Talk:Current loop

Two-way radio use - proposal to delete
This section seems to be about historical and proprietary equipment, far removed from the process control mainstream use. I propose deleting this to prevent confusion. Dougsim (talk) 18:46, 4 October 2016 (UTC)


 * Process control instrumentation is no more contemporary than its use for remote radio station control. It's near-obsolete for everything now, including instrumentation. So this should stay. Andy Dingley (talk) 20:37, 4 October 2016 (UTC)


 * 4-20mA current loop is still in wide use. Dougsim (talk) 21:28, 4 October 2016 (UTC)


 * Many things are both obsolete, yet still in use as legacies. Current loop (a single low-bandwidth signal per copper wire!) is hardly the choice for new work. Andy Dingley (talk) 22:39, 4 October 2016 (UTC)


 * 4-20mA is not legacy. This manufacturer guidance note is dated 2015 Dougsim (talk) 02:11, 5 October 2016 (UTC)
