4 Channel 5V/12V/24V Relay Module, High and Low Trigger Optocoupler Relay Module Board for Arduino(5V)

Fault-tolerant design This 4-channel relay module with fault-tolerant design, even if the control line is broken, the relay will not be moved. Power indicator light (green), 4-position relay status indicator light (red). Humanized interface design This 4-channel relay module with humanized interface design can connect all interfaces directly through the terminal cable, which is very convenient. Four mounting holes are provided. Standard interface that can be directly controlled by microcontroller (Arduino, Raspberry Pi, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic); Stable performance The relay board adopts photocoupler isolation, powerful driving capability and stable performance. The trigger current is 5 mA. The module can be high or low using a jumper setting trigger.The module uses real quality relay, normally open interfaces. More choices The working voltage of the relay module is 5V, 12V, 24V. Each channel of the module can be triggered by high or low level via a jumper. More choices The operating voltage of the relay module is 5V, 12V, 24V. Each channel of the module can be triggered by the high or low level via a jumper.arduino 12v arduino 4 relay optocoupler arduino 4 channels 24v relay scheda rel a 4 channels High level trigger 4 channel relay 5v 24v relay board 4 pole 12v relay module 4 channel relay board 12v 4 channel relay auf board rele arduino relay module 12v 4 channels 24v Shutdown Features: Adopt patch photocoupler isolation, strong driving ability, stable performance.

Specification: Weight: 60g/2.1oz Common interface load: AC 250V/10A, DC 30V/10A Module size (L*W*H): 73*50*18.5mm/2.9*2*0.7inch Bolt hole: 3.1mm; 67*44.5mm (spacing) Voltage: 5V, 12V, 24V (optional) Module interface: 1. DC+: connect to the positive pole of the power supply (voltage is required for the relay, 5V, 12V and 24V for choice) 2. DC-: connect to the negative power pole. 3. IN1-IN4: Depending on the setting of each circuit, the corresponding relay can be controlled with a high or low level to vacuum. Relay output terminal: with 12 lines of interfaces, all interfaces can be directly connected to the cable, convenient for users 1. NO1 - NO4: the relay normally opens the interface and it is suspended before being sucked and is connected to COM after sucking it. 2. Common relay interface COM1 - COM4. 3.NC1 - NC4: normally closed relay interface. The relay is briefly connected to COM before being sucked and suspended once sucked. High and low trigger selection terminal: 1. S 1-S4 is the high-low level trigger selection of 1-4 channel relays successively; 2. Com and short-short connection, the corresponding relay for low level trigger, com and high-short connection for high level trigger. Package List: 1 x 4 Channel Relay Module
