Integrator's note
The K8DT-AS1TD is a current-sensing relay for AC/DC circuits, monitoring 2-500mA with an adjustable delay from 0.1 to 30 seconds. NPN output (solid state) signals undercurrent or overcurrent conditions. Runs on 24VAC/DC and snaps onto DIN rail — a clean fit for a panel that already has a 24V control bus.
What the ratings mean
Trip range of 2-500mA AC/DC; delay adjustable 0.1 to 30 Sec for transient rejection. Supply voltage at 24VAC/DC means it shares the common panel control voltage; no separate DC supply needed if AC control is present. Solid-state output switches fast with no contact bounce, suitable for direct PLC input or small relay loads.
