请注意，不同类型的模拟输入电子模块在功能、性能和应用场景上可能有所不同。因此，在选择和使用模拟输入电子模块时，需要根据具体的应用需求和场景进行权衡和选择。同时，为了确保模块的正常运行和测量准确性，还应遵循相关的操作和维护规范。

FB201 is a relay module that can make a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity meets the specified requirements. The relay module has the control system and the controlled system, which is usually used in the automatic control circuit and plays the role of automatic regulation, safety protection, conversion circuit and so on.

Taking the 4-way relay module as an example, the FB201 is actually 4 relays combined to form 4 switches. Each switch (i.e. relay) has A moving contact and two static contacts A and B. When the switch is turned off, the moving contact contacts with the static contact B to form the upper half of the circuit, and the static contact A is called normally open contact (NO). In the circuit, the relay module is usually used as a switch, by controlling the coil current of the relay, so that the common contact is in contact with the normally open contact or the normally closed contact, thus changing the state of the circuit.

In practical applications, the FB201 can be set to a high or low level trigger by a jumper, and there are many options for operating voltages, such as 5V, 12V, 24V, etc. In addition, the relay module is also equipped with a power indicator and a relay status indicator, and the interface design is user-friendly, which is easy for users to connect and use.

Please note that the specific model, function and usage of relay modules may vary by brand and manufacturer. Therefore, when selecting and using relay modules, it is recommended to consult the relevant product instructions or consult the manufacturer to ensure correct and safe use.
