Tsophreniq 8ch RS485 MODBUS RTU DO/PWM Output Multifunction MOS Driver for Multilayer Transistors Modules Power Module

MODBUS RTU Command function code: Write 05 / 06 / 15 / 16, Read 01 / 03 8 Transistors output ( ULN2803 output), the driving voltage is equal to the supply voltage The driving current of single channel is 200MA, and the driving current of all channels is 800MA 8 channels can be used as ordinary switches output, 05 / 15 function code to write data, or use 06 / 16 function code to operate the 0X0080 register 8 channels can also be used as PWM output Among, 1-6 channels are Low-Speed PWM channels ( output parameters are expressed by Period / Turn-On-Time), Turn-On-Time range: 0-6553.4 seconds ( not greater than Cycle time) 7-8 channels are High-Speed PWM channels ( output parameters are expressed by Frequency / Duty-Cycle), output Frequency range: 1-20000Hz By modifying the 485 address, up to 247 modules can be cascaded for use ( please use R485 for more than 16 modules
