Electrical data
Terminals
Three connections for wire cross sections of up to 2 .5 mm2 (14
AWG) as connection points for power supply and
communication purposes
Grounding
Internal and external ground terminals are provided for 6 mm2
(10 AWG) wire cross sections
Power supply
The transmitter operates from 16 to 42 V DC with no load and is
protected against reversed polarity (additional loads enable
operation above 42 V DC) .
During use in Exia zones and in other intrinsically safe
applications, the power supply must not exceed 30 V DC .
Ripple
Max. 2.2 mV RMS over a 500 Ω load as per HART specifications
Load limitations
Total measurement circuit resistance at 4 to 20 mA and HART:
Voltage supply - Minimum operating voltage (V DC)
R(kΩ) =
22 mA
A minimum resistance of 250 Ω is required for HART
communication .
Analog output
Two-Wire output: 4 to 20 mA related to level / volume / flow, full
compensation for temperature effects
Displays (option)
Integrated LCD display (code L7)
Widescreen LCD display, 128 x 64 pixels, 52 .5 x 27 .2 mm (2 .06 x
1 .07 in .) dot matrix
Four keys for device configuration and management
Easy setup for quick commissioning
Customized visualizations which users can select
Totalized and actual value flow indication
Temperature and diagnostics message display, and
configuration settings
Integrated LCD display with TTG operation (code L2)
Same specifications as the integrated LCD display (code L7) An
innovative Through-The-Glass (TTG) keypad which can be used
to activate the device configuration and management menus
without having to remove the transmitter housing cover
TTG keys protected against accidental activation
