AC Current Sensor
The AC Current Sensor from Fidar Electronics measures RMS alternating current from 0 to 5 A, and reaches much larger feeders through a current transformer. It connects to a FIDAQUIRE data logger over a daisy-chained CANopen bus.
Measures RMS alternating current, 0 to 5 A
Extendable to higher currents with a CT
Fast response to load changes and current swings
RJ45 output on a CANopen bus
Daisy-chains up to 64 sensors per card
Works with the FBC0232-01 card and FIDAQUIRE logger
Up to 500 m of bus at 125 kbit/s
Power and data share one cable
An AC current sensor continuously measures the RMS current flowing in a line and hands it to your monitoring system for logging, trending and alarms. It reads 0–5 A directly, and with a current transformer the same sensor covers feeders of tens or hundreds of amps — the CT ratio is applied in software so the reading comes back in the line's real amps. Current is the most telling health signal an electrical load has: its trend shows a motor's loading, whether a machine is actually running, and the onset of mechanical wear well before it stops the line.

Installation
Mount the sensor on the panel wall or rail and keep the signal cable away from power conductors so induced noise does not disturb the reading.
