It is used as a power supply device, signalling, intrinsically safe barriers, data acquisition controller together with remote sensors of various types, placed both in non-explosive and explosive areas. To form the supply voltage of sensors-analysers DAT-M, alarm devices STM-30-10 - STM-30-16, sensors-gas-analysers DAH-M, DAK, DAM, potentiometric ion activity analysers AP430-02 and other compatible devices measuring DC input signal; to issue the measured information via digital communication channel RS-485 on request from an external device and light alarm when the set threshold values are exceeded/lowered with simultaneous switching of "dry" relay contacts.
