Properties
1.1 2AI RTD HF analog electronic module (6ES7134-4NB51-0AB0)
Use of Cu10 sensors
● Select "Three-wire thermal resistor" and "Cu10" at parameter assignment.
● Wire the Cu10 sensor in accordance with the three-wire connection method.
● Automatic, internal compensation of line resistance for the missing measuring line occurs
Note
Please note the following to ensure optimum line compensation in the case of Cu10:
• The sum of the cable resistance and measurement resistance must not exceed 31 Ω.
• The cable must have a resistance of no more than 8 Ω if you want to use the
