5V 2 Channel Relay High/Low Level Trigger Relay Module (Red PCB)

Description:

1) the module uses the original loose music relay, normally open interfaces Maximum load: AC 250V / 10A, DC 30V /. 10A
2) using the original Toshiba SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA
3) Operating voltage 5V
4) the power indicator (green), relay status indicator (red) 7 , the power indicator light (green), the relay status indicator (red) 7 , the module can be set by the jumper high or low level trigger
5) fault-tolerant design, even if the control line break, the relay will not move;    
6) the module size: 50mm * 41mm * 18.5mm (length * width * height) 
7) with four fixed bolt holes, holes 3.1, the interface design is user-friendly, all interfaces can be directly connected through the terminal leads, very convenient
8) Mm, spacing 44.5mm * 35.5mm

Interfaces:

1) DC +: then the power supply positive (voltage according to the relay requirements 5V) 
2) DC-: then the power supply negative 
3) IN1: 1 signal trigger side, you can set the high or low level control relay pull 
4) IN2: Trigger side, you can set the high or low level control relay pull

Relay output:

1) NO1: 1-way relay normally open interface, the relay before the pull-off, after the connection with COM1 short
2) COM1: 1 relay common interface
3) NC1: 1 relay normally closed interface, the relay before the convergence with COM1 short, pull after the floating 
4) NO2: 2 relay normally open interface, the relay before the suspension, after absorbed and COM2 shorted 
5) COM2: 2 relay common interface 
6) NC2: 2-way normally closed relay interfaces, relay before and COM2 short, after the pull-vacant

High and low trigger select side:

1) S1 for a relay high and low trigger selection;

2) S2 for the two-way relay high and low trigger selection;

3) com and low short, the corresponding relay is low trigger, com and high-side short when the high-level trigger
