2.1.1.3 Description
The analog output module 750- and its variation create a standardized signal
of 4-20 mA.
The module has two output channels and enables, for example, the direct
wiring of two 2-conductor actuators to the connections AO 1 and 0V or AO 2
and 0V. The signals are transmitted via AO 1 or AO 2.
The channels have a common ground and a shield (screen) (S). The shield
(screen) is directly connected to the DIN rail. A capacitive connection is made
automatically when snapped onto the DIN rail.
The input signal is electrically isolated and will be transmitted with a
resolution of 12 bits.
The operational readiness and the trouble-free internal data bus
communication of the channels are indicated via a green function LED.
Any configuration of the output modules is possible when designing the
fieldbus node. Grouping of module types is not necessary.
The voltage supply is done via the field supply.
The field side supply voltage of 24 V for the output module is derived from an
adjacent I/O module or from a supply module. A capacitive connection of the
supply potential to the adjacent I/O modules is made automatically via the
internal power contacts when snapping the output modules.
Warning
The maximum current of the internal power jumper contacts is 10 A. When
configuring the system it is important not to exceed the maximum/sum
current. However, if such a case should occur, another supply module must be
added.
Note
Use an appropriate supply module (e.g. 750-602) if an electrically isolated
voltage supply is required!
The analog output module 750-554 and its variations can be used with all
couplers/controllers of the WAGO-I/O-SYSTEM 750 (except for the economy
types 750-320, -323, -324 and -327).
