FDV0220-01
AC Voltage Detector
The AC Voltage Detector from Fidar Electronics reports whether an AC line up to 220 V is live and timestamps every loss and restore. It connects to a FIDAQUIRE data logger over a daisy-chained CANopen bus.
Detects AC voltage presence up to 220 V
Immediate power-failure alert with a timestamp
A definite two-state answer, no value to interpret
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 voltage detector reports whether a line is live. Unlike a level sensor that returns a number, it gives a definite two-state answer, which is exactly what the job needs: mains-failure alerts, proving a transfer to generator or UPS, and confirming that critical circuits are energised. Every transition is timestamped, so the outage duration stays in the record instead of relying on someone's memory.
