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: 3.1 mm; 67×44.5mm (spacing) Voltage: 5V, 12V, 24V (Optional)Module interface: 1 +:connected to the positive pole of power supply (voltage is required for relay, 5V, 12V and 24V for choice) 2-:connect to the power negative pole. 31-IN4:according to the setting of each circuit, the corresponding relay can be controlled with high or low level to suck in. Relay output terminal: with 12 lines of interfaces, all interfaces can be directly connected to lead, convenient for users to use 11–NO4: the relay normally opens the interface, and the relay is suspended before it is sucked in, and is connected with COM after it is sucked in. 2on interface of relay COM1–COM4. 31–NC4: relay normally closed interface. The relay is short connected with COM before it is sucked in and suspended after it is sucked in and low level trigger selection terminal: 1.S 1-S4 is the high-low level trigger selection of relay 1-4 channels successively; 2 and low short connection, the corresponding relay for low level trigger, com and high short connection for high level triggerage List: 1 × Relay Module
5V/12V/24V Relay module,4 Channel Optocoupler Relay Module Board High & Low Trigger (5V)
$21.99
- The relay module is isolated by a chip-type optocoupler, which has strong driving capability and stable performance. The trigger current is 5mA.
- Each path of the module can be triggered by a high or low level by a jumper setting.
- The low level triggers the relay module’s power indicator (green) and the 4-way relay status indicator (red). User-friendly interface design, all interfaces can be directly connected through the terminal leads. Four fixing bolt holes are provided.
- Fault-tolerant design, the relay will not move even if the control line is disconnected.
- The 4-channel relay module has an operating voltage of 5V, 12V and 24V.
