A module description:
1. The module adopts genuine high-quality relay, and the maximum load of normally open interface is 250V/10A AC and 30V/10A DC:
2. The patch optical coupler is used for isolation, which has strong driving ability and stable performance; Trigger current 5mA;
3. The working voltage of the module is 5V/12V/24V.
4. The module can set high level or low level trigger through jumper;
5, fault-tolerant design, even if the control line is broken, the relay will not act;
6. Power indicator (green) and relay status indicator (red)
7. The interface design is humanized, and all interfaces can be directly connected through the terminal, which is very convenient.
Module interface:
1. DC+: Connected to the positive pole of the power supply (voltage according to relay requirements)
2. DC-: Connected to the negative pole of the power supply
3. IN: High or low level control relay pull-in relay output:
1. N0: Relay normally open interface, relay hangs in the air before being attracted, and is shorted with COM after being attracted
2. C0M: Relay common interface
3. NC: Relay normally closed interface. The relay is shorted to C0M before being attracted, and is suspended after being attracted.
High and low level trigger selector:
1. When the jumper is shorted to L0W, it is triggered at a low level:
2. When a jumper is shorted to a high level, it is triggered at a high level.
The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.
In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.
All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.
This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
