KLR 4 Channel Relay Module Expansion Module Low Level Dual Terminals Dual Layer PCB 5/12/24V Power
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 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 ) , 4 relay status indicator ( blue )
- Interface design humane, all interfaces can connect directly leads to very convenient
- Module size : 7.5cm * 5.0cm * 2.0cm ( L * W * H )
- With 4 fixing bolt holes for easy installation
Two module interface
- Module control side: 6 -wire interface , the interface can be directly connected to all leads , user-friendly
VCC / DC +: DC power positive (with 5V, 12V and 24V modules to choose from )
GND/DC-: DC power cathode
CL1-CL4: relay control interface , the corresponding relay is low
- Relay outputs : a 12- line interface, the interface can be directly connected to all leads , user-friendly
NO1 - NO4: normally open relay interfaces , relay before the vacant after the pull shorted with COM
COM1 - COM4: Common Interface Relays
NC1 - NC4: normally closed relay interface relay shorted with COM ago , after the pull- vacant
