Output Modules
The alarm variant no. 2 ´Relay internally allocated´ additionally requires the
al-
location of the relays
to particular limit values (s. 10.4.3).
The variant no. 8 ´Externally Triggered´ allows a
manual triggering
of relays
through the keypad or via the interface (see manual 6.10.10.).

10.6.3 Analog Output
For analog acquisition of the selected measu-
ring point either an analog output cable ZA
1601-RK (see manual 5.1.1) without electrical
isolation or a relay trigger analog adapter ZA
8000-RTA (see manual 5.1.3) with electrically
isolated analog output can be connected to the
sockets A1 and/or A2
(2)
. All parameters for
configuration of the analog ouputs are availa-
ble in the assistant menu
Analog Output
.
The functions
Analog-start and -end
for
scaling have already been described in the
menu
Special functions
(s. 10.4).

Current output: 4-20 mA
Analog channel
In the menu
Output moduls
, the measuring point, which is output to the ana-
log output to socket A2, is displayed as analog channel. Without programming,
this is the selected channel Mxx. This adjustment in connection with a half-con-
tinuous conversion rate (s. 10.1.3) is the most favourable, because in this way,
the analog output is operated with most frequently. However, any measuring
point can be determined for the analog output via programming (see above).

Analogue channel: Mxx
