DIN-HUB
The DIN-HUB is a DIN Rail-mounted Cresnet® hub designed to facilitate
the configuration of large Cresnet networks. DIN Rail mounting enables
modular installation alongside Crestron DIN Rail lighting and automation
control modules and other third-party DIN Rail mountable devices.

3-segment Cresnet hub
32 Cresnet devices per segment
3-Segment Cresnet Hub
Cresnet is the communications backbone for Crestron lighting modules,
wall box dimmers, shade controllers, thermostats, keypads, touchpanels,
and many other devices. This flexible 4-wire bus normally supports
approximately 20 Cresnet devices without requiring a hub. Larger systems
are easily enabled by adding the DIN-HUB. The DIN-HUB features three
isolated Cresnet segments, each supporting an additional 20 devices,
allowing for systems of approximately 80 devices total (including the
"host" segment). More hubs may be added to allow up to a maximum
potential of 252 devices.
Cresnet Power Distribution
In addition to data, Cresnet carries 24 volts DC for powering the devices
connected to it. The DIN-HUB provides an easy way to manage the
distribution of power for a complete Cresnet network. Each segment can
be configured to receive its power from the "host" power source or from
another power supply. Separate power supplies may be dedicated to each
segment, or a single supply can be shared amongst multiple segments as
needed. Each segment supports up to 75 watts.
