Allen-Bradley 809-A01E Programmable Logic Controller Module

The Allen-Bradley 809-A01E is a Series A instantaneous trip current relay that functions as a Phase/Voltage Loss Relay for motor protection in Allen-Bradley control systems. It carries a continuous current rating of 2 A and offers a trip-current adjustment range of 1.1–3.1 A (AC) or 0.95–2.8 A (DC), with a maximum voltage rating of 600 V across AC or DC circuits. The physical form factor measures 5 × 4 × 3 inches, and the unit is documented as discontinued by the manufacturer as of February 27, 2010. This relay is designed to integrate with Allen-Bradley PLCs and related automation devices to provide rapid response to phase or voltage loss or overcurrent events in protected motors and drives.
