KNX Consumption Interface
ZRX-KCI4SO
FEATURES
 4 channels for consumption counters (meters) with S0-pulse
outputs (UNE-EN 62053-31) *.
 Registration of consumed electric power, cost and CO
that can be split in up to 4 time intervals.
 Compliant with UNE-EN 62053-31 Class B.
 Total data saving on KNX bus power failure.
 KNX BCU integrated.
 Size 90 x 60 x 35 mm (2 DIN units).
 DIN rail unit assembly (EN 50022), with snap fit clamp.
 CE directives compliant.
*Other counters (meters) with dry-voltage output or not complying S0 standard
may also work (previous test is recommended)
1. Battery holder
5. Programming LED
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.
