Features Command Support Function Coding: Our RS485 to PWM output driver module supports function coding via RTU command, 05 06 15 16 write, 01 03 read. Output Range: 1 to 6 channels are low speed PWM channels (output parameters are expressed in period or turn on time), output period range is 0.1‑6553.5 seconds, turn on time range is 0‑6553.4 seconds (not greater than cycle time). 7 to 8 channels are hig Support Cascade: PWM output driver module can cascade up to 247 modules by modifying 485 address, 8 bit transistor output, drive voltage equal to power supply voltage. Single or Full Channel Drive Current: The RS485 to PWM output driver module has a maximum drive current of 200MA for single channel and 800MA for full channel. Switching Output: The driver module can be used as a common switching output, supporting 05 or 15 function coding to write data, or using 06 or 16 function coding to operate for 0X0080 register. Feature: 1. Output Frequency: 8 channels can be used as PWM output, output frequency range 1‑20000Hz, duty cycle 0‑100percent. Suitable for direct drive relays, solenoid valves, small power motors, PLC expansion boards, etc. Specification: Item Type: RS485 to PWM Driver Module Material: PCB Supply Voltage: DC6.5-25V Operating Current: 10-12MA (No Load) Baud Rate: 1200 2400 4800 9600 (default) 19200 38400 57600 115200BPS Check Bit: None, Even Check, Odd Check Package List: 1 x Transistor Driver Module Note: 1. The output port is a tube open drain output, and the port level cannot be measured directly. 2. Short the RESET port for 5 seconds, the module restores factory settings. 3. If only used to control the switching output (control relay solenoid valve), please refer to LD58A08 RTU Command (IO version). 4. For controlling PWM devices (LED light buzzer), please refer to LD58A08 RTU Commands (Full Version). Package List 1 x Transistor Driver Module
