• 2-wire connection
• Internal reference junction (Pt100)
• External preset value: configurable value –40 to +85 °C (–40 to +185 °F)
• Maximum sensor wire resistance 10 kΩ (If the sensor wire resistance is greater than 10 kΩ, an error message is output in
accordance with NAMUR NE89.)

13.2 Output
Output signal • FOUNDATION Fieldbus TM H1, IEC 61158-2
• Failure current FDE (Fault Disconnection Electronic) = 0 mA
• Data transmission rate, supported baudrate: 31.25 kBit/s
• Signal encoding = Manchester II
• Output data:
Available values via AI blocks: temperature (PV), temp sensor 1 + 2, terminal
temperature
• LAS (Link Active Scheduler), LM (Link Master) function is supported: Therefore, the
head transmitter can assume the function of a Link Active Scheduler (LAS) if the current
Link Master (LM) is no longer available. The device is supplied as a BASIC device. To use
the device as an LAS, this must be defined in the control system and activated by
downloading the configuration to the device.
• According to IEC 60079-27, FISCO/FNICO
Failure information Status message in accordance with FOUNDATION Fieldbus TM specification.
