Installation notes
The device can be used for permanent installation in
dry interior rooms and for insertion in control cabinets
or small distribution boards.
V
DANGER
Never connect an AC or DC voltage to an input for a
potential-free contact (this will damage / destroy the
input / device and impress this voltage on the bus).
Basic insulation for 250 V has to be kept when con-
necting the potential-free contacts to the terminals.
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: carried out via the bus line (DC 21...30 V,
SELV)
Bus current: 5 mA (only half a standard bus load ! )
Electronics:
- integrated power supply for AC 230 V, + 10 % /- 15 %,
50/60 Hz
- Mains connection: 2-pole (N, L)
- power consumption: max. 1.6 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: contact is closed.
Inputs
8 inputs, potential-free (with basic insulation 250 V
against each other and against the EIB)
Detection of the switching status of a floating contact
connected to an input by means of voltage pulses gen-
erated by the device:
- pulse voltage when the contact is open: typ. 15 V
SS
- pulse current when the contact is closed: typ. 0.45 A
SS
Input signal delay until transmission of first bus tele-
gram:
- after closing the contact: 100 ms
- after opening the contact: 100 ms
Contact closed time: min. 100 ms
Contact open time: min. 100 ms
max. detectable switching frequency: 5 Hz
Input function: to be set in the parameter list
Max. length of connecting cable with wires twisted in
pairs: 100 m
Connections
Mains connection and inputs:
