• Operation with current output 1: 65 to 660 mW
• Operation with current output 1 and 2: 130 to 1 320 mW
• Totalizers stop at the last value measured.
• Configuration is retained in the HistoROM.
• Error messages (incl. total operated hours) are stored.

No special measures for potential equalization are required.
Plug-in spring terminals for wire cross-sections 0.5 to 2.5 mm
• Cable gland: M20 × 1.5 with cable Æ 6 to 12 mm (0.24 to 0.47 in)
• Thread for cable entry: ½" NPT, G ½"
• Permitted temperature range: –40 °C (–40 °F) to³ 80 °C (176 °F); at least ambient temperature
+ 20 K
• A normal device cable suffices if only the analog signal is used.
• A shielded cable is recommended if using the HART protocol. Observe grounding concept of the
plant.
