DC Voltage Level Sensor
The DC Voltage Level Sensor from Fidar Electronics reads DC voltage from 0 to 24 V and records how it sags over time. It connects to a FIDAQUIRE data logger over a daisy-chained CANopen bus.
Measures DC voltage from 0 to 24 V
Under- and over-voltage alarm thresholds
Built for battery and control-supply health
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 voltage level sensor reads the actual value from 0 to 24 V, not merely whether voltage is present. On battery systems, 12 V and 24 V control supplies and solar circuits, a slow sag is the first evidence of an ageing battery or an overloaded supply. Batteries rarely fail all at once — for weeks beforehand the on-load voltage creeps down, and a threshold catches it then rather than when service is already lost.
