LCN-TLK12H
The LCN-TLK12H is designed to connect conventional panels with pushbuttons and indicator LEDs. Light emitting diodes of any color can be controlled without or with integrated series resistors up to a maximum of 1.2 KOhm and 24 V, also in any combination. In addition, the LCN-TLK12H converts eight conventional floating pushbuttons to the T-connector of the LCN modules.
Up to twelve LEDs can be controlled to display any status from the bus. The brightness is adjustable in two levels. The outputs are designed as current sources, which means that each output automatically adjusts its output voltage according to the connected LED. It is possible to operate several LEDs in series at one output. The sum of all forward voltages must be less than 24 V. All outputs are short-circuit proof. The states OFF, ON, BLINKING and FLICKING are supported for LED control. The outputs work against ground.
All connected LEDs are connected with the cathode to the common terminal on the LCN-TLK12H. The outputs are designed as current sources with switchable output current of 1.8 or 15 mA. The familiar SHORT, LONG and LOS commands are available on each key. The LCN-TLK12H serves as a replacement device for the LCN-DI12 and is intended for use with the LCN-SH, LCN-HU or LCN-SHS module. The LCN-TLK12H can be used on LCN modules from firmware 10060 (June/2006).
Fields of application:
- For connecting conventional panels with pushbuttons and indicator LEDs to the LCN bus.
Not suitable for permanent contacts! In the position for 24 V LEDs, the LCN-TLK12H will be damaged if LEDs are connected without a series resistor!
