6.2.1 Configuration of the outputs
Current output 4 ... 20 mA / HART
In the factory setting, the flow signal is emitted via the current
output of 4 ... 20 mA. Alternatively, the temperature signal can
be assigned to the current output.
Digital output
It is possible to use software to configure the optional digital
output as an alarm, frequency or pulse output.
It is possible to use a bridge to configure the digital output as
an optoelectronic coupler output or a NAMUR output.
Fig. 29: Hardware configuration of the digital output
1 Bridge
Output configuration Bridge
Optoelectronic coupler output 1—2
NAMUR output 3—4
In the factory setting, the output is configured as an
optoelectronic coupler output.
NOTE
The type of protection of the outputs remains unchanged,
regardless of the output configuration.
The devices connected to the digital output must conform to
the current regulations for explosion protection.
Analog input 4 ... 20 mA
(for FSx450 only)
External devices can be connected to the passive analog input
(4 ... 20 mA).
The function of the analog input can be selected via the
software ("Input/Output" menu).
The analog input can be configured via the "Easy Setup" menu
or the setup menu of the device. Before starting the
configuration, select the type of the connected signal and then
select the values for 4 mA and 20 mA that correspond to the
relevant output values of the connected device.
HART Input
The HART input can be configured via the "Easy Setup" menu
or the setup menu of the device. The device recognizes the
value and the corresponding unit via the HART input.
If, for example, the pressure unit is set to psi in the setup
menu of the device but the pressure unit of the connected
pressure transmitter is set to kPa, the VortexMaster /
SwirlMaster takes the pressure unit from the pressure
transmitter.
The connected device must send the signals in burst mode. It
is recommended to use an ABB pressure transmitter from the
2600T series (e.g. 261 or 266 series) and an ABB temperature
transmitter from the TTH / TSP series. They can be switched
to burst mode using the HART command.
