What the Rako DIN-8S is
The Rako DIN-8S is an 8-channel switching module for DIN rail enclosures. For dimming, use the DIN-4T; for blinds, the DIN-4C. The RAK8-S is the wall-mounted RAK equivalent.
Where it sits in a Rako system
It sits on the DIN bus behind a DIN-LINK, which links the DIN modules to the Rako wired network and is powered by a DIN-PSU-100. Programming is done in RASOFT Pro and needs a WK-HUB. Wireless keypads can control it through a WK-HUB or WRB100. See the Rako DIN range.
Ratings and limits
- Mains LED: 300W per channel
- Incandescent: 600W per channel
- Transformer: 300W per channel (cos φ 0.6 or better)
- Motor: 1A per channel (1/3 HP fan)
- Total rated current: 10A
Power and connection
It runs from 230V AC (+10% / -15%) and connects to the DIN bus by a 4-way screw terminal. It uses 8 of the DIN-LINK's 64 DPU. Rako's DIN-8S 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, 265g), with 150mm vertical clearance required. It operates from +2°C to +40°C.
Questions
Can the Rako DIN-8S dim lights?
No. It switches non-dimmable loads. Use the DIN-4T for dimming.
What can each DIN-8S channel switch?
Up to 300W of mains LED, 600W incandescent, 300W of transformer load or a 1A motor, within 10A total.
What does the DIN-8S need to work?
A DIN-LINK with a DIN-PSU-100, and a WK-HUB for programming.
