Specifications:
Supply voltage:DC 6.5-25V.
Working current: 10-12MA (without any load)
Size: 35X 28X 5MM
Weight: 5 grams
Description:
MODBUS RTU Command support function code, 05/06/15/16 Write, 01/03 Read
By modifying the 485 address, up to 247 modules can be cascaded for use (please use R485 repeater for more than 16 modules)
Baud rate: 1200 2400 4800 9600 (default) 19200 38400 57600 115200BPS; Parity bit: None, Even Parity, Odd Parity
8 Darlington Transistor output (ULN2803 NPN output), the driving voltage is equal to the supply voltage. The maximum driving current of single channel is 200MA, and the maximum driving current of all channels is 800MA.
8 channels can be used as ordinary switch output, support 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 them, 1-6 channels are Low-Speed PWM channels (output parameters are expressed by Period/Turn-On-Time), output Period range: 0.1-6553.5 seconds; 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, Duty-Cycle 0-100%
Package Include:
1× Module Board
Typical Application:
Directly drive inductive loads such as relays/solenoid valves/low power motors
LED Driver/Dimming
Multilayer Signal Lights /Warning Light /Alarm signal indicator
PLC Expanding Board
Notice:
The output port is a Darlington tube open-drain output, and the port level cannot be directly measured.
Short-circuit the RESET port for 5 seconds, the module will restore the factory settings.
If it is only used to control switch output (control relay solenoid valve), please refer to ''LD58A08 MODBUS RTU Commamd(IO Version)''.
If you need to control PWM devices (LED light buzzer), please refer to ''LD58A08 MODBUS RTU Commamd(Full Version)''.
