TSN light message boards are suitable for working areas of underground operations without the hazard of methane explosion and the ones with the ‘a’, ‘b’ and ‘c’ degree of methane explosion hazard as well as the ones classified to the ‘A’ or ‘B’ class of coal dust explosion hazard, at ambient temperatures from 0ºC to 40ºC, relative humidity up to 95% and the ‘C’ degree of corrosion aggressiveness to PN-71/H-04651). The device meets requirements of the EU ATEX Directive 2014/34/UE.

CHARACTERISTICS

Messages to be displayed can be selected locally by means of switches provided on the device enclosure. In case of remote control the messages are popped out from the memory upon commands received via intrinsically safe (IS) input contacts. Displaying of messages is controlled with use of voltage available in internal circuits of the device. The dot matrix display is furnished with an intrinsically safe relay output to control any other slave devices. The display can be mounted in whichever position and messages are always displayed correctly since cable inlets are provided at both at left-hand and right-hand side of the device. Displayed messages can be scrolled at two selectable speeds.
