Analog Wiring

[MegakriLL]

I need to connect a analog amplifier with the analog input 0-10V on my Siemens 1200 PLC (located inside the same cabinet as plc, about 40 cm between).

do i need a shelded cable?

or just RK0,75mm2?

do i use any special color on 0-10V?

I wouldn't think it was necessary to use shielded cable for that length unless there is a great deal of High voltage 3 phase or such right on top of it.

Most Companies use BLUE for DC+  wiring some also use it for the negative side but many use grey. 

I wouldn't use black outside of a shielded cable because alot of companies use black for H1 [incoming L1 from outside the panel to the breakers and such].

If you don't use screening you can always twist the two cables tightly together.  It helps minimise pickup.  Obviously not as good as full screening though.

I am sure you get away with not using shielded wiring.

But why???

Never Have used it inside a panel.
