Allen-Bradley 700HG42A24 Electromechanical Relay

Allen-Bradley 700-HG42A24 is a general-purpose open-style power relay from Rockwell Automation that packs two Form-C contacts into a single DPDT (two-pole) package for switching two circuits in a compact footprint. It features a 24 VAC coil rated for 50/60 Hz and a 40 A contact rating, making it suitable for high-current control tasks in industrial panels and automation wiring. The open-style construction is designed for panel installation without an enclosure, enabling straightforward integration with standard control systems; its DPDT arrangement supports applications such as motor direction reversal, interposing relay functions in PLC-driven circuits, and switching heating elements or other loads driven from 24 VAC control logic. Model 700-HG42A24 represents the 24 V AC coil variant within the 700-HG family, delivering reliable, two-circuit switching for demanding automation environments.
