to control the generated frequency according to the input voltage, input 0 to 10V and output 0 to 10KHZ square wave, and the output frequency amplitude is 80 percent of the input power. 4、[Stable Performance] This module has good thermal stability, the shell is wear resistant and drop resistant, easy to install, and very stable during operation. 5、[Wide Application] This method of converting voltage into frequency is widely used in phase locking technology, analog to digital conversion, automatic 0 stabilization technology, and multiple data transmission.
