communication lines (fieldbus systems) and power supply is diverted to ground. The
functionality of the transmitter is not affected as no problematic voltage drop occurs.
Connection data:
Maximum continuous voltage (rated voltage)
Nominal current
Surge current resistance
• Lightning surge current D1 (10/350 µs)
• Nominal discharge current C1/C2 (8/20 µs)
Temperature range
Series resistance per wire
 16 Electrical connection of surge arrester
Grounding
The device must be connected to the potential equalization. The connection between the
housing and the local ground must have a minimum cross-section of 4 mm
All ground connections must be secured tightly.

Performance characteristics

The measured value update depends on the type of sensor and connection method and
moves within the following ranges:
Resistance thermometer (RTD)
Thermocouples (TC)
Reference temperature
When recording step responses, it must be taken into account that the times for the
measurement of the second channel and the internal reference measuring point are
added to the specified times where applicable.
• Calibration temperature: +25 °C ±3 K (77 °F ±5.4 °F)
• Supply voltage: 24 V DC
• 4-wire circuit for resistance adjustment
