The DRSL-RTD and DRSL-RTD-ISO can be used for signal conversion of 2, 3 or 4-wire Pt100 RTD inputs into unipolar analog signals. The DRSL-RTD-ISO isolated model offers 3-way isolation between input, output and supply and provides surge suppression and protects control systems from transients and noise. 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:** 50 Ω per wire or 50 nF **Effect of Sensor Cable Resistance (3 or 4-wire RTD):** <0.002 Ω/Ω **Broken Sensor Detection:** >800 Ω **Shorted Sensor Detection:** <18 Ω ## **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 for 4 to 20 mA output; 0 mA or above 20.5 mA for 0 to 20 mA output ## **Sensor Error Detection** **(Dip Switch Selectable for Enable or None):** Below 3.5 mA or above 23 mA for 4 to 20 mA output; 0 mA or above 23 mA for 0 to 20 mA output **Incorrect DIP-Switch Setting Identification:** Below 3.5 mA or above 23 mA for 4 to 20 mA output; 0 mA or above 23 mA for 0 to 20 mA output **Output Error Level:** DIP switch selectable for upscale or downscale **Load:** 21 mA/600Ω /12.6V max - **Load Stability:** ≤0.01% of span/100Ω ## **Voltage Output** **Programmable Signal Ranges:** 0 to 10 V, 2 to 10 V, 0 to 5 V and 1 to 5 V **Range Limits (Out of Range):** Range ±2.5% **Sensor Error Detection (Dip Switch Selectable for Enable or None):** 0V or selected range + 10% **Incorrect DIP-Switch Setting Identification:** 0V **Output Error Level:** DIP switch selectable for upscale or downscale **Load:** >10 kΩ min ## **GENERAL Supply Voltage** - **DRSL-RTD:** 16.8 to 31.2 Vdc via connectors **DRSL-RTD-ISO:** 16.8 to 31.2 Vdc via power rail or connectors **Power Consumption:** 0.7 W max **Internal Consumption:** 0.65 W max **Isolation (DRSL-RTD-ISO Only):** Input/output/supply **Isolation Voltage, Test (DRSL-RTD-ISO Only):** 2.5 kVac (reinforced) ## **Isolation Voltage, Working** **(DRSL-RTD-ISO Only):** 300 Vac **Status LED:** Green LED indicates operational status of the unit and input sensor - **Normal Operation:** Flashes for 15 ms at 13 Hz rate - **Sensor Error:** Flashes for 15 ms at 1 Hz rate - **Incorrect DIP Switch Setting:** flashes for 500 ms at 1 Hz rate **Hardware Failure:** LED off **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** - **DRSL-RTD:** Better than 0.2°C or ±0.1% of selected input range - **DRSL-RTD-ISO:** Better than 0.1°C or ±0.05% of selected input range - **Temperature Coefficient:** ≤±0.02°C/°C **EMC Immunity Influence:** <±0.5% of span **1** ## **Extended EMC Immunity** **NAMUR NE 21, A Criterion, Burst:** <±1% of span (span = selected input range) ## **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 mm[2] / AWG 26 to 12 stranded wire **Screw Terminal Torque:** 0.5 Nm ## **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 **==> picture [481 x 395] intentionally omitted <==** **----- Start of picture text -----**
