Regent Controls PR523-120 Solid-State Clutch Brake Relay

Regent Controls PR523-120, marketed as the ClutchBraker120, is an all-solid-state power-supply relay that directly energizes 90 VDC clutch or brake coils from a 120 VAC logic signal, eliminating the need for additional interfacing relays. Its logic-level input is PLC-compatible, enabling direct connection to PLC outputs, sensors, or photoelectric controls, proximity sensors, or transistor-driven interfaces. Key features include a compact DIN-rail or panel-mount package, LED indicators for each load, and an adjustable switching-time delay to minimize overlap between clutch and brake, which helps extend mechanical life on high-speed machines. Regent Controls specifies this model for 120 VAC logic and 90 VDC clutch/brake applications, making it suitable for material handling, indexing tables, winding and packaging equipment, conveyors, film feed, and label feed systems; the unit is designed to drive the load with minimal wiring and without external interface modules. Note that distributors list PR523-120 as a ClutchBraker120 variant and indicate the model has been discontinued by the manufacturer, so availability may be limited and, where encountered, replacement or cross-reference guidance should be consulted with Regent Controls or authorized distributors.
