Din Rail Case
Manufacturer: https://www.okw.com
Part: Railtec B - 4 TE / https://www.okw.com/de/Railtec-B/B6503121.htm?var=c9f11140-cb2e-11e3-89f9-00163e72470b
The case can be ordered directly from OKW. But keep in mind that you should reach 100EUR netto to overcome additional fees.
Mechanical
[2mm space to outer case edge] [1,6mm inner OKW Railtec cover] [6,1mm free space to inner OKW Railtec lid] → top-edge inner lid to top-edge frontend pcb = 7,7mm [1,6mm Frontend PCB] [15mm M3 hex spacer] [1,6mm Controller PCB] [18mm M3 hex spacer] [1,6mm Application PCB] [3,5mm screw pin on black OKW Railtec base plate]
Recommendation for tactile push button Frontend PCB: 9,5mm height. THT: http://www.reichelt.de/Kurzhubtaster/TASTER-3301B/3/index.html?ACTION=3&LA=2&ARTICLE=27893&GROUPID=7587&artnr=TASTER+3301B&SEARCH=%252A SMD: http://www.reichelt.de/Kurzhubtaster/TASTER-9319/3/index.html?ACTION=3&LA=2&ARTICLE=44518&GROUPID=7587&artnr=TASTER+9319&SEARCH=%252A
5mm LED PCB spacer for 3mm THT LEDs: http://www.reichelt.de/Zubehoer-fuer-LEDs/MEN-2818-3045/3/index.html?ACTION=3&LA=446&ARTICLE=62820&GROUPID=3044&artnr=MEN+2818.3045&SEARCH=led%2Babstandshalter → the LED protrudes about 2mm out of the cover lid. → Use 4mm led spacer to reduce this to 1mm
You can use a plain PCB with silkscreen printing and wholes to create a nice looking cover, that sits on the OKW Railtec lid. This will also fill the remaining space to the outer case edge on top of the OKW lid.
Interconnections
Controller: Application Socket
The controller PCB must use a 2x4 or 2x8 micromatch socket.
Pinout:
| Description | Pin | Pin | Description |
| GND / KNX GND | 1 | 2 | GND from 24V Input |
| VCC | 3 | 4 | 24V from 24V Input |
| SDA / IO0 | 5 | 6 | IO3 |
| SCL / IO1 | 7 | 8 | ExtINT APPL / IO2 |
| Option0 | 9 | 10 | Option7 |
| Option1 | 11 | 12 | Option6 |
| Option2 | 13 | 14 | Option5 |
| Option3 | 15 | 16 | Option4 |
Option0..7: Freely selectable, depends on the controller. If not used at all: Stick to Pin1..8 and apply an 2x4 micromatch socket only.
IO0..IO3: Freely selectable, but:
SDA/SCL: This pins must have I2C capabilities
ExtINT: This pin must have interrupt capabilities
24V Input: 24V DC supply voltage from separate socket with white/yellow wire pair
GND: relative to VCC
GND 24V: relative to 24V DC Input
VCC: 3.3V or 5V, depending on the controller, if possible, selectable wire jumper/solderjumper
Controller: Frontend Application Socket
| Description | Pin | Pin | Description |
| GND | 1 | 2 | SDA |
| VCC | 3 | 4 | SCL |
| unused/reserve | 5 | 6 | ExtINT Frontend |
