This is the 5V variant of the 5V 8 Channels Relay Module High and Low, Triggering Optocoupler, Isolation Relay Module, PLC Signal Amplifier, Board in Relay Modules. Available at ₹1,508.04 (₹1,278.00 + GST) with free shipping across India.
PRODUCT DESCRIPTION
This module is an 8-channel 5V relay control board featuring optocoupler isolation. It complies with international safety standards and includes isolation trenches between the control and load sections, ensuring reliable performance from high-quality relays.
The inputs of the 8-Channel 5V Relay Module are isolated to protect sensitive control circuitry. It includes indicators for power supply and relay status: when the input signal is active, the common terminal connects to the signal terminal. This module can handle both DC and AC loads up to 220V AC.
Compatible with various microcontrollers such as Arduino, AVR, PIC, and ARM, the module also features a guide rail on the backside for easy mounting in a suitable location.
Note: On the high level and low level-triggered mode, friends who do not understand, have a look
High-level trigger refers to the signal voltage between input and trigger, can be understood as a signal input with VCC cathode short-circuit triggered away;
Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, can be understood as a signal input terminal and the GND negative electrode short circuit triggered is a way 8-channel relay module connection.

How to Use 5V 8 Channels Relay Module High and Low, Triggering
Begin by supplying 5V and GND to the VCC and GND pins, then set each channel’s trigger mode (high-level or low-level) via the onboard jumper block. Connect your microcontroller digital outputs to the eight IN pins, and wire your load devices between the COM, NO, or NC terminals. Power on the module, send a logic HIGH or LOW as configured, and observe the corresponding LED lighting as each relay switches your AC or DC load.

Frequently Asked Questions
Can this module switch both AC and DC loads?
Yes. Each relay channel can handle up to 250VAC at 30A or 30VDC at 30A, making it suitable for both mains AC applications and high-current DC circuits.
How do I select high-level or low-level triggering?
Use the onboard jumper header labeled “JD-VCC” to configure trigger mode. Place the jumper to enable high-level trigger (active at 5V) or remove it for low-level trigger (active at 0V).
How do I mount this relay module securely?
The module features a guide-rail clip on the backside, allowing easy DIN-rail or panel mounting in your control cabinet without additional brackets.
The 5V 8 Channels Relay Module High and Low, Triggering Optocoupler, Isolation Relay Module, PLC Signal Amplifier, Board is a versatile relay modules used across a wide range of applications including home automation, industrial control, IoT projects, Arduino/Raspberry Pi interfacing, and motor control.
