Waveshare Industrial 4-Ch PWM Output Module Modbus RTU RS485, Adjustable Frequency & Duty Cycle, Modbus RTU PWM Output 4CH

1. This product is an industrial standard isolated RS485 to PWM pulse output module. Four channels of frequency and duty cycle are independently adjustable. It adopts Modbus RTU protocol and includes built-in protection circuits such as power isolation, magnetic coupling isolation, self-recovery fuse, and TVS.2. The output uses high-speed optocoupler isolation, and the output high-level voltage can be selected via internal jumpers.3. Four channels of PWM pulse output with frequency and duty cycle independently adjustable.4. Supports setting device address (1 to 255) to cascade multiple devices via the RS485 bus.5. On-board voltage regulator chip supports wide voltage supply from 7V to 36V.6. On-board integrated power isolation provides stable isolation voltage; the isolated end requires no additional power supply.7. On-board integrated magnetic coupling isolation enables signal isolation, with high reliability and strong anti-interference capability.8. On-board self-recovery fuse and TVS (Transient Voltage Suppressor) effectively suppress surge voltage and transient spike voltage in the circuit, protecting against overcurrent, overvoltage, lightning, and static electricity.9. Built-in watchdog ensures stable output without crashing.10. Rail-mounted enclosure design, compact size, easy installation.11. External 3 LED indicators for convenient viewing of power status and signal transmission/reception status. Parameters:1. Communication Interface: RS485 2.
