What the Rako DIN-LINK is
The Rako DIN-LINK bridges the DIN bus and the Rako wired network and powers both from its 24V DC input. Every DIN installation needs one. It plays the role that the RAK-LINK plays for RAK systems.
Where it sits in a Rako system
DIN modules such as the DIN-4T connect on the DIN bus. Wired devices connect through a DIN-CONNECT on its RJ45 port, and a WK-HUB connects to its RJ11 port. A WK-HUB is required to program a wired DIN system. See the Rako DIN range.
Ratings and limits
- Up to 64 DPU: DIN-4T, DIN-8S and DIN-4C use 8 each; DIN-DLI uses 16
- Up to 30 wired devices via RJ45; 1 device (Hub or accessory) via RJ11
- Over-current, over-voltage, under-voltage lockout, reverse-polarity and soft-start protection
Power and connection
It needs 24V DC from a DIN-PSU-100. It has a 4-way DIN bus terminal, an RJ45 port and an RJ11 port. Rako's DIN-LINK instruction manual covers installation, which should be done by a competent electrician.
Fitting
Mounts on a top-hat DIN rail (IEC/EN 60715) and is 9 DIN modules wide (157 x 110 x 59mm, 270g), with 150mm vertical clearance required. It operates from +2°C to +40°C.
Questions
What power supply does the Rako DIN-LINK need?
A DIN-PSU-100, providing 24V DC.
How many DIN modules can one DIN-LINK run?
Up to 64 DPU: for example eight DIN-4T, DIN-8S or DIN-4C modules, or fewer with a DIN-DLI.
Do I need a WK-HUB with the DIN-LINK?
Yes, for programming. Rako states a WK-HUB is required to program a wired DIN system.
