Manufacturer Description


Trigger voltage: reduced 0-2.5 V, high default 3.5V-5V (If the voltage is 12V trigger, you should connect a resistor in order to cause a 5.1-6.8 k; 12V voltage trigger, you should connect a 15-22K the resistance in order to cause, otherwise it will harm the chip). Supply voltage: DC12V.
Working existing: 1 Road: 69 mA; 2-way: 119 mA; 3-way: 161 mA; 4-way: 207 mA
Tons: Air Conditioning 250V 10A or DC 30V 10A
Module user interface:
power input:
1. DC +: favorable power supply component, and also communicates to the exact same voltage;
2. DC-: negative power supply component
Trigger group:
1.CH1-CH3: 1-3 corresponds to the starting relay control terminal, support high or reduced trigger;
2. TRV +: favorable power supply external trigger, if you intend to cause an external power supply, the line between RTV + and also VCC to disconnect;
3. TRV-: external trigger negative power supply, if you intend to cause an external power supply, and also GND line RTV- to disconnect;
4.3 micro switch: relay test button representing 1-3, when the reduced level trigger reliable;
5. High/ Reduced trigger option: When linking M and also L, reduced trigger reliable; COM terminal is gotten in touch with the H, high level trigger stands.
Relay outcomes:
1.NO1-NO3: generally open relay user interfaces, relay before hanging, draw back with COM
2.COM1-COM3: Typical User Interface Relay
3.NC1-NC3: generally closed relay user interfaces, relay before with COM, after pull uninhabited.

Product Features

The module is widely applicable to the majority of electronic enthusiasts, industrial electronics and the total development of electronic products can be very good as a single-chip signal input source, you can dock with the microcontroller, or add a level drive relay, or small DC motor. Module set self-locking, interlock, trigger (jog) three options to support high and low switching. Widely used in machinery and equipment, automation equipment modification, PLC industrial control, arduino robot and other functional products. Each channel has a signal light, you can clearly see which switch in the work, work with self-locking / interlock / trigger (jog) three optional. Self-locking: press, relay pull, then click, the relay disconnected. Self-locking 3 channels do not affect each other, you can also external trigger switch (CH terminal wiring), you can choose to use high or low trigger, which can control 3 channels. Trigger (jog) is pressed, the relay pulls on, releases, and the relay is disconnected. Can also be an external trigger switch (CH terminal wiring), you can choose to use high or low level trigger
