Active production — sourcing posture
The K8AK-VS3 24AC/DC: Sourced to order against the BOM quantity through independent distribution; availability and current pricing confirmed at RFQ.
Three-range voltage monitoring — what the selector means
The relay monitors single-phase AC or DC lines across three switch-selectable ranges: 20 to 200 V, 30 to 300 V, and 60 to 600 V AC/DC — the operator picks the range that brackets the nominal line voltage, not the full span. Configured for overvoltage or undervoltage detection via a front-panel DIP switch; the SPDT output (5 A at 250 VAC or 30 VDC) changes state when the monitored voltage crosses the set threshold.
DIN-rail integration and supply
The relay snaps onto a standard 35 mm DIN rail, drawing its operating power from a separate 24 VAC/VDC auxiliary supply — the monitored voltage and the relay's internal circuitry are isolated. Housing is PC and ABS; the relay occupies a single module width, fitting into a control panel alongside other DIN-rail components without crowding adjacent terminals.
