Product Description
The Waveshare Modbus RTU Relay (C) is an industrial relay controller module for controlling eight latching relay channels via an RS485 interface. Communication is based on the Modbus RTU protocol, allowing integration into industrial control and automation systems.
The module is intended for control cabinet and distribution installations and is supplied in a case for DIN-rail mounting. According to the manufacturer, it integrates multiple isolation and protection circuits to improve interface and control robustness in typical industrial environments.
Technical Features
- Industrial relay controller module with 8 channels
- Latching relays for state retention
- RS485 interface for serial fieldbus connectivity
- Supports Modbus RTU digital communication protocol
- Multiple isolation and protection circuits according to manufacturer
- DIN-rail mountable enclosure
- Designed for industrial switching and automation tasks
Application Areas
Typical applications include remote load switching in control cabinets, connection to PLC or industrial PC systems, and integration into building, energy, and process automation. The RS485 interface is suitable for distributed bus-based wiring topologies. The latching relays are appropriate where the switching state should remain stored after a control pulse.
