Supported Applications
The Omega DRSL-RTD Series consists of DIN rail signal conditioners designed to interface RTD inputs with SCADA systems or PLC equipment. The series converts signals from 2, 3, or 4-wire Pt100 RTDs into unipolar analog outputs suitable for industrial control environments.
Operating Conditions & Performance
The DRSL-RTD Series operates over an ambient temperature range of -25 to 70°C (-13 to 158°F) with a storage capability from -40 to 85°C (-40 to 185°F). The units support relative humidity levels of 0 to 95% RH non-condensing and carry an IP20 protection degree. Measurement ranges span -200 to 850°C (-328 to 1562°F) with a sensor current below 150 μA.
Accuracy specifications differ by model: the DRSL-RTD offers better than 0.2°C or ±0.1% of selected input range, while the isolated DRSL-RTD-ISO provides better than 0.1°C or ±0.05% of selected input range. Response time is selectable at <30 ms/300 ms (0 to 90%, 100 to 10%). The series includes broken sensor detection (>800 Ω) and shorted sensor detection (<18 Ω).
Configuration Options
The series supports configuration via DIP-switches for more than 1,000 factory-calibrated measurement ranges. Output signals are programmable to match specific system requirements.
- Output Signals: Current outputs include 0 to 20 mA and 4 to 20 mA; voltage outputs include 0 to 10 V, 2 to 10 V, 0 to 5 V, and 1 to 5 V.
- Power Supply: DRSL-RTD models accept 16.8 to 31.2 Vdc via connectors; DRSL-RTD-ISO models accept 16.8 to 31.2 Vdc via power rail or connectors.
- Isolation (DRSL-RTD-ISO Only): Provides 3-way isolation between input, output, and supply with a test voltage of 2.5 kVac (reinforced) and working voltage of 300 Vac.
- Error Detection: Sensor error detection is selectable via DIP-switch for enable or none; incorrect DIP-switch settings trigger specific out-of-range outputs.
Mechanical installation features DIN EN 60715 - 35 mm rail mounting with screw terminals accepting wire sizes from 0.13 x 2.5 mm² / AWG 26 to 12 stranded wire (torque: 0.5 Nm). The unit dimensions are 113 H x 6.1 W x 115 mm D (4.4 x 0.24 x 4.5") with an approximate weight of 70 g (0.15 lb).
Key Product Differences
The series is available in two primary configurations:
- DRSL-RTD: Non-isolated RTD input DIN rail signal conditioner.
- DRSL-RTD-ISO: Isolated RTD input DIN rail signal conditioner offering surge suppression and protection against transients and noise. This model requires the DRSL-PWR-RAIL power rail for operation when using the rail interface.
Accessories available for the series include the DRSL-PWR-RAIL (1 m length, with cover and end covers), DRSL-PCU (power connector unit, 24 Vdc/2.5 A output), and DRSL-MOD-STOP (module stop). The OMEGACARE™ extended warranty program is available for these models.
