The YYNMOS-1
Supplier description
- Model: YYNMOS-1
- Input and output are completely isolated
- Input Signal: 3-20V PWM signal
- Output Capacity: DC 3.7-27V, and the current is within 10A
- PWM Frequency: 0-20KHz
Application
The output port can control high power devices, such as motors, lamps, LED lamp strings, DC motors, micro water pumps, electromagnet valves; it can input PWM to control motor rotate speed and the brightness of a lamp.
The YYNMOS-1 module is described here and has one channel. There exists also a YYNMOS-4 module, which is a four-channel version.
The YYNMOS-4
Interface Introduction
| Pin | Specification |
|---|---|
| DC+ | The positive pole of the device's DC power supply |
| DC- | The negative pole of the device's DC power supply |
| PWM | Signal input positive terminal (connects to MCU IO ports, PLC interface) |
| GND | signal input negative terminal |
| OUT+ | Positive output terminal (connects to the positive pole of the device) |
| OUT- | Negative output terminal (connects to the negative pole of the device) |
Reverse engineered schema of the module. Somebody knows the type numbers of the diodes?
About R1: the module in the picture has a value of 470Ω, the one I bought has 2K2.
About R3: the module in the picture has a value of 100K, the one I bought has 10K.
