NOYITO 4-Channel Relay Module DC 5V 12V 24V Features

• This module is widely used in the design and development of the home and industrial electronic products of the majority of electronic enthusiasts, can be a good signal input source for the microcontroller, especially for the design of electronic circuits for students in institutions of higher learning. For automation equipment modification, PLC industrial control, robot, smart products.

• Double-board design with PCB, 4-channel independent design, do not interfere with each other. The use of single-chip design, stable and reliable performance, strong anti-interference, not false trigger, superior performance.

• Trigger optocoupler isolation, the trigger power supply can be an independent external power supply, truly complete isolation. (If you need external trigger power: DC12V version of the trigger, in series with a 5.1-6.8K resistance; DC24V version of the trigger, in series with a 15-22K resistance; Otherwise it will damage the chip)

• With 4 tactile switches as a product test to directly verify product stability(Low-level trigger valid); with power indicator (green LED) and 4 switch indicators (red LED)

About NOYITO 4-Channel Relay Module DC 5V 12V 24V

Description Product Description Work: self-locking / interlocking / triggering three optional. [Self-locking] Press once, relay pull, press again, relay closes. Self-locking 4-Channel independent of each other without affecting each other, but also can be an external trigger switch (CH terminal wiring), with high or low triggering (optional), can control 4 such as lighting control. [Triggering ] Press the relay pull, release the button relay off. It is also possible to connect the trigger switch (CH terminal wiring) and trigger with high level or low level (optional). [Interlocking] Typical application of fan design, when S1 is pressed, S1 relay pull; when S2 is pressed, S1 is off, S2 relay pull. 2-channel interlock can only be connected all the way, but also an external trigger switch (CH terminal wiring), with high or low trigger (optional). Electrical parameters: Quiescent current: 22mA; Working current: 1-Channel 45mA; 2-Channel 68mA; 3-Channel 91mA; 4-Channel 111mA; Module Size: 77x57.5x18.5mm (L * W * H), Weight: 70g / 0.16 lb; Design has four bolt holes: Pitch 71x51mm, aperture 3mm. Module Interface: Trigger side: 1.CH1-CH4: Corresponds to 1-4 relay trigger control terminal, supports high or low level trigger trigger; 2.TRV +: Connected to external trigger positive (if use external trigger , RTV + and VCC jumper cap need to unplug) 3.TRV-: Connected to external trigger negative (if use external trigger, RTV- and GND jumper cap need to unplug) If the external trigger is not used, the TRV+, TRV-two jumper caps need to be plugged in. If the external trigger is used, the TRV+, TRV-two jumper caps do not need to be plugged in. Relay output: 1.NO1-NO4: NO 2.COM1-COM4: COM 3.NC1-NC4: NC.
