FDV0220-02
DC Voltage Detector
The DC Voltage Detector from Fidar Electronics reports whether a DC circuit up to 60 V is energised and raises the alarm the moment it is not. It connects to a FIDAQUIRE data logger over a daisy-chained CANopen bus.
Detects DC voltage presence up to 60 V
Immediate supply-loss alert with a timestamp
Covers 12, 24 and 48 V industrial supplies
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 detector reports whether a DC circuit up to 60 V is energised. On −48 V telecom sites, 24 V control panels and battery systems a supply loss is usually silent: nobody notices until a service drops, and by then nobody knows when it went. This detector raises the alarm at the moment it happens and records exactly when.
