Use
The controller (type PIC16F630) can be programmed in Microchip
®
PIC™ Assembler and other compilers.
The compiler HEX file can be programmed using one of our PIC™ programmers K8048, K8076, VM111, VM134.
The programming method whit the controller remaining onto the PCB is called in-circuit (via the ICSP connector).
The controller chip can also be removed out of the IC socket and be inserted into an external programmer.
Using the in-circuit method implies that no input may be activated during the programming process. The output status is also
undetermined. Make sure to avoid damages due to an uncontrolled energizing of the relays.
Please visit

and download an exemplary program with Assembler source code.
JUMPERS JP1 to JP4:
These jumpers allow you to limit the maximum output current so as to connect a LED directly to the output.
A 1K resistance will be placed in series with the output when you remove the jumper. This value is the value needed to
activate a standard LED at a power voltage of 12V.
I led = (U – Uled) / Rv
(12 – 1.6) / 1000 = 0.0104
10mA.
