MEAN WELL KAA-4R4V-S series: 4-channel KNX actuator and dimmer - KAA-4R4VS

Description

KAA-4R4VS — 4-channel KNX actuator and dimmer

MEAN WELL KAA-4R4VS combines four independent latching relays with four passive 0(1)–10 V current-sinking dimming channels. It is powered from the KNX bus and supports KNX Data Secure, linear or logarithmic dimming, panel operation, timers and scenes. This is the 16 A-per-channel version identified as available by request in the manufacturer’s model encoding.

KAA-4R4V-S family: combined catalog pages 29–38, dated 2024-10-16. The 16 A ordering option is identified on page 29; detailed tables headed 10S must not be used as its electrical specification.

Model and control functions

Parameter Details
Model identity Manufacturer ordering code: KAA-4R4V-S.
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 16 A per channel. The 16 A version is specified by request; confirm the exact supplied hardware and its complete electrical ratings before installation.
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.

Selection and installation boundaries

Parameter Details
Confirmed 16 A switching load The dedicated KAA-4R4V-S manual specifies 230 VAC and up to 3680 W ohmic load per channel for the 16 A model. Relay and dimming outputs can operate independently as configured.
Detailed ratings The catalog’s detailed electrical table is headed KAA-4R4V-10S. Its 10 A load limits, total current, inrush ratings, 50 mA output limit, cable-length allowance and unit mass are not presented as specifications for this 16 A version. Obtain the model-specific electrical and installation data before final selection.
Mechanical format The family description specifies a compact 4-unit, 72 mm-wide module for a 35 mm mounting rail. Confirm the supplied 16 A version against the family mechanical drawing and the manufacturer’s installation instructions.
Wiring principle Use the KNX+ and KNX− bus terminals with the correct polarity. For compatible 1–10 V drivers, the illustrated relay switches the AC line and the marked dimming +/− terminals connect to DIM+/DIM−. A compatible 0–10 V application may dim through the control terminals; non-dimmable loads use relay switching.
Shutter application A motor direction application uses paired relay contacts; follow the motor manufacturer’s installation and interlocking instructions.
Compatibility check Driver-count and load tables headed KAA-4R4V-10S apply to the 10 A version. Confirm the allowed driver quantity and inrush current for the supplied 16 A version; do not substitute the 10 A table.
Unit mass The catalog does not provide a separately identified unit mass for the 16 A version.
Manufacturer warranty reference The family catalog states a 3-year manufacturer warranty, subject to its applicable terms.

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.
