Siemens 6ES7137-6CA00-0BU0 SIMATIC ET 200SP CM 1xDALI Master Module Remote I/O Module

The Siemens 6ES7137-6CA00-0BU0 is a SIMATIC ET 200SP communication module (CM 1xDALI) that acts as a DALI V2 multi-master, controlling up to 64 DALI control gears and 63 control devices over one integrated DALI bus power supply rated 160-250 mA. It mounts on BaseUnit type U0 with color code CC20 and supports fluorescent, LED, and discharge-lamp ballasts plus presence and light sensors.

Selection Notes

The integrated DALI bus power supply means no separate 24 V DALI PSU is needed to run one line, and the 64-ballast / 63-device capacity keeps a single module sufficient for a typical open-office or warehouse lighting zone. Specify one CM 1xDALI per independent DALI line when a project needs separately addressable lighting groups on the same ET 200SP station.

Applications

Building-automation lighting control: dimming and switching DALI-compliant luminaires (fluorescent, LED, discharge, low-voltage halogen) and reading DALI pushbuttons, presence detectors, and light sensors from a SIMATIC S7-1200/S7-1500 program via ET 200SP.
