Signal Isolators are used to isolate DC signals
and provides a repeater signal with isolation
between input, output and the instrument’s power
supply. Use of Signal Isolators / repeaters
prevent ground loop problems in complex control
loops involving multiple grounds, loop-powere
bulk supplies in 2-wie systems, unisolated cards
in PLCs etc.
Lectrotek signal isolators are available in
electronic and smart (microprocessor-based,
field programmable designs). |
