2pcs KLR 1 Channel Relay Module Isolated Low Trigger Dual Terminal Dual Layer PCB 5/12/24V Power

2pcs KLR 1 Channel Relay Module Isolated Low Trigger Dual Terminal Dual Layer PCB 5/12/24V Power

Note:when you order please note the power you need ,we have 5V,12V,24V power you can choose ,thanks

Description
- The 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 operating voltage 5V, 12V and 24V module and another choice ;
- 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 ) , 1 relay status indicator ( blue )
- Interface design humane, all interfaces can connect directly leads to very convenient
- Module size : 4.8cm * 2.6cm * 1.8cm ( L * W * H )
- With 4 fixing bolt holes for easy installation

Two module interface
- A: module control side, there are 3-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 control interface, low relay
- B: relay output , 3 -wire interface , the interface can be directly connected to all leads , user-friendly
    NC normally closed relay interface relay shorted with COM ago , after the pull- vacant
    COM Relay Common Interface
    NO normally open relay interfaces , relay before the vacant after the pull shorted with COM
