NOYITO 2-Channel Relay Module Self-locking Triggering Interlocking Optocoupler Isolation High/Low Level Trigger for PLC Industrial Control Arduino (12V)

Product Description Work: self-locking / interlocking / triggering three optional. [Self-locking - SL] Press once, relay pull, press again, relay closes. Self-locking 2-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 2 such as lighting control. [Triggering - TR ] 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 - IL ] 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 . Supply voltage: DC 5V / 12V / 24V ; Quiescent current: 12mA; Working current: 1-Channel 100mA; 2-Channel 190mA; Module Size: 63.5x38.5x18.5mm (L * W * H), Weight: 40g / 0.09 lb; Design has four bolt holes: Pitch 58x33mm, aperture 3mm. Module Interface: Trigger side: 1.CH1-CH2: Corresponds to 1-2 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-NO2: relay normally open interface. 2.COM1-COM2: relay common interface. 3.NC1-NC2: Relay normally closed interface. Package Included: 1Pcs NOYITO 2-Channel Relay Module
