Intrinsically safe railway signalers are used in control and signaling circuits of underground trains. Devices are used to display optical signals. Banners meet the requirements of the European Directive 2014/34/UE (ATEX) for equipment in group I, category M2, and can be used in methane and coal dust explosion hazardous areas of underground mines.
|ISK-SEM- used to display signals “stop” (red color), and “drive” (green color)|
|ISK-ST – used to inform about current points position, through displaying informational signals: points straight ahead (vertical line), trailing points to the left (arrow pointed to the left upper corner), trailing points to the right (arrow pointed to the upper right corner)|
|ISK-KO- used to inform about current points position, through displaying informational signals: points straight ahead (vertical line), or points to the side (a circle glowing with a white color)|
|ISK-KT- is a bilateral edition of a signaler, which was created as a combination of signalers ISK-ST and ISK-KO in one casing. Optical signal is displayed on both sides of the signaler simultaneously, one side for trailing points, other for facing points|
To every version from above there is an option to work using digital transmission. These options are labeled as ISK-*/TR (for example: ISK-SEM/TR). The signaler is equipped with two relay outputs allowing to control other signalization equipment (including other signalers).
