Allen-Bradley 813S COWEM Current Monitor Relay

Allen-Bradley 813S-COWEM Current Monitor Relay is a solid-state line current monitor relay from Rockwell Automation designed to sense current on a connected load and drive a control signal for protection or signaling in industrial panels. It is specified for 120 VAC control power and monitors loads in the 5–10 A range, making it suitable for mid‑size motor circuits and other current‑based protection applications. As a member of the 813S family of motor protection devices, the COWEM variant emphasizes current monitoring within the solid‑state family, offering fast response and reliable operation in harsh environments while maintaining compatibility with other Allen-Bradley components and PLCs. Typical uses include detecting abnormal current conditions to trigger protective actions, interlocks, or signaling within a Rockwell Automation control scheme, helping safeguard motors and loading equipment. The 813S-COWEM model is identified in Rockwell literature as a current monitoring option within the 813S lineup, distinct from the 813S voltage‑monitoring variants, and is positioned for integration in industrial control panels that rely on Rockwell Automation hardware and software ecosystems.
