Modbus RTU PWM Output Module 4CH, Isolated RS485 to 4-Channel PWM Controller, Adjustable Frequency & Duty Cycle, 7-36V Power Input, DIN Rail Mount Case, Surge/TVS Protection, LEDs

- ◎ Modbus RTU RS485 to PWM Output Module: Industrial Modbus RTU PWM output module converts RS485 commands to 4-channel PWM outputs, ideal for PLC/automation control and remote dimming/speed control applications.
- ▣ 4CH PWM with Independent Control: Provides 4-ch PWM outputs with independently adjustable frequency and duty cycle, enabling precise control for fans, valves, drivers, dimmers, and other PWM devices.
- ⛓ Isolated RS485 Interface + Optocoupler Outputs: Features power isolation and magnetical isolation on the RS485 interface, plus high-speed optocoupler isolation on PWM outputs for high reliability and strong anti-interference.
- ⚡ 7–36V Wide Voltage Input + No Extra Isolated Supply: Built-in regulator supports 7-36V power supply, and onboard unibody isolated power design provides stable isolated voltage—no additional power supply needed for the isolated terminal.
- 🛡 Protection, Watchdog & DIN Rail Mount: Includes resettable fuse, TVS surge protection (transient spike suppression), and watchdog for stable operation; compact DIN rail mount enclosure with 3 LEDs for power and signal status.
