Technical specifications
Power supply
• Bus voltage: carried out via the bus line
• Bus current:: Notice: the device represents at least a
double bus load and takes up to 30 mA from the bus.
Outputs
• number: 8 outputs (latch relays, potential free con-
tacts)
• rated voltage: AC 230 V, 50 ... 60 Hz
• rated current: 16 A, cos phi = 1
• switching current at AC 230 V: 0,1 ... 16 A, cos phi = 1
• DC switching current:
- DC 10 ... 30 V: max. 16 A, resistive load
- DC 230 V: max. 0,18 A, resistive load
• switching characteristic: to be set in parameter list
(see application program description)
Control voltage
• 1 ... 10 V (provided by dimmable ballast)
• in case of bus voltage failure: 10 V
Control power
• dimmable electronic ballast: max 60 units
• signal amplifier: max 12 units
CAUTION
There is no protection of the control circuits against
destruction by accidental connection to AC 230 V !
Operating elements
• 1 learning push button:
for toggling between normal mode/addressing mode
• 8 slide switches for manual operation
(slide in upper position: relay contact open = OFF,
slide in lower position: relay contact closed = ON)
Display elements
• 1 red LED:
for checking the bus voltage and for displaying normal
mode/addressing mode
• 8 slide switches for displaying the switching position
per channel (see above)
Connections
• load and control circuit, physical:
insulation strip length 8 ... 9 mm
permissible conductor types/cross sections:
- 0,5 ... 4 mm² single core
- 0,5 ... 2,5 mm² flexible conductor
• load circuit, electrical:
- plain flexible conductor, min. 1 mm²:
current carrying capacity max. 6 A
- flexible conductor with terminal pin,
crimped on gas tight, min. 1,5 mm²:
current carrying capacity max. 10 A
- all other conductors, min. 1,5 mm²:
current carrying capacity max. 16 A
CAUTION
When looping through the L-conductor (connection
blocks 1 and 2, 4 and 5, 7 and 8, 10 and 11, 13 and 14,
16 and 17, 19 and 20, 22 and 23), take care that the
maximum connection current of 16 A (as governed by
the maximum permissible printed conductor load) is not
exceeded!
• Bus line:
- pressure contacts on data-rail
- screwless bus connection block,
Ø 0,6 ... 0,8 mm single core,
insulation strip length 5 mm
