Allen-Bradley 809S-DB010A1 Relay

The Allen-Bradley 809S-DB010A1 Relay is a single-phase current monitoring relay in the 809S MachineAlert family, engineered to monitor the current on a 1-phase circuit and trigger a protective action or alarm when preset criteria are reached. It accepts a 1–10 A AC/DC input via an external current transformer (such as the 809S-C1 series) and provides a single SPDT output rated to 2.5 A at 250 V AC (AC-15) for signaling or control, with common control-power options including 24/48 V AC/DC and 230 V variants. The compact enclosure measures 22.5 x 80 x 99.5 mm and is designed for DIN-rail mounting in industrial panels; the 809S family supports multiple voltage inputs and is used for under- and overcurrent protection of motors and loads in process and plant applications.
