Features: 1. Convert 0-5V or 0-10V analog input voltage into 0-100% PWM signal. The maximum PWM signal frequency is 20KHZ within the range of 2KHZ-20KHZ. The default is 2KHZ. The default function is a 2KHZ PWM signal of 0-10V to 0-100%. The customer can adjust the potentiometer on the board to set the corresponding output frequency according to the . 2. PWM signal and voltage can be output in direct or inverse (. positive phase output or inverse phase output). There are two kinds of PWM signals. -PWM output and NPN-PWM output respectively. -PWM output can only be 5V level, NPN-PWM output can be 5V and 24V level. 3.When NPN-PWM signal is output, it supports common cathode connection and common anode connection, with two levels of 5V and 24V. When 24V is output, 24V is required for power supply When -PWM is output, the level can only be 5V. It can only be connected with common cathode, and connected to MCU, etc. 4. The output PWM signal frequency is adjustable from 2KHZ-20KHZ. There are 11 gears, corresponding to 2KHZ, 4KHZ, 6KHZ and 8KHZ respectively. The maximum frequency is 20KHZ. The default frequency is 2KHZ 5. Module input power 7-30V The current is 200MA. The recommended power supply is 15-30VDC. When outputting 24V PWM signal, the power supply needs 24VDC power supply. An external potentiometer interface is reserved. PWM output can be set by accessing potentiometer Specifications: Product name: Voltage to PWM signal module Model: V-PWM Type: motor control Dimension: 45 x 47 x 18MM (including parts) 2, Application: 1.
