RM1-HB 110to480VAC 0.5A Relay
Technical Specifications

• Function: Solid-state bridge rectifier designed for electric motor braking systems. 
• Input Rating Range: 110V to 480V AC (Compatible with standard industrial 3-phase and single-phase voltages). 
• Max Continuous AC Input Current: 0.5A (Note: Some alternative variants handle up to 1.0A or 3A peak). 
• Operation: It converts the alternating current (AC) line voltage directly into direct current (DC) to rapidly engage or release the motor brake mechanism when the power state changes. 

Typical Applications

• Rossi Gearmotors: Commonly integrated directly into the terminal box of Rossi gearboxes and brake motors. [1]
• Industrial Automation: Used in conveyors, hoists, cranes, and packaging machinery where rapid, reliable motor stopping is critical.
