2PCS KLR 2 Channel Relay Module Isolated Low Trigger Dual Terminal Dual Layer PCB 5/12/24V Power

2PCS KLR 2 Channel Relay Module Isolated Low Trigger Dual Terminal Dual Layer PCB 5/12/24V Power

Description:
- Tthe module uses genuine quality relay , normally open interfaces Maximum load : AC 250V/10A, DC 30V/10A;
- Using high-power high-voltage transistor 2907A, driving ability, stable performance ; trigger current 5mA;
- The module voltage is 5V, 12V, 24V are available ; otherwise one -way , 2-way , 4-way , 8-way modules to choose from ;
- The relay pull low , the module containing limiting resistor , low level can be GND, can MCU I / O port is set low ;
- Fault-tolerant design , even if the control line is broken , the relay will not operate ;
- The power indicator ( red ) , 2-way relay status indicator ( blue )
- Interface design humane, all interfaces can connect directly leads to very convenient
- Module size : 5.0cm * 4.2cm * 1.8cm ( L * W * H )
- With 4 fixing bolt holes for easy installation

Two module interface:
- A module control terminal ( picture above right) : 4 -wire interface , the interface can be directly connected to all leads , user-friendly
     VCC external 5V ( otherwise 12V and 24V modules to choose from )
     GND GND external
     CL1 relay a control interface , low relay
     CL2 relay 2 control interface , low relay
- B relay output ( picture above left) : 6 -wire interface , the interface can be directly connected to all leads , user-friendly
     NO1 normally open relay interfaces , relay before the vacant after short pull with COM1
     COM1 Common Interface Relays
     NC1 relay normally closed port, COM1 relay shorted before and after the pull- vacant
     NO2 normally open relay interfaces , relay before the vacant after the pull short and COM2
     COM2 Common Interface Relays
     NC2 normally closed relay interface relay short front and COM2 , pull vacant post
