DIN-BLOCK
The DIN-BLOCK is a DIN Rail-mounted Cresnet® distribution block designed 
to facilitate the termination of Cresnet wiring at a head end or distribution 
point. DIN Rail mounting enables modular installation alongside Crestron 
DIN Rail lighting and automation control modules and other third-party 
DIN Rail mountable devices. 
 
Features 
 12 port Cresnet distribution block 
 Detachable screw terminal blocks for easy termination and 
troubleshooting
 Split power bus for flexible 24V power distribution 
 Diagnostic LEDs for network power and data 
 Passive device — no programming required 
 
Cresnet Distribution 
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 allows for combinations of homerun 
and daisy-chain wiring, and the DIN-BLOCK provides a simple means for 
connecting up to 12 separate Cresnet cables as part of any sized network. 
 
Cresnet Power Distribution 
In addition to data, Cresnet carries 24 volts DC for powering the devices 
connected to it. The Cresnet ports on the DIN-BLOCK are arranged into two 
separate power groups, providing an easy way to manage the distribution of 
power for a complete Cresnet network. A separate power supply may be 
dedicated to each group, or a single supply can be connected to both groups 
as needed. Each group supports up to 75 watts. 
DIN-PWS50
The DIN-PWS50 is a 50 watt Cresnet power supply module designed to 
snap onto a standard DIN Rail installation. DIN Rail mounting enables 
modular installation alongside Crestron DIN Rail lighting and automation 
control modules and other third-party DIN Rail mountable devices. All 
wiring connections are made using screw terminals positioned along the 
top and bottom, clearly accessible from the front for easy installation and 
servicing. Three Cresnet power ports are provided.
