产品详情
参数
包装
  • 2, 3 or 4-Wire Pt100 RTD Input
  • Powered By the Host (Output) Current Signal Loop
  • High Accuracy Better Than 0.2°C or 0.1% of Selected Range
  • Slimline 6 mm (0.24") Housing
  • Excellent EMC Performance and 50/60 Hz Noise Suppression
  • Fast Response Time < 30 ms/300 ms (Selectable)
  • Pre-Calibrated Temperature Ranges Selectable via DIP-Switches

  • The DRSL-RTD-LP RTD inputnon-isolated DIN rail loop-poweredsignal conditioner measures astandard 2-, 3- or 4-wire Pt100temperature sensor and providesa passive analog current outputsignal. The DRSL-RTD-LP providesa competitive choice in terms of bothprice and technology for interfacingRTD signals to SCADA systems orPLC equipment. This unit is poweredby the host (output) current signalloop. Low power consumptionfacilitates DIN rail mounting withoutthe need for any air gap. Easyconfiguration of more than 1000factory calibrated measurementranges is done via DIP-switches. Theunit operates over a wide temperaturerange from -25 to 70°C (-13 to 158°F).
