What this voltage relay does in the panel
The K8AB-VS2 100/115VAC: The K8AB-VS2 is a single-function voltage sensing relay from Omron's K8AB-VS series — it monitors an AC or DC voltage against a user-set trip threshold and switches its SPDT output when the monitored voltage crosses that point. The trip range covers 1 to 150 V AC/DC, so it handles both low-level control signals and nominal line voltages within that band. The adjustable delay from 0.1 to 30 seconds lets you ride through momentary dips or surges without nuisance tripping. It snaps onto a DIN rail — standard for panel builds — and the SPDT relay contacts are rated 6 A at 250 V AC, enough to drive a small contactor coil or a pilot light directly.
Obsolete — sourcing reality for this part
Omron has marked the K8AB-VS2 100/115VAC as obsolete. For a line-down situation or a BOM fill, this part is available through independent surplus channels — quantities are lot-specific and confirmed at RFQ.
