Hello,
I have been reading about color codes for machines control enclosure.
I would like to get a better idea using a new post and getting as much info as possible.
In the last 10 years, I have been using a color standard I learned since I start working on automation on my first employment, following the lead of some other experienced engineers on my group. This is the code
BLACK - AC POWER
WHITE - AC NEUTRAL
BROWN + 24VDC
BLUE 0VDC
YELLOW - PLC DIGITAL INPUT
VIOLET - PLC DIGITAL OUTPUT
ORANGE - PLC ANALOG INPUT
GREY - PLC ANALOG OUTPUT
GREEN - GROUND
RED - OTHER DC THAN 24V (12, 5, etc)
I have not found any match with this code and now, owning my company, I would like to use the best possible, such as a ISA related. (reading about ISAs)
Thanks.
