The AA-card (AA = output analogue) pro-
vides the processing results via up to 10
analogue currents in the range of 0␣ …␣ 20␣ mA.
The scaling, as well as the definition as rising
or falling characteristics is made via the PC
with VVO.
Indicating instruments, recorders, controllers
or PLC-systems are connected to these
outputs.

The AD-card (AD = output DISBUS) brings
max. 15 measured values to one DISBUS-
line. Up to 30 VEGADIS 174 indicating instru-
ments can be connected to this line.
AR-card
The AR-card (AR = output relay) provides 10
relay outputs with floating spdt. The following
instruments can be connected:
- acoustic or optic signallers
- magnet valves
- contactors
- etc.
The AR-card is suitable for the output of level,
individual or collected fault signals. The
switching condition of each relay is indicated
via a two-coloured LED in the front facia. This
LED lights depending on the parameter ad-
justment of the relay as level contact or as fail
safe relay. Each fail safe relay can be indi-
vidually co-ordinated to one or several meas-
urement loops. The definition of the relay
function, the switch points, as well as the
LED-colour is made via the PC with VVO.
AT-card
The AT-card (AT = output transistor) provides
10 floating outputs via NPN-transistors. Bi-
nary input cards of PLC-systems are con-
nected.
The application possibilities and the signalling
of the switching condition correspond to the
AR-card.
