Technical data

Power supply

• 30 Vdc from bus (electronics)

• 230 Vac 50/60 Hz or 24 Vac (loads)

• Current consumption from bus < 30 mA

• Power consumption from bus 720 mW

TRIAC outputs

• Nr: 8 independent (2-pipe systems)

4 coupled (4-pipe systems)

• Max current I

: 2(1) A

max

• Max 4 electrothermal actuators in parallel for each

TRIAC output 0,5(0,3) A max

Environmental conditions

• Operating temperature: 0 ... + 55°C

• Storage temperature: - 25 ... + 55°C

• Transport temperature: - 25 ... + 70°C

• Relative humidity: 95% not condensing)

Note. For controlling loads different than electro-

thermal drives and servomotors for zone valve or

loads with rated current higher than the maximum

current, interface relays must be used.

Switching, display and connection elements

The device is provided with a membrane front keypad

with signalling LEDs and pushbuttons, programming LED

and pushbutton, a terminal for connecting the KNX bus

line and screw terminals for connecting the power supply

and the outputs.

Mounting

The device has degree of protection IP20, and is there-

fore suitable for use in dry interior rooms. The housing

is made for rail mounting according to EN 60715 in bo-

ards or cabinets for electrical distribution. The correct

mounting is when the KNX bus terminal is located at the

bottom. When installing be sure to leave accessible only

the front panel; all other sides must not be accessible.

For the installation of the device on the rail proceed as

follows:

• with the aid of a tool bring the locking device in the fully

lowered position (1);

• place the upper edge of the rear inner profile on the

upper edge of the rail (2);
