To prevent a risk of injury due to electrical shock
and/or damage to device due to short-circuiting,
low-voltage and high-voltage lines must be kept
physically separate from one another.
Further, to prevent a risk of short-circuiting and
damage to your unit, do not reverse the polarity of
the power connection cables, and avoid ground
loops (i.e., avoid connecting one field device to
NOTE: All wiring must comply with applicable electrical
codes and ordinances. Refer to job or manu-
facturers' drawings for details. Local wiring guide-
lines (e.g., IEC 364-6-61 or 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
24 VAC Terminals for Auxiliary or Field Devices
All 24 VAC auxiliary power supply terminals support 1 x 2.5
or 2 x 1.5 mm
24 VAC Models
The 24 VAC models are powered via a black removable
terminal plug (terminals 3 and 4), thus allowing daisy chain
wiring of the power supply. See also Fig. 1. These terminals
support 1 x 2.5 mm
or 2 x 1.5 mm

Communication / Signal Terminals
All other communication / signal terminals (except for the
Sylk Bus – see Table 10 on pg. 15) support 1 x 2.5 mm

wiring. Two wires with a total thickness of 2.5
(14 AWG) can be twisted together and connected
using a wire nut (include a pigtail with this wire group and
attach the pigtail to the individual terminal block).
Deviations from this rule can result in improper electrical
contact. Local wiring codes may take precedence over this
WEB-RL6N, WEB-RS5N (24 VAC)
Power via terminals 3,4: 24 VAC 20%, 50/60 Hz.
Max. current consumption (when unloaded): 300 mA.
Max. current consumption (when loaded):
A 24 VAC model is "loaded" when, besides the inherent load
(300 mA), an additional sum load resulting from max. 600
mA is applied to the 24 VAC output terminals. The max.
unloaded output voltage at terminals 3 and 4 (WEB-RS5N)
or terminals 5 and 6 (WEB-RL6N), respectively, is identical
with the output voltage of the external supplying
transformer. A maximum 22VA rating transformer is
needed when loaded.
All models can be used with freely programmable appli-
cations. The application engineer performs this task on a
PC on which the Niagara software program has been
installed (see also corresponding Technical Literature
listed in Table 11 on pg. 18).
The application supports a variety of actuators.
• Analog 0(2) - 10 V
• Staged actuators
• 6-way valve actuators
A variety of sensors (e.g., room temperature sensors, supply
temperature sensors, condensation switch, window
sensors, occupancy sensors, card readers, etc.) may be
used to optimize control quality.
