Only
ONE
VC3xxxX Relay Pack with remote monitoring inputs can be used under a single VTR73xxA Controller. All other slave units
must me either VC3xxxX Relay Pack(s)
WITHOUT
remote inputs. A maximum of
10
VC3xxxX Relay Packs can be used for a single
VTR73xxA Terminal Equipment Controller.
From the VTR73xxA Terminal Equipment Controller to the first VC3xxxX Relay Pack
o
Existing or new field wires
o
3 minimum required 14-22 Ga Solid or Stranded. Shield not necessary.
From the first VC3xxxX Relay Pack connected to the controller to all other VC3xxxX Relay Pack(s)
o
Existing or new field wires
o
2 minimum required 14-22 Ga Solid or Stranded. Shield not necessary.
o
Connect only 1 Power Common & 2 Tx-Rx Communication
The VTR7300 to VC3000 Transformer Relay Pack can use ANY network wiring topology as either required, being more
practical or based on availability and topology of existing wires.
