Posted 8 Dec 2011 A quick question for you'all. On your standard Belden Blue hose 9463, which conductor is the positive one? Blue or transparent? Many thanks in advance, building a new machine and don't want to bother the plant EE. -Emach Share this post Link to post Share on other sites
Posted 8 Dec 2011 (edited) I don't know which is positive or negative never put a meter on it. But the color coding per the manual is just the opposite for Remote I/O and DH+. see pictures below. But it really does not matter wire is wire. It just helps to keep DH+ and Remote I/O separate. Picture on left is Remote I/O picture on right is DH+ Edited 8 Dec 2011 by Mickey Share this post Link to post Share on other sites
Posted 8 Dec 2011 A bit of clarification, I am using it as a shielded 4-20mA wire in my machine to bring the signal from an isolator to an AB analog input card. Share this post Link to post Share on other sites
Posted 8 Dec 2011 I normally use clear/white for positive and blue for negative. Share this post Link to post Share on other sites
Posted 8 Dec 2011 That's an expensive cable for 4 to 20ma. Must have lots of it around. Share this post Link to post Share on other sites
Posted 9 Dec 2011 Sure is. I do not get too 'precious' about 4-20ma cables and normally use a cheap, screened cable 7/0.20 size. Use the same stuff for my Modbus RTU and CompoNet comms as well unless it is a long run when I use 0.75 sq. mm stuff. Share this post Link to post Share on other sites
Posted 9 Dec 2011 I always use black/red or clear/black and black is ALWAYS negative. Just like your car. Share this post Link to post Share on other sites
Posted 21 Dec 2011 You hit that spot on. One of our facilities had several manufacturing lines that were removed in the last few years. I have huge storage bins full of blue hose. Share this post Link to post Share on other sites
