Signal Isolation from Hazardous Areas Explosion-Proof Safety Barrier for(RS485 1 in 1 Out)

Digital to Analog ConvertersSignal Isolation From Hazardous Areas Explosion-Proof Safety Barrier For Brief description:This type of intrinsic safety barrier transmits current signals from hazardous area to safe area by isolating transmitting current or voltage signals in a circuit or two isolated circuits, and it may also provides power to transmitterson the spot. The input, output, and power supply are galvanically isolated from each other.Besides, it may be connected in a connection network in safe area via communication ports. As an intelligent product, it has an online self-diagnosis function. Customer may set the typeand the rangeof the inputor outputsignalswith a specific handheld programmer (display in Chinese) we provide.Mainly technical parameters:Explosive-proof grade:[Exia]CTransmitting accuracy:±0.1%F.S(25±2)<;30ppm/Rise time:0.5sPermissibleinput signal from hazardous area:DC:4~20mASignal type and range can be specified at your order and may also be programmed by user.Input resistance:approx. 80Available voltage:Not more than 26V for no-load, not less than 17.5V for full load.Output signal to safe area:DC current:0~10mA, 4~20mA, 0~20mADC voltage:0~5V,1~5V, 0~10VSignal type and range can be specified at your order and may also be programmed by user.Output load capacity:DC current: 0~10mA: 0~700;4~20mA: 0~350DC voltage:0(1)~5V:1M;0~10V:2MParameters certified by National Quality Supervision and Test Centre for Explosion Protected Electrical Products (CQST):Um=250VAC/DCBetween terminal 1 & 3 and terminal 4 6Uo28V Io93mA Po650mWC Co0.058F, Lo=2.8mHB: Co=0.45F, Lo=8.4mHA: Co=1.50F, Lo=22.4mHBetween terminal 1 & 2 4 5Uo50VC Co70FB Co700FA: Co=700FDielectric strength:2500V AC(Input/Output/Power supply, 1 mA leakage current, 1 minutetest time)Insulation coordination:100M (Input/Output/Power supply)Electromagnetic compatibility:IEC 61000-4Power supply:18~32V DC(Recommended voltage:24V DC)PanelLightIndicationLight indicating: PWR (green) remains shining during normal operation;Light indicating: ALM glitters (red) or remains shining when signal fault occurs.==========High-concerned chemical : NoneModel Number : Switch safety barrieris_customized : YesType : SpliceCertification : Product name : intrinsic safety barrierInput signal : 4-20mA, 1-5v, 0-10vChannel : 1 in 1 out, 1 in 2 out, 2 in 2 outInstallation : 35mm Din RailAccuracy : 0.1% FSPower supply : 18-32VDC
