external Blinking lamp
Type BL4.2

The lighting angle of the LED is 35 degrees. The energy is sourced from an exchangeable type 1/2 AA 3.6V lithium battery, which is housed inside the blinking lamp. The blinking lamp type BL4.2 can be connected to any potential-free relay contact of a fault indicator. The blinking time depends on the type of potential-free relay contact. The blinking lamp is equipped with an auto-sensing system to detect the type of potential-free contact.

Permanent contact: If the blinking lamp is connected with a permanent contact, the blinking lamp will stop blinking as soon as the relay is switching back to its standby position.

Wipe contact (between 100 ms and 1 second): If the blinking lamp is connected with a wipe contact, the blinking lamp will stop blinking after a preselected time (standard value: 2 hours).
