Module Interface: 1. DC+: Connect the positive pole of the power supply 2. DC-: connected to the negative pole of the power supply 3. IN1-IN8: According to the setting of each way, the corresponding relay can be controlled by high or low level. Relay output: 24-line interface, all interfaces can be directly connected to facilitate user access. 1. NO1--NO8: The relay normally open interface, the relay is suspended before the suction, and it is short-circuited with COM after the suction. 2. COM1--COM8 relay common interface 3. NC1--NC8: The relay normally closes the interface, and the relay is shorted to COM before the suction is closed. High and low trigger selection: 1.> S1-S8 are the high and low level trigger selections of relays 1 to 8 in sequence; 2.> com is shorted with low, the corresponding relay is triggered by low level, and when com is shorted with high terminal, it is triggered by high level. Technical Parameters: Relay version: 5v Quiescent Current: 5mA Maximum current:190mA Trigger current: 2-4mA Low trigger voltage: 0-1.5V High trigger voltage: 2.5-5V. ? Highly Durable and 1-year ServicePlease contact us if you have any needs. Always at your service;-)

User-friendly Interface Design - All interfaces can be directly connected through the terminal block, which is very convenient. It Has a Fault-Tolerant Design - Even if the control line is broken, the relay won't actuation. "High", "Low" Level Controllable - With a jumper cap, you can choose a low level control or a high level control, allowing the relay module to adapt to more occasions. Adopts SMD Optocoupler Isolation - Use two sets of fully isolated power supply system power, to ensure that the relay in the switch will have an impact on the signal circuit and can be freely switched to high level drive mode or low level drive mode. Trigger Current is 5mA. High Quality Module - the relay module uses genuine high-quality relays. The maximum load of the frequently opened interface is: AC 250v/10a, DC 30v/10a.
