KCI
KNX Consumption Interface
ZRX-KCI4SO
Technical Documentation
FEATURES
Compliant with UNE-EN 62053-31 Class B.
DIN rail unit assembly (EN 50022), with snap fit clamp.
Size 90 x 60 x 35 mm (2 DIN units).
KNX BCU integrated.
4 channels for consumption counters (meters) with S0-pulse
outputs (UNE-EN 62053-31)
*
.
Total data saving on KNX bus power failure.
CE directives compliant.
Programming button
: short button press to set the programming mode. If this button is
held while plugging the device into the KNX bus, it goes into safe mode.
Programming LED:
programming mode indicator (red). When the device goes into safe
mode, it blinks (red) every half second.
LOW batt. LED
: if this LED is blinking in red, replace the batteries as soon as possible.
EMPTY batt. LED
: if this LED is blinking in red, the batteries are empty.
