About 4-Channel Relay Module DC 5V 12V 24V Self-locking

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
