• Current module: 2 analogue outputs 0/4 ... 20 mA
• HART communication (SLAVE) via analogue output 1
NOTICE
All outgoing lines from the HART module must be screened. The screens must be applied to
the PE rail as short as possible.
NOTICE
The termination resistor (120 ) must be installed and activated on the first and the last BUS
device.
Avoid transmission line!
Terminal assignment:
1+ / 1- Analogue output 1 and HART communication (SLAVE)
2+ / 2- Analogue output 2
