Regent ER651-20 Solid-State Machine Tool Relay

The Regent ER651-20 Solid-State Machine Tool Relay (ER65120) is a load-switching device designed for machine-tool control with a 1 A load rating and a 24 VDC control input. As part of Regent Controls’ ER651 family, it is built for direct interchangeability with conventional electromechanical relays, preserving familiar control-panel layouts, front-through wiring, and captive terminals for easy replacement. The solid-state design delivers fast, quiet switching and long life by eliminating moving parts, making it well suited to repetitive sequencing, clutches, solenoids, small motors, brakes, and other tool- or automation-loads in industrial equipment. This model is available in variants with different coil voltages to match diverse control systems, including 24 VDC (ER651-20 family) and 115 VAC coil configurations (ER651-20-115) in the broader ER651 line. Depending on configuration, the ER651 family supports multiple pole arrangements—up to four poles in some models—to suit different wiring and control schemes. Applications commonly include machine sequencing, timing, and safety-related control where reliable, maintenance-free switching is required, and where the device is expected to replace traditional relays without altering panel layouts. In short, the ER651-20 offers Regent’s solid-state reliability for machine-tool control, pairing a compact form with a clear, readily integrable control interface and a 1 A switching capability appropriate for smaller automated loads.
