Description

Industrial module designed for generating PWM signals via RS485 interface using Modbus RTU protocol. The device provides four independent PWM output channels with adjustable frequency and duty cycle, enabling control of actuators such as DC motors, LED lighting, and power regulation systems.

                                                                                                                     Primary function

Communication is handled through the RS485 bus, allowing operation in distributed systems and integration of multiple devices within a single network. Configurable device address enables simultaneous use of multiple modules in one installation.

                                                    Interfaces and connectors                                                           Wide voltage power supply, isolated RS485 interface

The module features galvanic isolation for both power supply and signal lines, improving noise immunity and operational safety in industrial environments. Built-in protection circuits such as resettable fuse and TVS diode protect against overvoltage, overcurrent, and electrostatic discharge.

The enclosure is suitable for DIN rail or wall mounting, allowing integration in control cabinets, industrial automation systems, and installations requiring reliable operation.
