The HD Bus Terminals are available in various versions, such as 16-channel terminals for digital inputs or outputs, 8-channel terminals for digital inputs or outputs with 2-wire connection, or “multi-tasking” combination terminals with eight digital inputs and eight digital outputs, offering the user a high degree of flexibility.
There is a broad range of applications for HD Bus Terminals in building automation: for example, 8-way buttons with integrated LEDs, for indicating the switching statuses, can be wired completely to a single 12 mm Bus Terminal. Eight thermal drives can be controlled completely by a single 12 mm output terminal using the 2-wire technique. On the input side, eight window or door contacts can be connected to one HD Bus Terminal using the 2-wire technique. With the compact I/O modules, the user saves valuable installation space in the control cabinet and the cost per channel is lowered significantly. A further advantage is the simplification of system assembly. Despite the high packing density, the convenient layout of the connection points is retained.
