Model and control functions
Parameter
Details
Model identity
Manufacturer ordering code: KAA-4R4V-10S.
Supply method
Powered by the EIB/KNX bus; no additional power supply is required.
Relay arrangement
Four independent latching relays with four dimming-control channels. Select the required switching, dimming or shutter application in ETS.
Rated channel selection
10 A per channel. Observe the load-category, total-current and inrush limits below.
Configuration and manual operation
Configure the application with ETS. Panel buttons provide manual operation and status indication. Time and scene functions are programmable.
KNX Data Secure
The device certificate attached to the unit is required for the first secure configuration. After commissioning, remove it from the device as recommended and store it securely. Use a compatible application database and specialist KNX commissioning knowledge.
Dimming interface
Four DC 0(1)–10 V passive current-sinking outputs for compatible LED drivers or electronic ballasts. This is a control interface, not an LED load power supply.
Dimming response
Linear or logarithmic dimming curves are selectable in ETS. Each channel has a green status LED.
Communication functions
Central manual enable, switching, absolute dimming and operation status; channel switching/status, relative and absolute dimming, scenes, automatic functions, blocking and staircase-light functions. The communication-object table also provides prewarning and permanent ON; use the application database for the applicable objects and flags.

Manufacturer installation instructions
Parameter
Details
Terminal torque discrepancy
The current catalogue states 0.8 Nm, while the instruction manual recommends 5 kgf-cm (4.4 lb-in) at the screw terminals. These values differ. Confirm the instructions for the supplied hardware revision with MEAN WELL before tightening.
KNX terminal and cable layout
Use 0.6-0.8 mm solid-wire diameter at the KNX bus terminal and strip 5 mm. The manual lists 350 m maximum from the bus supply to the furthest device, 700 m between devices and 1000 m total bus-line segments; the stated maximum 256 devices remains subject to actual system power and topology.
Secure commissioning
For KNX Data Secure, use ETS5 version 5.5.0 or later, the device-specific FDSK from its label and the required project security configuration. The manual also allows unsecured operation when deliberately configured; secure capability alone does not mean the installed system is operating securely.
Relay and dimming terminal preparation
The manual specifies 0.5-4.0 mm2 solid or 0.5-2.5 mm2 stranded conductors (12-26 AWG), stripped 6.5 mm, for the relay and dimming screw terminals, with a 3 mm slotted screwdriver. Confirm the applicable terminal torque separately.
Passive dimming interface
The DC 0(1)-10 V dimming outputs are passive. Use the appropriate wiring diagram for a compatible 1-10 V or 0-10 V LED driver. A non-dimmable driver can use relay switching only; a shutter motor requires its separate relay wiring arrangement.
