1 shutter channel.

2 individual outputs*.

*Suitable for capacitive loads, maximum 140 µF.

5 analog/digital inputs.

Manual output operation with push button and LED

status indicator.

Logical functions included.

Output timing facilities.

Total data saving on power failure.

Size 67 x 90 x 35 mm (2 DIN units).

Integrated KNX BCU.

DIN rail mounting (EN 50022), through pressure.

Possibility to connect different phases in adjoining outputs.

Conformity with the CE directives (CE-mark on the right side).

Programming/test button: short press to set programming mode. If this button is held while plugging the device into the KNX bus, it enters the safe

mode. If this button is held for more than 3 seconds, the device enters the test mode.

Programming/Test LED: programming mode indicator (red). When the device enters into safe mode, it blinks (red) every half second. The manual

mode is indicated by the green color. During the start-up (reset or after KNX bus failure) and if the device is not in safe mode, it starts a blue blinking

sequence.

SAFETY INSTRUCTIONS

•Installation should only be performed by qualified professionals according to the laws and regulations applicable in each country.

•Do not connect the mains voltage nor any other external voltage to any point of the KNX bus; it would represent a risk for the entire

KNX system. The facility must have enough insulation between the mains (or auxiliary) voltage and the KNX bus or the wires of

other accessories, in case of being installed.

•Once the device is installed (in the panel or box), it must not be accessible from outside.

•Keep the device away from water and do not cover it with clothes, paper or any other material while in use.

•The WEEE logo means that this device contains electronic parts and it must be properly disposed of by following the instructions at

http://zennio.com/weee-regulation.

⚠

In order to ensure the expected status of the relays, please check that the

device is connected to the KNX bus before energizing the power circuit.
