Technical specifi cations
power supply:
rated power:
Use a class 2 safety transformer with a rating of least 15VA.
Power supply connections to the pGD2/3 ("PGD")
Observe the following rules:
• The power supply terminals on the PGD are called G and G0. The connection is made using 2-pin removable terminals.
Possible cross-section of the wires: 0.5 to 1.5 mm
• A dedicated 800 mAT fuse must be installed externally between the power supply and terminal G;
• If the transformer that supplies the pGD is the same that also supplies "pCO" devices, then terminal G0 on the pGD must be
connected to terminal G0 on the pCO;
Important:
• if the secondary of the power supply transformers needs to be earthed, then terminal G0 must be earthed, both on
the pCO and the pGD.

Interfaces

RS485 serial for communication with pCO controllers, via 3-pin removable terminals. Use a shielded twisted pair cable,
AWG20-22, maximum length 200 m. The total length of the network must not exceed 500 m. The capacitance between the wires
must not exceed 90 pF/m.
Note: to reach the maximum length use a bus layout with branches that do not exceed 5 m.
