Purpose:
JX-3/R flash relay is mainly used on various embedded screens. When the protected system fails and the main protection relay is activated, various light signals are controlled through the flash relay.

Relay model name:



Working Principle:
Relays use integrated circuits, resistors, and capacitors to form an RC oscillator, which is controlled by a control circuit to start oscillating. The required oscillation frequency signal is selected by the internal frequency divider of the integrated circuit. Once this signal is amplified, it is output by the relay contacts.

Usage:
