LM YN 2-Channel Relay Control Module Interlock Self-Lock Trigger 3 in 1 Relay Module High Low Level Trigger with Indicators for Household Appliances Control PLC Industrial Control Arduino (5V): Home & Kitchen

Description

Features: Working methods are self-locking / interlocking / triggering three optional 1. [Self-locking] Press once, relay pull. Press again, the relay is off. Self-locking independent of each other independently of each other, but also can be an external trigger switch (CH terminal wiring), with high or low trigger (optional), can control multiple, such as lighting control. 2.[ Triggering (jog)] Is pressed when 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). Suitable for such as electric door, electric door locks, docking with the microcontroller and so only need a high or low pulse circuit. 3. [Interlocking] Press the corresponding button, corresponding to the relay suck and the other 1 way off, 2-Channel only one way will be locked, similar to the fan gear switch, you can not both work at the same time. Relay can also be an external trigger switch (CH terminal wiring), with high or low trigger (optional). Practical applications such as fan stall switch circuit. Electrical parameters: Trigger voltage: low level is 0-2.5V, high level default is 3.5-5V; Supply voltage: DC5V; Quiescent current: 18mA / 5V; Working current: 198mA / 5V; Module Size: 64.5x41.3x18.5mm / 2.54x1.63x0.73 inch(L * W * H), Module weight 40g / 0.09lb. Module Interface: power input: 1.DC +: module power supply positive, with the same voltage as the relay; 2.DC-: module power supply negative; Relay output: 1.NO1-NO2: relay normally open interface 2.COM1-COM2: relay common interface 3.NC1-NC2: normally closed relay interface, Package Included: 1*2-Channel Relay Control Module
