### 4. Functionality
The C1602 operates as a dual-mode measurement module capable of functioning either as a frequency meter or as a pulse counter.
- Frequency Measurement Mode:
In this mode, the device measures the frequency of an incoming signal within the range of 1 Hz to 20 kHz. The input signal is processed through an isolated input stage that ensures electrical separation from the communication interface. The internal microcontroller calculates the frequency with a precision of ±0.01%, and the result is transmitted via the RS485 interface in ASCII format.
- Counter Mode:
When configured as a counter, the module counts incoming pulses up to a maximum of 10⁷ pulses. The counter input supports frequencies from 1 Hz to 10 kHz, making it suitable for event counting, flow measurement (with pulse-based flow sensors), or rotational speed monitoring.
- Communication and Data Output:
The RS485 interface allows the C1602 to communicate with supervisory systems using ASCII-based commands. This enables easy integration into existing serial networks and compatibility with standard industrial communication protocols.
- Use Cases and Applications:
- Industrial process monitoring (e.g., motor speed, conveyor belt speed)
- Flow measurement using turbine or magnetic flow sensors with pulse outputs
