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.
