Introduction
KTH 15 intrinsically safe automatic telephone made by modern electronic technology ,all integrated circuit is a kind of communication terminal of high performance and high reliability . configured with KTA17 safe coupler, it can connect with up ground switch or dispatch master station to constitute underground production dispatch communication system.
Features
1) KTH 15intrinsically safe automatic telephone is not only used underground ,but also hard places with high temperature, high moisture, strong pollution;
2) The material of cover is static-free, with features of waterproof, dustproof, anticorrosion and the protection degree IP54;
3) Installation ,desk-top ,hanging type optional, by adopting the newest electronic switch structure, all the components is fixed strongly.
4) The keyboard is totally sealed with noctilucence and there are keys for emergency call, hang up and recall;
5) With communication distance adjustment switch, it is possible to adjust the switch to improve the communication effects according to the distance between the telephone and dispatch master station for the situation of communication distance long, insulation of wire not good.
Usage Condition
1) environment temperature: -5°C~+40°C;
2) average relative moisture: ≤95%(25°C);
3) atmospheric pressure: 80kPa~106kPa;
4) noise: ≤75dB;
5) the place with explosive mixture, but without corrosion gas for insulation ;
Technical Data
1) Ex-mark: ExibI;
2) Dial type: P/T compatible;
3) Structure type: hanging type;
4) Feed voltage:DC58 or AC58;
5) Intrinsically safe parameters:
a) max input DC voltage:<=58V;
b) max input DC current:<=35mA;
c) max input bell voltage:<=58V, frequency: (25±3)Hz;
d) max input bell current:<=35mA;
e) volume of bell:>=80dB;
f) longest communication distance:10km;
g) net weight:3.3KGS;
