Typical Application
This module is perfectly suited for redundant temperature monitoring:

Input: A Pt100 RTD is connected to measure temperature in a process vessel or pipeline.

Processing: The conditioner measures the RTD resistance, linearizes the signal according to the Pt100 curve, and converts it.

Output 1: A 4-20 mA signal representing the temperature is sent to the primary control system (e.g., DCS) for monitoring and control.

Output 2: An identical 4-20 mA signal is sent to a safety system or data recorder for backup or compliance logging.
