Vinny,
What is the maximum length of the PAB bus for all devices?
Someone I know has set up a large coral holding facility with 5 x 60m runs of trays (10 systems, 2 per row) that they would like to monitor and automate. I have been helping them come up with some configurations options.
They would like to run controllable LED lighting along the length as well as monitor power draw and dose to each of the seperate systems (two per row) and as such there is a need to place an expansion box at each end a row plus one in the middle.
note: Most likely centrally mounted power hub PAD 6D would be used rather than powerbar, but other than that what follows is representative.
The minimal component layout is as follows
Row 1 PL3.1Tex -> 2m cable -> PAB Doser -> 2m cable -> PAB PowerBar -> 30m cable -> ExpansionBox -> 2m Cable -> PAB PowerBar -> 30m cable -> PAB Doser -> 2m cable -> PAB PowerBar -> 2m Cable -> ExpansionBox -> 80m Cable to Row 2
Row 2 Expansion box -> 2m cable -> PAB Doser -> 2m cable -> PAB PowerBar -> 30m cable -> ExpansionBox -> 2m Cable -> PAB PowerBar -> 30m cable -> PAB Doser -> 2m cable -> PAB PowerBar -> 2m cable -> ExpansionBox -> 80m Cable to Row 3
Row 3 Expansion box -> 2m cable -> PAB Doser -> 2m cable -> PAB PowerBar -> 30m cable -> ExpansionBox -> 2m Cable -> PAB PowerBar -> 30m cable -> PAB Doser -> 2m cable -> PAB PowerBar -> 2m cable -> ExpansionBox -> 80m Cable to Row 4
Row 4 Expansion box -> 2m cable -> PAB Doser -> 2m cable -> PAB PowerBar -> 30m cable -> ExpansionBox -> 2m Cable -> PAB PowerBar -> 30m cable -> PAB Doser -> 2m cable -> PAB PowerBar -> 2m cable -> ExpansionBox -> 80m Cable to Row 5
Row 5 Expansion box -> 2m cable -> PAB Doser -> 2m cable -> PAB PowerBar -> 30m cable -> ExpansionBox -> 2m Cable -> PAB PowerBar -> 30m cable -> PAB Doser -> 2m cable -> PAB PowerBar -> 2m cable -> ExpansionBox
This would involve a total of 670m of PAB cabling, will this work?
Im talking to them to move to something less massive/complex so that its easier to monitor and manage, i.e. each row having a seperate controller, so that there is redundancy and maximum values for various things are not challenged (number of sockets for example) etc.
But this question is simply to get an answer on what the maximum length of the PAB bus.
thanks
