The Waveshare Modbus RTU 16-Ch Relay Module, RS485 Interface, w/ Multiple Isolation Protection Circuits is an industrial-grade relay module designed for robust and reliable control applications. It operates via the RS485 bus and utilizes the Modbus RTU protocol, ensuring fast and stable communication. The module is equipped with multiple isolation protection circuits, including power supply isolation, magnetic isolation, and optocoupler isolation, which enhance its safety and reliability by preventing interference from high-voltage circuits.

Housed in a rail-mounted ABS case, this module is easy to install and provides a secure enclosure for industrial environments. It features a configurable device address, allowing multiple devices to be cascaded on the RS485 bus, which is particularly beneficial for applications requiring long communication distances. The module's onboard relay driver chip, complete with freewheeling diode protection, ensures strong and stable driving capability.

The relay module supports a contact rating of up to 10A at 250VAC or 30VDC, making it suitable for directly controlling home appliances or devices within these voltage limits. LED indicators provide clear status updates for the MCU and data transmission processes, enhancing operational transparency. The inclusion of a resettable fuse and TVS diode offers additional protection against over-current, over-voltage, and transient spikes, ensuring the module's durability and longevity.
