DX-19 Signal Relay Product Introduction (English)
The DX-19 flashing signal relay is a control device specifically designed for AC/DC signal circuits, widely applied in power system secondary loops and industrial automation. It integrates IC technology with RC circuits and incorporates compact intermediate relay components. Upon energizing the operating coil, the contacts periodically open and close to generate rhythmic flashing light signals, making it ideal for visual alert applications. The product supports multiple rated voltages including DC 220V/110V/48V and AC 220V/50Hz, with actuation voltage not exceeding 80% of rated value and stable flashing frequency maintained at 40-80 cycles per minute. Featuring standardized housing, it offers three installation options: embedded rear-wiring, protruding front-wiring and rear-wiring configurations for flexible integration. The contact system handles 0.5A DC or 1A AC load under 250V, meeting general signal circuit control requirements. Designed for reliability, all conductive parts withstand 2000V power-frequency withstand voltage between components and enclosure, with insulation resistance over 300MΩ. Typical applications include fault indication in protection devices and status alarms in control systems, capable of driving up to 30 LED lamp circuits per unit. 6722
