Power Supply

General Information
NOTE: Local wiring guidelines (e.g. VDE 0100) may take
precedence over recommendations provided in these
installation instructions.
NOTE: To comply with CE requirements, devices having a
voltage of 50...1000 Vac or 75...1500 Vdc but lacking
a supply cord, plug, or other means for disconnecting
from the power supply must have the means of
disconnection incorporated in the fixed wiring. This
means of disconnection must have a contact
separation of at least 3 mm at all poles.
All wiring must comply with applicable electrical codes and
ordinances. Refer to job or manufacturers' drawings for
details. Use a min. of 18 AWG (1.0 mm
2
14 AWG (2.5 mm ) for all power wiring.
If power is supplied via a T terminal plug, individual Excel 12
modules can be disconnected from the power supply without
disturbing the operation of other devices powered by the
same source.
Models with Line Power Supply
Models with line (i.e. 100 Vac or 230 Vac) power supply are
equipped with a built-in 24 Vac transformer, the secondary
side of which can be used to power external devices. The
max. current at the field device supply terminals and all triac
outputs together must not exceed 300 mA continuous.
NOTE: Do not connect external 24 Vac on models with line
power supply!!
These models have a long housing (180 mm). The line power
supply (230 Vac [-15% / +10%], 50/60 Hz or 100 Vac [-15% /
+10%], 50/60 Hz) is connected to terminals 43 and 44. Ter-
minals 1, 2, 22, and 23 are connected to the secondary side
of the built-in 24 Vac transformer; these terminals must not
be used for connecting an external transformer. The terminals
can be used to power e.g. an active sensor.

Fig. 5. Connection to line power supply
NOTE: The max. current at the field device supply terminals
and all triac outputs together must not exceed
300 mA continuous. Disregarding these limits can
result in the destruction of the built-in transformer.
When not supplying external devices with 24 Vac, these
models have a power consumption of under 17.5 VA.
Models with 24 Vac Power Supply
These models have a short housing (126 mm). The power
supply (24 Vac [±20%], 50 or 60 Hz) is connected to terminals
1 and 2. Terminals 22 and 23 may be used to connect further
devices to the same 24 Vac power supply.
NOTE: Do not reverse the polarity of the power connection
cables and avoid ground loops (i.e. avoid connecting
one field device to several XL12's) as this may result
in short circuits damaging your device.
