Non-standard ranges: 0...1 to 0...< 20 mA
resp. live zero
0.2...1 to < (4...20) mA
Open-circuit voltage: Approx. – 7...+ 22 V
Burden voltage I : 15 V without communication
A1
10 V (15 V) with communication*
*When a hand-held terminal is connected to the field output
A12, the voltage across the burden at output A1 reduces to
10 V. Digital 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 of a jumper. The full
burden voltage of 15 V is then available at output A1 instead
of 10 V.
