Issendorff 30239 LCN-TLK12H for 12 LEDs + 8 buttons panel adapter

The LCN-TLK12H converts eight conventional buttons (potential-free buttons) to the T-connection (button input) of the LCN modules. Up to 12 LEDs can be controlled to display any status from the bus. The brightness can be set to two levels. Can be used for all LCN modules from serial number: 10... (from June/2006). The states OFF, ON, FLASHING and FLICKERING are supported for LED control. Outputs designed as current sources with switchable current strength (1.8mA and 15mA). The familiar short, long and go commands are available on each button. It is intended for use with the LCN-SH, -HU, -LD or LCN-SHS module. The LCN-TLK12H is designed for connecting conventional panels with buttons and display LEDs. LEDs of any color can be controlled with or without integrated series resistors (max. 1.2KOhm, 24V), also in any combination. 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 on one output (sum of all forward voltages < 24V!). All outputs are short-circuit proof. The outputs work against ground, all connected LEDs are connected with the anode to the common connection terminal on the LCN-TLK12H.
