Important:
the SSR relay load is powered at 24 Vac/Vdc, thus all the
other terminals in the group must be powered at 24 Vac/Vdc due to the
absence of double insulation within the group.

Tab. 3.m
If the product is installed in industrial environments (application of the EN
61000-6-2 standard) the length of the connections must be less than 30
m. This length shouldn’t be exceeded in any case.
3.7 pLAN electrical connections
If the selected system confi guration involves the connection of more than
one pRack pR300 board in a pLAN, AWG20/22 twisted pair shielded cable
must be used, with capacitance between the wires less than 90 PF/m.
The maximum length of the pLAN network is 500 m with AWG22 twisted
pair shielded cable.
The boards should be connected in parallel with reference to plug-in
connector J5 (pRack Compact) or J11 (versions S, M, L).
Important
: follow the network polarity: RX/TX+ on one board must
be connected to RX/TX+ on the other boards; the same applies to RX/TX-.
The fi gure shows the diagram for more than one board connected in
a pLAN network; this is a typical application with more than one board
connected inside the same electrical panel.

Important
: pLAN connections are possible in which more than one
board is powered by diff erent transformers; for further details see
pRack system general manual: +030220335.
3.7.1
Connecting the terminals
pRack pR300 uses PGD1 terminals, either built-in or external connected
via pLAN. Up to 2 external terminals can be connected, with pLAN
addresses 31 and 32.
The connection can be made using 6-wire telephone cables (connector
J4 for Compact models or J10 for S, M, L) or shielded twisted pair cables
with 3-pin plug-in connectors (connector J5 for Compact models or J11
for S, M, L), as shown in the table
