DALI Switch Interface

The Prolojik PC734 is a compact DALI addressable interface for the connection of 2 way light switches.

Designed for easy installation, with quick connect terminals, the Prolojik PC734 switch interface has been developed to complement Prolojik addressable lighting control modules and hubs. The interface has been designed for minimum installed depth, making it ideal for installation into a switch backbox.

As standard the PC734 is supplied with coloured cables 100mm long 0.5mm² which can be easily removed if required



For the connection of up to 2 volt free light switches; 2 latching switches, or 2 center-biased two-wayand off retractive switches.


2-pole terminals(for DA, DA connections)

3-pole switch terminals

Switch 1 – COM / 1 / 2

Switch2 – COM / 3 / 4

Humidity: 10% - 90% non-condensing

Conformity & Standards
EMC immunity EN50082-1
EMC emissions EN50081-1
DALI & NEMA compliant
IEC Standard 62386-102
NEMA Standard NS243-2004
Supports DALI 2 & 3 byte protocol

11mm deep x 40mm long x 21mm wide


Requires 35mm deep backbox or greater

Switch line should be kept to an absolute minimum, and must be below 2 metres

Switch line requires screened cable

DALI is a non isolated bus.

Switches used with this device must therefore be mains rated

Commissioning Aids
Remote addressing from PC101

Power Consumption
4mA nominal consumption at 15V DALI bus voltage
