Protection module charge pump LinuxCNC sequence switch UPDI ATTINY402 (PM21.1)

Description

PROT
ECTION MODULE - a charge pump for LinuxCNC with sequential switching and
UPDI ATTINY402
(
PM21.1)
PM21.1 module
enables power protection
(i.a. spindles, stepper motors e.t.c.) against accidental switching on.
The module also allows for a sequentially control the activation of  individual power parts by limiting the current consumption, which gives you the option of using the module as a power supply switch.
OPERATING PRINCIPLE:
After appearing a 500 Hz frequency with 2% tolerance
at the IN input
,  the high state will gradually appear at the 1-4 outputs by
every 5 seconds
.
After the frequency decay (e.g. disabling LinuxCNC or computer failure) all outputs will switch to low state after approx. 3 milliseconds.
The module is programmable
- if you are interested in programming other options, please contact us before ordering.
-> Programmable
ATTINY402  by UPDI interface.

ADVANTAGES:
-
small size (this board is very compact, it doesn't take much space)
- milled edges (they're not sharp to the touch, it provides safety using)
- quick and easy installation
-
comfortable
mounting holes
- POLISH PRODUCTION
