Features Missing Fault -Tolerant Design: This 3 method relay module adopts fault -tolerant design. Even if the control wire is damaged, the relay cannot be operated and has reliability. Set Up High or Low -Level Triggers: The relay module can set high or low -level triggers. These triggers meet the needs of more trigger applications. Easy to Use: This high -voltage relay module has high efficiency characteristics, exquisite design, simple operation and extensive application. With Optocoupler Isolation: This high voltage relay module with optocoupler isolation has strong driving ability and stable performance. Direct Connection: 3 -way relay module uses the humanized interface design. All interfaces can be directly connected through the terminal wiring. This is very convenient. Specification: Item Type: 3 Channel Relay Module Specifications: 49 x 42 x 20mm Trigger Current: 5MA (Such as 3.3V microcontroller control, need to have IO push pull output function) Control Voltage: AC0-250V or DC0-30V Control Current: 0-7A Material: Electronic Components Package List: 1 x 3 Channel Relay Module Package List 1 x 3 Channel Relay Module
