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
产品描述 The DRSL-RTD-LP RTD input non-isolated DIN rail loop-powered signal conditioner measures a standard 2-, 3- or 4-wire Pt100 temperature sensor and provides a passive analog current output signal. The DRSL-RTD-LP provides a competitive choice in terms of both price and technology for interfacing RTD signals to SCADA systems or PLC equipment. This unit is powered by the host (output) current signal loop. Low power consumption facilitates DIN rail mounting without the need for any air gap. Easy configuration of more than 1000 factory calibrated measurement ranges is done via DIP-switches. The unit operates over a wide temperature range from -25 to 70°C (-13 to 158°F). SPECIFICATIONS INPUT Input Type: 2, 3, or 4-wire Pt100 RTD Temperature Range: -200 to 850°C (-328 to 1562°F) Sensor Current, RTD: <150 μA Sensor Cable Specifications: 50Ω per wire or 50 nF Effect of Sensor Cable Resistance (3 or 4-Wire RTD): <0.002Ω/Ω Broken Sensor Detection: >800Ω Shorted Sensor Detection: <18Ω OUTPUT Current Output Programmable Signal Ranges: 0 to 20 mA and 4 to 20 mA Range Limits (NAMUR NE43 Out of Range): Below 3.8 mA or above 20.5 mA Sensor Error Detection (Dip Switch Selectable for Enable or None): Below 3.5 mA or above 23 mA Incorrect DIP-Switch Setting Identification: Below 3.5 mA or above 23 mA Output Error Level: DIP switch selectable for upscale or downscale Load Resistance (Ω): ≤(Vsupply -3.3)/ 0.023 Load Stability: ≤0.01% of span/100Ω GENERAL Supply Voltage: 3.3 to 35 Vdc Voltage Drop: 3.3 Vdc Power Consumption: 1 W max Internal Consumption: 0.65 W max Signal/Noise Ratio: >60 dB Response Time (0 to 90%, 100 to 10%): <30 ms/300 ms (selectable, provides either fast response or signal dampening as needed). Accuracy: Better than 0.2°C or ±0.1% of selected range Temperature Coefficient: ≤±0.02°C/°C EMC Immunity Influence: <±0.5% of span Extended EMC Immunity NAMUR NE 21, A Criterion, Burst: <±1% of span (span = selected input range) ENVIRONMENTAL Operating Temperature: -25 to 70°C (-13 to 158°F) Storage Temperature: -40 to 85°C (-40 to 185°F) Calibration Temperature: 20 to 28°C (68 to 82°F) Relative Humidity: 0 to 95% RH non-condensing Protection Degree: IP20 Installation Area: Pollution degree 2 and measurement/overvoltage category II MECHANICAL Dimensions: 113 H x 6.1 W x 115 mm D (4.4 x 0.24 x 4.5") Weight: 70 g (0.15 lb) approx DIN Rail Type: DIN EN 60715 - 35 mm Wire Size: 0.13 x 2.5 mm2/AWG 26 to 12 stranded wire Screw Terminal Torque: 0.5 Nm
