รายละเอียดสินค้า
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.level.
