Frequently asked questions
What is the trip range and delay on the K8AB-AS2 100/115VAC?
The trip current range is 0.1 to 8 A AC/DC. The adjustable delay timer spans 0.1 to 30 seconds, allowing you to ignore inrush spikes on motor or transformer starts.
How can I order the K8AB-AS2 100/115VAC and check availability?
Submit an RFQ with your target quantity. We source this obsolete relay through independent distribution — current pricing and stock position are confirmed at quote time, not listed on the page.
What this relay does in the panel
The K8AB-AS2 100/115VAC: The adjustable delay timer (0.1 to 30 seconds) lets you ride through inrush or short-duration transients without nuisance tripping — useful on compressor or conveyor starts where the start current spike would otherwise trigger the alarm. SPDT relay contacts rated 6 A at 250 VAC give you one N.O. and one N.C. set — wire the N.O. to a PLC input for remote monitoring and the N.C. in series with the motor contactor coil for hardwired shutdown.
Mounting and supply voltage
Snaps onto standard 35 mm DIN rail — the housing footprint matches the K8AB family, so it swaps in without redrilling the panel backplate. Supply voltage is 100 to 115 VAC nominal — confirm your control transformer taps before wiring; a 120 VAC primary winding with a 110 V secondary tap is the typical match. Operating temperature range -20°C to 60°C means it lives in an unheated electrical room or inside a NEMA 12 enclosure without forced cooling.
Lifecycle reality — obsolete, sourced to order
Omron lists the K8AB-AS2 as obsolete. No official successor part number is published in the available records. For a line-down situation or a BOM that requires this exact order code, we source through independent distribution channels — quantities are confirmed at RFQ, and we can quote against your annual volume or a one-off emergency buy. If you're designing a new panel, consider a current-monitoring relay from Omron's current-production K8AB series with a similar trip range and supply voltage — the DIN footprint and terminal layout are consistent across the family.
