5V Modbus RTU, 1Channel Relay Module, Input Optocoupler, Overview
The 5V Modbus RTU 1-Channel Relay Module with Input Optocoupler and Isolation RS485 MCU is a compact interface board designed for digital signal detection and relay-driven power control. Using a stable 8-bit MCU and standard Modbus RTU protocol over RS485, it enables reliable one-way input monitoring and one-way relay switching in industrial, smart-home, or Arduino-based projects.
Key Features of 5V Modbus RTU, 1Channel Relay Module, Input Optocoupler,
- Standard RS485 interface with Modbus RTU protocol for long-distance, noise-resistant communication
- Optocoupler isolation safeguards the MCU from voltage spikes and ground loops
- One channel relay output rated for up to 1A switching current at 5V DC
- Built-in 8-bit MCU for on-board command parsing and fast response
- Operating temperature from –25℃ to 85℃ and 5%–95% RH for harsh environments
- Compatible with Arduino, PIC, STM32 and other 5V MCU platforms
- Fast shipping from Zbotic across India
Applications and Use Cases
- Industrial automation: remote control of actuators and machinery via PLC or SCADA systems
- Smart home: switching lights, fans or security alarms over Modbus networks
- Arduino projects: reliable relay control in robotics or sensor-based triggers
- Energy management: digital signal monitoring and timed power cycling
- Data acquisition: isolated input capture combined with relay outputs
- Environmental systems: automated pump or valve control with noise immunity
How to Use 5V Modbus RTU, 1Channel Relay Module, Input Optocoupler,
Power the module with a stable 5V DC supply and connect the A/B lines of the RS485 bus to your master device (Arduino with an RS485 adapter or PLC). Tie module GND to the master’s ground. Use your controller’s serial port to send Modbus RTU commands (unit ID, function code 05) to toggle the relay. The optocoupler-isolated input can also read a digital signal, which you can query via Modbus registers for status monitoring.

Frequently Asked Questions
Q: Which protocol and communication interface does this relay module use?
A: The module uses the RS485 physical layer and standard Modbus RTU protocol, allowing multi-drop networking and reliable data exchange over long distances.
Q: What is the maximum load this relay can switch?
A: The onboard relay is rated for up to 1A at 5V DC. For higher voltage or current loads, use an external relay or contactor accordingly.
Q: Can I integrate this module with an Arduino board directly?
A: Yes. Connect the module’s RS485 A/B lines through a TTL-to-RS485 adapter to the Arduino’s serial port. After wiring 5V and GND, send Modbus RTU commands to control the relay.
