Modbus PWM module RS485 bus 6-channel PWM high-power speed-regulating PWM valve

Product Description

PNP is high level output

NPN is low level output

The frequency can be changed, support 1-100KHZ, save when power off. The upgraded version is 6-channel PWM, and the PWM output signal is consistent with the input voltage. For example, if 16V pwm is required, the input terminal can be connected to a 16V voltage power supply, supporting 5-24V input

The PWM controller has 6-channel PWM signal output, which has the characteristics of wide application range, complete functions, good stability, and high performance-price ratio. It can be widely used in industrial process control systems and laboratory control systems. The communication adopts RS485 interface, which has high stability, can be controlled remotely, and can be connected to the Internet. The software adopts the MODBUS-RTU protocol, the data transmission is stable, and the universal type is good. Use pluggable terminal blocks, easy to use and firm and reliable.

Use high-power MOS tube with a maximum current of 10A, which can drive LEDs

Protocol factory default parameters:

Communication interface: RS485.

Communication format: 1 start bit, 8 data bits, no parity, 1 stop bit.

Baud rate: 9600 (can be changed by software).

Address: 1 (can be changed by software).

Communication method: The monitoring host and the device adopt a one-to-one (or one-to-many) master-slave query method.

Data protocol: MODBUS-RTU

Note: Unless otherwise specified, the data in all the commands below are in hexadecimal, and the slave address is the default 01.

The PWM signal is a low-level output (that is, PWM between the output and VCC), the output range is 0-100, corresponding to the 0-MAX voltage, that is, 0-100% duty cycle, the voltage MAX is the maximum input voltage, for example : The input voltage is 12v, the PWM signal is 12V, if the input voltage is 24V, the PWM signal is 24V.

Write duty cycle:

Tx: 01 06 00 01 00 32 59 DF Change the duty cycle of the first channel to 50%

Rx: 01 06 00 01 00 32 59 DF changed successfully

Change frequency:

The first step: Tx: 01 06 00 0F 00 32 38 1C change the frequency to 50KHZ

Rx: 01 06 00 0F 00 32 38 1C

Step 2: Tx: 01 06 00 0E 00 01 29 C9 Save the frequency setting

Rx: 01 06 00 0E 00 01 29 C9
