1. 0-5V or 0-10V analog input voltage into 0-100% PWM signal. PWM signal frequency 2KHZ-20KHZ range, the maximum is 20KHZ. Default is the minimum is 2KHZ. default function is 0-10V to 0-100% of the 2KHZ PWM signal, customers can adjust the potentiometer on the board to set the corresponding frequency output size according to demand.2. PWM signal and voltage can be proportional or inversely proportional to the output. (. positive phase output or inverse phase output) 2 1.3. There are two types of PWM signals. They are -PWM output and NPN-PWM output. Among , -PWM output can only be 5V level, NPN-PWM output has two kinds of 5V and 24V level. When NPN-PWM signal is output, it supports common negative connection and common positive connection, and there are two kinds of levels: 5V and 24V. When outputting 24V level, the power supply must be 24V.4. When -PWM output, the level can only be 5V. Only common negative wiring can be connected to MCU, etc. The output PWM signal frequency is adjustable from 2KHZ to 20KHZ, with 11 steps, corresponding to 2KHZ, 4KHZ, 6KHZ, 8KHZ and 20KHZ. 2KHZ is the default frequency.5. module input power supply 7-30V. 200MA current can be. Recommended power supply 15-30VDC. 24VDC power supply is required when outputting 24V level PWM signal. reserved for external potentiometer interface. You can access the potentiometer to set the PWM output, external potentiometer to adjust the need for customization.Size: 45 x 47 x 18MM (including parts)The application.1. for PWM motor speed control interface circuit.2. for instrumentation AD interface conversion.Material: PCBcolour: as shownPackage Contents:1 x signal moduleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing.
