12V 8 Channels Relay Module High and Low Triggering Overview
This 12V 8 Channels Relay Module High and Low Triggering Optocoupler Isolation Relay Module PLC Signal Amplifier Board enables direct control of high-current devices using microcontrollers or PLC outputs. It provides opto-isolation for signal integrity while switching loads up to AC 250V/10A or DC 30V/10A across eight independent channels.
Key Features of 12V 8 Channels Relay Module High and Low Triggering
- Dual trigger modes: supports both high-level and low-level signal activation for flexible interfacing.
- Optocoupler isolation on each channel to protect your controller from voltage spikes.
- Eight independent relays with load capacity of AC 250V/10A and DC 30V/10A.
- TTL-compatible inputs drawing only 50–60 mA per channel, ideal for Arduino, AVR, PIC, ARM, MSP430 and PLCs.
- Clear LED indicators for each channel to show relay status at a glance.
- Genuine product with fast shipping across India from Zbotic.
Applications and Use Cases
- Home automation: drive lights, fans or pumps via Arduino or Raspberry Pi.
- Industrial control: switch motors, solenoid valves or conveyor belts in PLC systems.
- Agricultural projects: automate irrigation valves and greenhouse ventilation.
- Robotics: control high-current actuators and grippers safely.
- Security systems: manage door locks, alarms and sirens with isolated triggers.
How to Use 12V 8 Channels Relay Module High and Low Triggering
Begin by applying a stable 12V DC supply to the module’s VCC and GND pins, ensuring the common ground ties to your controller. Connect your microcontroller’s digital outputs to the desired IN1–IN8 inputs. Select high-level or low-level trigger per channel by wiring the JD-VCC jumper accordingly. Attach external loads between COM and NO/NC terminals, then drive the inputs to switch the relays on or off.

Frequently Asked Questions
Can I drive the module directly from an Arduino?
Yes. The inputs are TTL-compatible and draw 50–60 mA per channel. Use a digital pin, set it HIGH or LOW based on your trigger mode, and the optocoupler will isolate the Arduino from the relay coil.
How do I choose between high and low-level triggering?
Use the onboard jumper (JD-VCC) to select trigger mode. With the jumper set for high-level, driving an input to 12V activates the relay. For low-level, pulling the input to GND triggers the relay.
What wiring is required for a 10A AC load?
Connect your AC load’s live wire to the COM terminal and the load’s output to NO (normally open). Ensure the module’s AC side and DC side grounds are separated if isolation is required, and route wiring to handle up to 10A safely.
