Description:
4 Channel 5V 12V 24V Relay Module Board Shield With Optocoupler Support High and Low Level Trigger
Module description:
- 1. The module uses genuine high-quality relays. The maximum load of the normally open interface: AC 250V / 10A, DC 30V / 10A;
- 2. SMD optocoupler isolation, strong driving ability and stable performance; trigger current 5mA;
- 3, the module working voltage is 5V, 12V, 24V to choose from;
- 4. Each channel of the module can be triggered by setting high or low level through jumpers;
- 5. fault-tolerant design, even if the control line is broken, the relay will not operate;
- 6. Power indicator (green), 4-way relay status indicator (red)
- 7. The interface design is user-friendly, all interfaces can be directly led out through the terminal block, which is very convenient
- 8. Module size: 73mm * 50mm * 18.5mm (length * width * height)
- 9. with 4 fixing bolt holes, 3.1mm holes, pitch 67mm * 44.5mm
Module interface:
- 1. DC +: Connect to the positive pole of the power supply (the voltage is according to the relay requirements, there are 5V.12V and 24V options)
- 2. DC-: connect to the negative pole of the power supply
- 3. IN1-IN4: According to the setting of each channel, the corresponding relay can be controlled to be activated at high or low level.
Relay output:
- 12-wire interface, all interfaces can be directly connected and led out, which is convenient for users
- 1. NO1--NO4: relay normally open interface, the relay is suspended before the pull-in, shorted to COM after the pull-in
- 2.COM1--COM4 relay common interface
- 3. NC1--NC4: relay normally closed interface, the relay is short-circuited to COM before pull-in, and left floating after pull-in
High and low level trigger selection terminal:
- 1. S1-S4 are the high and low level trigger selection of relays 1 to 4;
- 2. When com and low are shorted, the corresponding relay is triggered at low level, and when com and high are shorted, it is triggered at high level.
