1 Road/Channel Relay Module (With Light Coupling) 24V

Because the load area and control regions feature isolation grooves, this single road/channel relay module (with light coupling) operates at 24 volts and complies with safety standards. isolator module for optical couplings.

One road/channel relay module triggers more steadily and dependably. The premium SMT process for double FR – 4 circuit board design. It contains instructions for relay and power operations. Screw terminals provide simple access to the C, NC, and NO relay terminals, simplifying the wiring of the board. Transistor BC547 safely drives the relay, protecting your Arduino or other input device from relay circuitry.

One channel 24 volt relay module’s inputs are segregated to safeguard any fragile control electronics.

It can be controlled by a variety of microcontrollers, including Arduino, AVR, PIC, ARM, and others.

Utilising such a relay removes the possibility of the relay overheating because electromechanical relays regulate current consumption based on voltage rating.

Module interface:

The positive (according to the relay voltage VCC: connect power supply)
GND: connect power negative
IN: relay module (effective) trigger end

Meaning of High level and Low-level

1. 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 the positive voltage or to trigger voltage when the relay is off.
2. 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.

Note: The relay module is low level trigger relay.
