Input

Voltage drop
Standard device with 4 to 20 mA communication
Display lighting
The 4 to 20 mA current signal is the input variable.
HART ® signals are not affected.
4 to 20 mA (scalable, reverse polarity protection)
Max. input current 200 mA
12.2

Power supply

NOTICE
SELV/Class 2 device
‣
The device may be powered only by a power unit with an energy-limited circuit in
accordance with UL/EN/IEC 61010-1 Paragraph 9.4 or Class 2 as per UL 1310: ' S ELV
or Class 2 circuit' .
The process indicator is loop-powered and does not require any external power supply. The
voltage drop is1 V in the standard version with 4 to 20 mA communication and an
additional 2.9 V if display lighting is used.
