2Pcs DC 5V 4 Channel Relay Module Board Shield with Optocoupler Isolation Suport High/Low Level Trigger Relay
2Pcs DC 5V 4 Channel Relay Module Board Shield with Optocoupler Isolation Suport High/Low Level Trigger Relay
Description: Maximum load: AC 250V/10A, DC30V/10A SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA The module voltage 5V Each channel module can be set high or low triggered by jumper Fault-tolerant design, even if the control line is broken, the relay will not operate Power indicator (green), 4 relay state indicator (red) Interface design user-friendly, all interfaces are available through the wiring terminal direct connection leads, very convenient Module size: 73mm 50mm 18.5mm (L W H) 4 mounting bolts holes, hole 3.1mm, spacing 67mm 44.5mm High and low level trigger selection: S1:It is option switch for channel 1 relay. S2:It is option switch for channel 2 relay. S3:It is option switch for channel 3 relay. S4:It is option switch for channel 4 relay When the Com and low in short circuit, the relay is low level trigger, com and high end in short circuit, the relay is high level trigger. Input Interface: 1. DC+: to connect the power positive 2. DC-: to connect the power negative 3. IN1-IN4:can set the high or low level control relay Output Interface: 1. NO1-NO4: relay normally open interface, suspend the relay before pulling, then short connect with COM 2. COM1-COM4:relay common interface 3. NC1-NC4: relay normally close interface, short connect the relay with COM before pulling, then suspend Package Inlcude: 2pcs 5V 4 Channel High and Low Level Trigger Relay (Red Board)
