Properties
1.1 2/4AI RTD ST analog electronic module (6ES7134-4JB51-0AB0)
Using PTC resistors
PTCs are suitable for temperature monitoring and as thermal protective devices for complex
drives and transformer windings.
● Select "Two-wire resistor" and "PTC" when configuring:
● Connect the PTC in accordance with the two-wire connection method.
● Apply PTC resistors of type A (PTC thermistors) in accordance with DIN / VDE 0660,
● If the diagnosis "Overrun/underrun" is enabled, a diagnosis "Lower limit exceeded"
● Sensor data for the PTC resistor:
