CBI-20 Current Loop Converter
CBI-20 equipment adapts voltage levels from any unit of measurement (voltage divisor, direct voltage, resistive
sensor, etc) and converts to a proportional value of current loop (4-20 mA) or (0-5 mA).
It is used to distributed electric power installations (RENFE,
METRO, AVE, etc) to send away voltage values. It allows to
the control centre receives in real-time the measurement of
line voltage.
