Module de relais 4 canaux 5V / 12V / 24V, carte de module de relais optocoupleur déclencheur haut et bas pour Arduino(5V)

Fault-Tolerant Design: This 4-channel relay module features a fault-tolerant design; even if the control line is broken, the relay will not be activated. It includes a power indicator (green) and a 4-position relay status indicator (red).

Humanized Interface Design: This 4-channel relay module's user-friendly interface allows for direct connection of all interfaces via the terminal cable, which is very convenient. Four mounting holes are provided. It features a standard interface that can be directly controlled by a microcontroller (Arduino, Raspberry Pi, 8051, AVR, PIC, DSP, ARM, MSP430, TTL logic).

Stable Performance: The relay board uses optocoupler isolation, providing strong driving capability and stable performance. The triggering current is 5 mA.

The module can be set high or low using a jumper trigger. The module uses a genuine, high-quality relay with normally open interfaces. The operating voltage of the relay module is 5V, 12V, or 24V. Each channel of the module can be triggered by a high or low level via a jumper. Each channel of the module can be triggered by a high or low level via a jumper.

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 terminal of the power supply (a voltage is required for the relay; 5V, 12V, and 24V are available).

2. DC-: Connect to the negative terminal of the power supply.

3. IN1-IN4: Depending on the setting of each circuit, the corresponding relay can be controlled with a high or low level for activation.

Relay Output Terminal: With 12 interface lines, all interfaces can be directly connected to the cable, convenient for users.

1. NO1 - NO4: The relay normally opens the interface and is suspended before activation. It connects to COM after activation.

2. Common interface of the relay: COM1 - COM4.

3. NC1 - NC4: Normally closed relay interface.

The relay is briefly connected to COM before being activated and suspended once activated.

High and Low Trigger Selection Terminal:

1. S1-S4 is the high-low trigger selection for relays 1-4 channels successively;

2. COM and short-short connection, the corresponding relay for the low-level trigger, COM and high-short connection for the high-level trigger.
