Conductor
data for con-
nection to
power supply
For short distances below 25m (75 feet)
use AWG18 conductors. For higher dis-
tances install an additional power supply
close to the AMC2 4W.
Please, calculate the voltage drop by check-
ing the conductor specifications for charac-
teristic resistance values. The voltage drop
shall not exceed 2V.
Example:
Length = 50m/165 ft
U = 12V, I = 2A, maximum V
Drop
= 2V
i.e. R
AWG18

Critical condition! Install the power supply
closer to the controller.

relay outputs
Use AWG18 conductors.
Please, calculate your voltage drop (see
above) by checking conductor specifica-
tions for characteristic resistance values.
Conductor
data analog
input
Use AWG22 conductors.
Please, calculate your voltage drop (see
above) by checking conductor specifica-
tions for characteristic resistance values.
