13.3 Power supply
Supply voltage
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

power supply in accordance
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).
