Z21 switch DECODER<\/p>\n

The Z21 switch DECODER is an universally applicable DCC switching decoder with a power output of 2 Amperes for up to 8 switches or up to 16 elements such as LEDs and bulbs.<\/p>\n

Simple connection
\nA separate DC supply can be connected so that the control centre or booster outputs are not placed under unnecessary load. If the wiring should be as simple as possible, the rail signal can also be used as a supply. In addition, the outputs are protected against overload and short-circuits.<\/p>\n

Adjustable outputs
\nEach of the 8 output pairs can be set to different modes independently of the other. These are already pre-configured and can simply be selected. Each output pair can also be individually dimmed so that lighting can be adapted precisely to requirements.<\/p>\n

It perfectly can be combined with
\n\u25a0 twin coil motors
\n\u25a0 simple light signals
\n\u25a0 all kind of illumination
\n\u25a0 the control of relays<\/p>\n

Highlights:
\n\u25a0 8 output pairs can be set independently
\n\u25a0 Optional power supply via extra applied switching power supply
\n\u25a0 Programmable with RailCom\u00ae on the main track (POM)
\n\u25a0 Short-circuit protection against overload
\n\u25a0 Updateable<\/p>\n

Adjustable modes
\n\u25a0 Standard operation – with configurable cut-in time for twin coil motors
\n\u25a0 Instantaneous operation – for switches and uncouplers. Can be be activated with a manual controller depending on the operating time (see also 10775)
\n\u25a0 Bistable continuous operation – Switching on or switching over of the lighting and signals
\n\u25a0 Bistable continuous operation – Switching on or switching over with light bulb simulation
\n\u25a0 Alternative flash
\n\u25a0 Alternative flash with light bulb simulation
\n\u25a0 Item numbers of switches 1-2040<\/p>\n","protected":false},"excerpt":{"rendered":"
