Controlling DALI ballasts, the C-DL-0012M module

To control lighting devices with DALI protocol (typically ballasts for fluorescent lights, etc.) there is the CIB - DALI protocol converter, the C-DL-0012S module. It is designed to connect devices with DALI protocol in accordance with the specification: NEMA Standards Publication 243-2004 Digital Addressable Lighting Interface (DALI) Control Devices Protocol PART 2-2004.

Signals from CIB buses and DALI are led by strip wires distinguished by different colours. The module is supplied from the CIB bus, and the module does not provide galvanic isolation of buses.
The C-DL-0012S module makes it possible to control independently 12 DALI elements on the bus.

Notes:

1. The type of cable used for the DALI bus is 5 x 1.5 mm², a standard cable for electricity installation (the cable contains both DALI bus and 230 VAC wires), maximum total cable length is 300m, possible topologies include linear, tree or star.

2. The DALI bus is not polarized (both signal wires DALI can be swapped in SLAVE elements), the bus is not terminated by element. The DALI bus is galvanically isolated from the supply voltage of 230 V (it meets the SELV).
