Relay-Trigger Modules - Ahlborn ALMEMO 2590-2 Operating Instructions Manual

14. Output modules

14.2 Relay-trigger modules

While V5 modules permit only one module (relay, trigger input, or analog out-
put) with just one function variant for all elements, the ALMEMO
have several V6 output modules connected and all elements can be individual-
ly configured in all their function variants. Old input and output cables (ZA
1000-EAK) can be reconfigured using the AMR-Control software to be compat-
ible with V6 functioning. The new relay trigger analog adapter ZA 8006-RTA3
(see Manual 5.1.2/3) offers up to 10 relays for driving peripheral equipment.
Or, instead of the relays, 2 trigger inputs and up to 4 analog outputs can also
be provided (see 14.3). These modules can be connected equally well to out-
put socket A2 or output socket A1 (2). To ensure that all elements are ad-
dressed, each of these sockets has been assigned 10 port addresses :
Socket Connection
A1 V6 output modules connected to socket A1
A2 V6 output modules connected to socket A2
The individual elements of the output modules
can be selected in the main menu
and programmed in their functions as
MODULES
follows (see Manual 6.10.9):
First select the port by pressing :
e.g. port 0 at socket A2 (port address 20):
The element concerned is recognized :
Relay type NO (normally open) :
Relay type NC (normally closed) :
Relay type (changeover):
The relay switching mode can be configured on the following variants;see 8.5 :
0: Alarm, if one channel of all is faulty
2: Alarm of a programmable channel
3: Alarm, if one limit value - max of all is overshot 3: Summated alarm - max
4: Alarm, if one limit value - min of all is undershot 4: Summated alarm - min
8: Relay driven via interface or keypad
Variant 2 ´Assigned internally´ also requires the assignment of relays to cer-
tain limit values; (see 12.12.2).
For the purposes of detecting power failure it is an advantage if relays are
driven on an inverted basis; without current an alarm status applies automati-
cally. The function variants are therefore also provided on an inverted basis.
Inverted relay control :
e.g. variant 2 inverted :
The activation mode and actual contact status resulting from relay type and
driving mode are displayed in the next line.
