Command Support Function Coding: Our RS485 to PWM output driver module supports function coding via RTU command, with 05 06 0F 10 for writing and 01 03 for reading. Output Range: Channels 1-6 are low-speed PWM channels (output parameters expressed in period or duty cycle), with an output period range of 0.1-6553.5 seconds and a duty cycle range of 0-6553.4 seconds (not exceeding the cycle time). Channels 7-8 are high-speed PWM channels (output parameters expressed in frequency or duty cycle). Supports Cascading: The PWM output driver module can cascade up to 247 modules by changing the 485 address. It features an 8-bit transistor output with a drive voltage equal to the supply voltage. Single or Full Channel Drive Current: The RS485 to PWM output driver module offers a maximum drive current of 200MA for a single channel and 800MA for the full channel. Switch Output: The driver module can function as a standard switch output, supporting 05 or 0F function coding for data writing, or utilize 06 or 10 function coding to operate the 0X0080 register. Output Frequency: All 8 channels can be used as PWM output, with an output frequency range of 1-20000Hz and a duty cycle of 0-100%. Suitable for directly driving relays, solenoid valves, small power motors, PLC expansion boards, etc. 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 Parity Bit: None, Even, Odd
