Features:

• The 8550 transistor drive, drivability.
• A fixed bolt holes for easy installation.
• It has a relay status indicator led Power LED(Green), 8 relay status indicator LED(Red)
• Relay control interface by single-chip IO. Low-level suction close, high-level release.
• Easy to use, simple 3 line structure.
• It is a 5V 8 Channel Relay Module.
• The relay normally open interface maximum load: AC 250V/10A, DC 30V/10A.
• It has a trigger current of 5mA, and module working voltage of DC 5V.
• Each channel of the module can be triggered by a jumper to set a high level or a low level.
• Fault-tolerant design, even if the control line is disconnected, the relay will not move.
• With status indicator: power (green), 6-channel relay status indicator (red).
• All module size interfaces can be directly connected through the terminal block, which is convenient and practical.
