DRSL-SP2-Rptr-Spltr

Supported Applications

The Omega DRSL-SP2 is an isolated DIN rail signal conditioner and splitter designed for process signals. It provides galvanic isolation and conversion of voltage or current inputs, specifically intended for use with SCADA systems or PLC equipment.

Operating Conditions & Performance

The unit operates within an ambient temperature range of -25 to 70°C (-13 to 158°F) and supports storage temperatures from -40 to 85°C (-40 to 185°F). It functions in relative humidity conditions of 0 to 95% RH non-condensing. The device achieves an accuracy of ≤±0.05 % of span with a response time (0 to 90%, 100 to 10%) of <7 ms.

Electrical isolation is provided between input, output 1, output 2, and supply, featuring a working voltage of 300 Vac and a test voltage of 2.5 kVac. The signal-to-noise ratio exceeds 60 dB. EMC immunity influence is ≤±0.5% of span under standard conditions and <±1% of span for extended NAMUR NE 21, A Criterion, Burst environments.

Input Specifications

• Current Input: Measurement range up to 0 to 20.5 mA; functional range 0 to 23 mA. Programmable ranges include 0 to 20 mA and 4 to 20 mA.
• Voltage Input: Measurement range up to 0 to 10.25V; functional range includes 0 to 11.5V/ 0 to 5.75V. Programmable ranges include 0 to 5V, 1 to 5V, 0 to 10V, and 2 to 10V.
• Input Resistance: ≥500 kΩ for voltage input; <1.5V drop for current input.

Output Specifications

• Configuration: 2 outputs (splitter function).
• Current Output: Signal range up to 0 to 20.5 mA; programmable ranges include 0 to 20 mA and 4 to 20 mA. Load is limited to 300 Ω max at 23 mA.
• Voltage Output: Signal range up to 0 to 10V; programmable ranges include 0 to 10, 2 to 10, 0 to 5 and 1 to 5V. Load is >10 kΩ min.

Power & Isolation

The unit requires a supply voltage of 16.8 to 31.2 Vdc via power rail or connectors, with maximum power consumption of 1.2 W (internal typical 0.4 W). It provides >17V/20 mA for 2-wire transmitter supply.

Configuration Options

The DRSL-SP2 series features a slimline housing with dimensions of 113 H x 6.1 W x 115 mm D (4.4 x 0.24 x 4.5") and weighs approximately 70 g (0.15 lb). It is designed for DIN rail mounting per standard DIN EN 60715 - 35 mm.

Signal ranges are selectable via DIP switches to match the required output span. The unit utilizes screw terminals compatible with wire sizes from 0.13 x 2.5 mm²/AWG 26 to 12 stranded wire, requiring a torque of 0.5 Nm for connection.

Available accessories include:

• DRSL-PWR-RAIL: Power rail with cover and end covers (1 m length).
• DRSL-PCU: Power connector unit providing 24 Vdc/2.5 A output to the power rail.
• DRSL-MOD-STOP: Module stop for supporting mounted devices on the power rail.

The device carries CE, UL, and RoHS certifications with a 1 YEAR WARRANTY. It is rated IP20 and suitable for Pollution degree 2 and measurement/overvoltage category II installation areas.

Key Product Differences

The primary model in this series is the DRSL-SP2, identified as an isolated signal conditioner/splitter for process signals. The unit supports both current (mA) and voltage (V) input/output configurations through programmable DIP switch settings rather than distinct hardware variants.
