3. BBO 467 012 7 1 Summary STS43 STS43R provides a fully floating DC power supply to two wire 4 20mA transmitter of danger zone and recurs current signal in two output floating loops to drive the two loads of safety zone The product meets the relevant regulations of GB3836 1 2000 Part 1 of Explosive Gas Atmosphere Electrical Equipment General requirement and GB3836 4 2000 Explosive Gas Explosion proof Electrical Environment Equipment Intrinsic Safety T and obtained a national explosion inspection agency issued certificate of explosion proof products can be applied to different intrinsic safety and explosion proof system 2 Technical Specifications Channel Single channel Fully floating Area of transmitter zone0 IIC T4 6 danger zone Zone 1 Group A Danger zone Safety zone output Signal range 4 20mA Safety zone load resistance 0 5500 Output resistance of loop gt 1MQ Danger zone input Signal range 4 20mA Voltage Distribution at 20mA gt 15 5V Conversion precision 0 1 Temperature drift lt lpA C LED display Green Source indication Source 20 35 VDC Power consumption 20 mA signal at 24V 110mA 2 1 Conditions of Use a Environmental temperature 10 degrees 50 C b Relative humidity lt 90 25 C c Atmospheric pressure 80kPa 110kPa d No explosive dangerous gases E Safety Barrier should be installed in the security zone An end of the maximum allowable voltage of 25
4. rinsic ends blue and non intrinsic ends yellow of the isolate barrier is prohibited from wrong and confusion The intrinsic safe leads should use the blue as the marking intrinsic leads and non intrinsic leads should be installed separately in the leads slot and use different casing tubes The intrinsic safety side of isolate barrier is not allowed to have a mixture of other power including other power supply with intrinsic safety current When the isolate barriers are with concentrated layout it should make the intrinsic side adjacent with the intrinsic side and non intrinsic side adjacent with the non intrinsic side to avoid the confusion On the separate power supply debugging of isolate barrier it is important to pay attention to the model power polarity voltage grading and connector tab on the shell of isolate barriers It is forbidden to test the insulation between the terminals of isolate barrier with insulation ohmmeter to check the insulation of the system lines it should disconnect all isolate barriers at first otherwise it would cause the fuse of internal instant fuse If the internal module of isolate barrier is damaged and needs replacement it is needed to return to the factory for repairing The repaired isolate barriers should have a comprehensive re examination before being put into operation The installation use and maintenance of isolate barrier should strictly abide by the relevant contents of GB3836 15 2000 Part
