1. Switching output signals A1 / A12 between the signal
ranges 0...20 mA or 4...20 mA
The range of the outputs can be switched from 0...20 mA to
4...20 mA or vice versa depending on the positions of jumpers
J 202 and J 203 (Fig. 2).

2. Communication connector
Connect the communication connector to output A1 or A12
(Figures 5 to 8). Signals are then transferred in both directions
between the hand-held terminal and the transmitter via the
SIRAX B 811.
When using the field output A12, the 250 Ω burden connected
across output A12 in the power supply unit can be switched
in and out of circuit with the aid of jumpers J 204 and J 205
(Fig. 2).

Field output A12*
integrated 250 Ω resistor
in circuit, the burden at measuring
output A1 is reduced 250 Ω

3. Response of the output signals A1 and A12 for a fault in
the measurement/supply circuit
The response of the output signals A1 and A12 can be set with
the aid of switches 1 and 2 on the DIP switch S 201 (Fig. 2).
