This is the 24V variant of the 24V 4-Channel Relay Module (with Light Coupling) in Relay Modules. Available at ₹187.62 (₹159.00 + GST) with free shipping across India.
24V 4-Channel Relay Module
This 4-Channel Relay Module (with optical coupling) operates at 24V and complies with safety standards, featuring an isolation groove between the control area and the load area. The optical coupling ensures reliable and stable triggering of the relays.
The module employs a double FR-4 circuit board design and high-end SMT processing. It includes indicators for power and relay operation, while the relay terminals (C, NC, NO) are accessible via screw terminals for easy wiring.
The inputs of the 4-Channel 24V Relay Module are isolated to protect sensitive control circuitry. It is compatible with a wide range of microcontrollers, including Arduino, AVR, PIC, and ARM.
By utilizing high-voltage relays, this module minimizes the risk of overheating, as electromechanical relays regulate current consumption according to their voltage rating.
Module interface:
The positive (according to the relay voltage
VCC: connect power supply)
GND: connect power negative
IN1: relay module (effective) high-level trigger signal trigger end
IN2: relay module (effective) high-level trigger signal trigger end
IN3: relay module (effective) high-level trigger signal trigger end
IN4: relay module (effective) high-level trigger signal trigger end
Meaning of High level and Low-level
- High-level trigger refers to using the anode voltage at the VCC connection way of a trigger and triggers the end when the trigger side has a positive voltage or to trigger voltage when the relay is off.
- Low-level trigger refers to using the negative voltage at the GND connection way of a trigger and triggers the end when the trigger side has 0 v low voltage or voltage to can trigger, the relay is off.
