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(25ºC±2ºC)Influence of ambient temperature:<30ppm/ºCRise 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. 80ΩAvailable 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: 0~700Ω;4~20mA: 0~350ΩDC voltage:0(1)~5V:≥1MΩ;0~10V:≥2MΩParameters certified by China National Quality Supervision and Test Centre for Explosion Protected Electrical Products (CQST):Um=250VAC/DCBetween terminal 1 & 3 and terminal 4 & 6:Uo=28V, Io=93mA, Po=650mWC: Co=0.058μF, Lo=2.8mHB: Co=0.45μF, Lo=8.4mHA: Co=1.50μF, Lo=22.4mHBetween terminal 1 & 2, 4 & 5:Uo=5.0VC: Co=70μFB: Co=700μFA: Co=700μFDielectric strength:≥2500V AC(Input/Output/Power supply, 1 mA leakage current, 1 minutetest time)Insulation coordination:≥100MΩ (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.FAQQ: Are you trading company or manufacturer ?A: We are a manufacturer, committed to producing high accuracy, long-term stability, cost-efficient pressure/level/temperature measuring instruments.Q: What's your quality control system?A: All of our products are completed with temperature compensation and 48 hours aging test before shipment.
