Values for non-hazardous areas, protected against polarity reversal:
• 11.5 V ≤ Vcc ≤ 42 V (standard)
• I ≤ 23 mA
Values for hazardous areas, see Ex documentation →  61
The transmitter must be powered by an 11.5 to 42 V
with NEC Class 02 (low voltage/low current) with restricted power limited to 8 A/
150 VA in the event of a short-circuit (in accordance with IEC 61010-1, CSA
1010.1-92).

The surge arrester can be ordered as an optional extra. The module protects the electronics
from damage from overvoltage. Overvoltage occurring in signal cables (e.g. 4 to 20 mA,
