5.2 Electrical data for operation in zones 2, 21, 22
5.2.1 Devices with HART protocol
When operating in potentially explosive areas, observe the following electrical data for the transmitter
signal inputs and outputs. For the current output version (active/passive), see the identification marking
in the device's terminal compartment..
Model: 406012/1-1, 406013/1-1, 406015/1-1, 406016/1-1, 406018/2-1 (single-compartment hous-
ing),
406019/2-1 (single-compartment housing)
All inputs and outputs are galvanically isolated from each other and from the voltage supply. .
Termi-
nal Function
31/32 Current/HART output - The current output is available in "active" or "passive" mode.
97/98 PROFIBUS-PA (PA+/PA-) or FOUNDATION Fieldbus (FF+/FF-) – according to IEC 61158-2
51/52 Digital output DO1 active/passive - Function can be configured locally as "Pulse output" or "Binary out-
put". The default setting is "Pulse output".
81/82 Digital input/contact input - Function can be configured using software on-site as "External output
switch-off", "External counter reset", "External counter stop", or "Other".
41/42 Digital output DO2 passive - Function can be configured using software on-site as "Pulse output" or "Bi-
nary output". The default setting is "Binary output", flow direction signaling.
PA Potential equalization (PA)
FE Functional ground (only for transmitters outside potentially explosive area)
IMPORTANT (NOTE)!
The transmitter and sensor housing must be connected to the potential equalization PA. The operator
must ensure that when connecting the protective conductor (PE), no potential differences can occur be-
tween the protective conductor (PE) and potential equalization (PA).
A temperature of 70 °C (158 °F) is assumed at the cable entry for the Ex calculations. The cables used
for the voltage supply and the signal inputs and outputs must therefore have a minimum specification of
70 °C (158 °F).
