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.

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 Option
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
5 6 ExtINT Frontend

Controller: Extension Socket
