Output signals A1 and A12
(see Section "Electrical connections")
The output signals A1 and A12 can be load-independent DC
voltages U
or currents I
.

A1 and A12 are not electrically insulated; the same value is avail-

*When a hand-held terminal is connected to the field output A12,
the voltage across the burden at output A1 reduces to 10 V. Dig-
ital communication requires a minimum burden at output A1 of
250 Ω. A 250 Ω resistor is therefore connected across the output
circuit. If the load of the burden across output A1 already exceeds
250 Ω, the resistor can be disconnected by changing the position
