Typical Application
This module is perfectly suited for flow or speed measurement with enhanced diagnostics:

Input: A turbine flow meter generates a frequency signal (e.g., 0-1000 Hz) proportional to flow rate.

Processing: The conditioner isolates the frequency signal, measures its rate, and converts it linearly to a 4-20mA output.

Output: A 4-20 mA signal representing the flow rate or speed is sent to the DCS or PLC for control.

Alarm 1: The first relay triggers a HI alarm if the flow rate exceeds a safe maximum.

Alarm 2: The second relay (potentially a dedicated diagnostic alarm) triggers if the input signal is lost (burnout) or a fault is detected.
