DC Current Sensor
The DC Current Sensor from Fidar Electronics measures direct current in a circuit across a 0 to 5 A range. It connects to a FIDAQUIRE data logger over a daisy-chained CANopen bus.
0–5 A DC measuring range
Suited to solar arrays and battery banks
Fast response to current drops and surges
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
A DC current sensor measures direct current in a circuit across a 0–5 A range. In solar arrays, battery banks and DC equipment, current is the clearest health signal there is: a drop in charge current, an abnormal draw or a leakage path all appear in the trend long before something fails. Logging that trend gives you both the early warning and the evidence for the post-mortem.
