Technical Specs

Overview

The DALI Relay Module with Zero-Cross Detection effectively suppresses instantaneous surge current when the relay pulls in. It complies with DALI-2 standard, in accordance with IEC62386-101, IEC62386-102, and IEC62386-208 standard protocols. It can independently control four relays or contactors and is compatible with mainstream DALI standard protocols and master control devices, enabling non-dimmable luminaires to access the DALI lighting system. DALI addresses can be set independently, and grouping and scene control can be realized via the DALI master controller. It supports setting of DALI first address, power-on status, system failure status, and DALI scenes via the NFC Lighting APP. Each channel supports a maximum current of 12A, with a built-in independent fuse for safe operation. It features a wide voltage power supply: 100-240V~ and is DIN rail mountable, compatible with standard 35mm DIN rail.

Connection Diagram

Use the NFC Lighting APP
Scan the QR code below with your mobile phone and follow the prompts to complete the APP installation (According to performance requirements, you need to use a NFC-capable Android phone, or an iphone 8 and later that are compatible with iOS 13 or higher)

Before you begin setting the parameters of the driver, please make sure the driver is powered o .

Read/Write the LED driver
Use your NFC-capable phone to read LED driver data, then edit the parameters and they can be directly written to the driver.

Read the LED driver
On the APP home page, click 【Read/Write LED driver】, then keep the phone’s sensing area close to the NFC sensing area of the driver to read the driver parameters.

Edit the parameters
Tap [Parameter Management] to edit and set more advanced parameters such as DALI First Address, DALI Advanced Template, Power-on Status, System Failure Status, etc

Write to the driver
After completing the parameter settings, click [Write] in the upper right corner, and keep the phone’s sensing area close to the NFC sensing area of the driver, so the parameters can be written to the driver.
