November 2014
Binary input device N 263E11
16x AC 12...230 V / DC 12...115 V
Installation notes
· The device can be used for permanent installation in
dry interior rooms and for insertion in control cabinets
or small distribution boards.
Υ
DANGER
· The device must only be installed and commissioned
by an authorized professional electrician.
· Unoccupied sections of DIN rail with data rail inserted
must be protected with the cover 5WG1 192-8AA01.
· When connecting the device, care should be taken that
the device can be isolated from the mains.
· The device must not be opened.
· When planning and installing electrical equipment the
relevant guidelines, regulations and specifications of
the respective country must be considered.
Technical data
Power supply
· Bus voltage: via the bus line
· Bus current: 5 mA (only half standard bus load!)
· Electronics:
- integrated power supply for AC 230V, +10%/-15%,
50 / 60 Hz
- Mains connection: 2-pole (N, L)
- power consumption: max. 1.7 W
Operating elements:
· 1 learning pushbutton:
for toggling between normal mode / addressing mode
Display elements
· 1 red LED: for checking the bus voltage and displaying
normal mode / addressing mode
· 1 green LED: for displaying the 230 V operating
voltage
1 red LED per binary input for status display;
·
LED = ON: voltage is present at the input
Inputs
· 16 inputs (each input can be connected to any phase
L1, L2 or L3 or a FELV signal)
· Input voltage: AC 12 V ... 230 V, DC 12 V ... 115 V
(U
= 0...2 V: voltage not present = log. 0;
in
U
> 9 V:
voltage present
in
Note: For DC voltage the negative pole should be con-
nected in each case to the terminal designated "N".
· Input current:
at max. AC 253 V: typically 1.5 mA (RMS)
at max. DC 127 V: typically 2.7 mA
