    一、Isolation safe Gate（Isolators）and Zener safe Gate（Barriers）     

              The definition of safety parameters: safe Gate maximum allowable voltage: Um guarantee an end safe Gate the performance of the security to allow an end to this may be the highest input voltage safe Gate the highest open-circuit voltage: Uoc in the maximum allowable voltage range at the open-end security maximum voltage safe Gate the largest short-circuit current: Isc at the highest voltage range to allow an end of the short-circuit current at the time of the maximum allowed safe Gate distributed capacitance: Ca guarantee security circumstances the nature of an end of the maximum permissible external capacitance safe Gate allow the distribution of inductance: La nature of security features to ensure the security circumstances the maximum allowable external inductor terminal.       
      
              Isolated safe Gate, Set Fence detection and operation of client-side separation of functions. From dangerous areas to safe areas to provide isolated DC power supply of the transmitter, the transmitter generated by 4 ~ 20mA. Current signal transmission from the danger zone to safe areas isolated output. Also from the security zone to standard 4 ~ 20mA current signal transmitted to the dangerous side, the implementing agencies at the scene-driven
    Power consumption: about 1.8W (24V power supply, 20mA output)
    For the transmitter voltage: ≥ 16V output load: 250 ~ 680Ω (20mA output, 250Ω load)
    The temperature drift of 0.01% F.S / ℃
    Operating temperature -20 ~ +60 ℃
    The application of field devices: Two-Wire Transmitter, Valve Positioner, electricity / gas
