24V 8 Channels Relay, Module High and Low, Triggering Overview

This 24V 8-Channel Relay Module is an optocoupler-isolated interface board designed for high-current switching. It provides both high and low level triggering and supports Modbus serial communication, making it ideal for PLC signal amplification and microcontroller-based automation.

Key Features of 24V 8 Channels Relay, Module High and Low, Triggering

  • Eight independent relays rated AC250V 10A and DC30V 10A for robust load control
  • Optocoupler isolation on each channel to protect MCU/PLC from voltage spikes
  • High-level and low-level trigger inputs, compatible with Arduino, PIC, ARM, MSP430 and TTL logic
  • Modbus serial communication with AT command support for easy integration
  • Low driver current per channel (50–60 mA) and wide operating temperature (-25℃–85℃)
  • Fast shipping from Zbotic – get genuine modules delivered swiftly across India

Applications and Use Cases

  • PLC-based machine control in industrial automation lines
  • Smart home systems for lighting, HVAC and security device control
  • Remote switching of motors, solenoids and pumps
  • Signal amplification between low-power controllers and high-current loads
  • Integration in SCADA/Modbus networks for centralized monitoring

How to Use 24V 8 Channels Relay, Module High and Low, Triggering

Begin by supplying 24V DC to the module’s VCC and GND terminals, then wire your load to the corresponding relay COM/NO/NC contacts. Connect your microcontroller or PLC TX/RX lines to the module’s serial pins, configure the desired baud rate, and send Modbus AT commands or TTL trigger signals to switch relays on or off. Ensure common ground and verify trigger levels before operation.

Frequently Asked Questions

What communication interface does this relay module use?

This module uses Modbus serial communication with built-in AT command support, allowing you to control relays via standard RS-485/TTL lines from any compatible PLC or microcontroller.

Can the relays handle inductive loads like motors or solenoids?

Yes. Each relay is rated for AC250V 10A and DC30V 10A, making them suitable for switching inductive loads such as small motors, solenoids and pumps when proper flyback diodes or snubber circuits are used.

How much current does each channel draw when activated?

Each channel’s optocoupler input draws approximately 50–60 mA from the 24V supply when the relay coil is energized, ensuring reliable activation with minimal power overhead.
