• Electrical Protection: It is equipped with over - current and short - circuit protection for both digital and analog outputs, safeguarding the module from electrical faults.
• Quality Assurance: Through strict quality control during manufacturing and testing, the FBM204 offers reliable performance over an extended period.

6. Real - world Examples

• Small - scale Packaging Machine: In a small - scale packaging machine, the FBM204 monitors the position of packages using digital sensors (digital inputs). Based on this information, it controls the operation of the packaging mechanism through digital outputs. It also monitors the temperature of the sealing element via an analog input and adjusts the heating power using an analog output to ensure proper sealing.
• Residential Solar Power System: In a residential solar power system, the FBM204 can monitor the solar panel voltage and current (analog inputs). It can then control the battery charging process through an analog output and also turn on/off related relays (digital outputs) to protect the system from over - charging or other electrical issues.
