Manufacturer 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:
Trigger voltage: low level is 0-2.5V, high level default is 3.5-5V .
Power Supply voltage: DC5V/12V/24V;
Quiescent current: 18mA;
Working current:
1-Channel 110mA;
2-Channel 198mA;
3-Channel 285mA;
4-Channel 371mA;
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 +: external trigger positive power supply, if external trigger power supply RTV + and VCC jumper to unplug
3.TRV-: external trigger negative power supply, if external trigger power supply RTV- and GND between the jumper to unplug
Relay output:
1.NO1-NO4: relay normally open interface.
2.COM1-COM4: relay common interface.
3.NC1-NC4: Relay normally closed interface.

Package Included:
1x4-Channel Relay Module

Product 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, Arduino 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);
Load: AC 250V 10A / DC 30V 10A.
