Wanted a compact SESTOS D1S-VR-220 PID controller and Ink Bird SR-25 DA Solid State Relay Module enclosure, with a switch, fusebox and possibility to monitor SSR On-light.
So here it is.
The following order of assembly worked for me:
- attach all the wires to SSR (use thin ones for control clamps)
- move the SSR in (see that SSR LED is right below its opening on top) and secure it with the screw and nut (tighten the screw through the hole on the top)
- solder wire to the side contact of the fuse housing and install the fuse from the front. Use
long tweezers to screw on the nut;
- install the switch into the back part (might need a touch with a flat file to fit it in) depending on your print tolerance and pass in all the wires through the holes in the back part. The oval hole I used for the mains power, the round for the heater and the key-like hole for the thermo-pair (mine was already with contacts pressed on hence the shape of the hole to get in one contact after other);
- put a nut from inside of the side wall and screw in the M3x6 screw slightly from outside so the nut just doesn't fall out. Press in the PID controller from the front (the front opening might need a touch with a flat file to fit it in);
- solder the wire to the end contact of the fuse holder.
- connect wires to the PID controller and the solder the other ends to the switch.
Place the back part into the front part and secure it with remaining four M3x6 screws.
Case you liked / found the design useful you might decide to send me a tip - so I can raise a pint of beer to your health and blessing :)
