Tableau adapter for eight dry contacts and twelve LEDs with common anode (+)

The LCN-TL12H converts any eight dry contacts at the T-port connection of an LCN bus module. Twelve LEDs can be controlled for indicating any status on the bus. Brightness can be set on two levels. For LED control, the states, ‘off, on, flash and flicker’ are supported. The outputs are power sources with switchable current outputs (1.8 mA/15 mA) to control the LEDs. Each key recognises the established commands: ‘LOHNG, SHORT and RELEASE’. It is designed to be used with the LCN-SH, -HU, -LD or LCN- SHS modules.


The LCN-TL12H is designed for connecting to conventional tableaus/ control panels with keys and LED indicators. Light-emitting diodes of any colour and with or without inbuilt series resistors (max 1.2 KOhm, 24 V) can be controlled in any combination. The outputs are power sources ie. Every output accordingly adjusts its output voltage to the connected LED automatically. It is possible to operate several LEDs in a row from one output (total forward voltage < 24 V!) All of the outputs are short-circuit proof. The outputs work with respect to ground/earth; all of the connected LEDs are connected to LCN-TL12H via the anode on the joint connection clip.
