What is a Watchdog Relay?
The watchdog relay is used in electrical automation systems, usually to ensure the reliable operation of microcontrollers or control systems. The watchdog relay waits for a signal generated by the control system or microcontroller at regular intervals. If this signal is not received for a certain period of time or if the expected situation does not occur, the watchdog relay is activated.
The Watchdog Relay in TELEPRO Announcers is intended to increase system stability by detecting crashes (freezes) or various error conditions caused by software or hardware errors in the system. The watchdog relay is an important safety measure in electrical automation to increase system reliability and prevent unexpected situations.
