Wires Characteristics

Use this chapter to understand the type of wire you need to use
for your plant.

Power supply wire

The TemaServer is powered at low voltage (12VDC±20% 600mA).
It can be powered at low voltage (12V
TPU03 battery-operated power supply module or by a vendor
power supply with same characteristics.
In order to determine the correct size for power cables, refer to the
below table
Make sure that the 12V cable corresponds in size to the norms
indicated in the table below (voltage cable drop max = 2V):
Cable length (m) = 2V / (0.6A x 2 x (res [Ohm/km] /1000))
LONWORKS
Data cables used with LonWorks
In a free-topology configuration or star connection, where all
device are connected starting from one single point, the total sum
of the cable lengths must not exceed 500m.
In a bus configuration or daisy chain configuration, where a device
is connected to the previous one, the bus length must not exceed
2700m.
Refer to Table 2.for sizing data cables to be used for LonWorks
connection.
