DRG-SC-Series-Sig-Cond

Supported Applications

The Omega DRG-SC Series consists of DIN rail mount signal conditioners designed for high-density installations. These modules accept a wide variety of input signals including thermocouples, RTDs (PT100, PT500, PT1000; Cu10, Cu25, Cu100), strain gage bridges, DC voltages and currents, AC voltages and currents, frequency inputs, and potentiometers. The series is field configurable for input and output ranges to accommodate specific measurement requirements.

Operating Conditions & Performance

All modules provide 1800 Vdc isolation between the input, output, and power supply. ESD susceptibility meets IEC 801-2, level 2 (4 kV). The typical response time is 200 mS (10–90%). Operating ambient temperature ranges from 0 to 55°C (32 to 131°F), with storage temperatures supported between -25 to 70°C (-13 to 158°F).

Humidity ratings are specified as operating: 15 to 95% (@45°C) non-condensing; soak: 90% for 24 hours (@65°C). Accuracy varies by input type and range:

• DC Voltage/Current, RTD: ±0.1% typical, ±0.2% max
• Frequency: ±0.1% of selected range
• Potentiometer: ±0.1% maximum
• <small>< 2 mA/20 mV inputs: ±0.35% fs</small>
• <small>> 2 mA/20 mV inputs: ±0.1% fs</small>
• Thermocouples: Ranges include ±2°C (J, -200 to 750°C), ±5°C (K, -200 to -140°C), ±6°C (R & S, 50 to 1760°C), and ±5°C (B, 500 to 1820°C).

Input Ranges by Type

The series supports extensive input ranges documented in the specification tables:

• Thermocouple: -200 to 750°C (J), -140 to 1250°C (K), -150 to 1000°C (E), -150 to 400°C (T), 50 to 1760°C (R & S), and 500 to 1820°C (B).
• RTD: PT100/PT500/PT1000 ranges from -200 to 600°C; Cu10/Cu25/Cu100 ranges from -200 to 260°C.
• Bridge/Strain Gage: 0.5 mV to 50 mV with excitation of 1 to 10 Vdc.
• DC Voltage/Current: 10 mV to 100 V (Voltage); 1 mA to 100 mA (Current).
• AC Voltage/Current: 100 mV to 200 Vac; 10 mA to 100 mAAC.
• Frequency: 2 Hz to 10,000 Hz (50 mV to 150 Vrms).
• Potentiometer: 100 Ω to 100 KΩ.

Output Signal & Load Resistance

The modules offer five standard output ranges: 0-5 V, 0-10 V, 0-1 mA, 0-20 mA, and 4-20 mA. Voltage outputs have an impedance of <10 Ω with a drive capability of 10 mA max.

Current output compliance limits are:

• 0–1 mA: 7.5 V max (7.5 KΩ)
• 0–20 mA and 4–20 mA: 12 V max (600 Ω)

Note: The DRG-SC-DC-B model provides ±5 V and ±10 V output only.

Power Supply & Mounting

The series operates on a 9–30 Vdc power supply, consuming 1.5 W typical (2.5 W max). The slim housing dimensions are 12.7 mm width x 90.0 mm height x 17.7 mm depth (0.496 in x 3.54 in x 0.697 in), allowing mounting on standard 32 mm or 35 mm DIN rails.

Configuration Options

The DRG-SC Series is available as model-specific input types, each with distinct case styles and capabilities:

• DRG-SC-TC (Case Style B): Thermocouple Input Signal Conditioner.
• DRG-SC-RTD (Case Style B): RTD Input Signal Conditioner.
• DRG-SC-BG (Case Style B): Bridge input signal conditioner for strain gages.
• DRG-SC-DC-U (Case Style A): DC voltage and current with unipolar output ranges.
• DRG-SC-DC-B (Case Style A): DC voltage and current with bipolar output ranges.
• DRG-SC-FR (Case Style A): Frequency Input Signal Conditioner.
• DRG-SC-PT (Case Style A): Potentiometer Input Signal Conditioner.
• DRG-SC-AC (Case Style A): AC Voltage and Current Input Signal Conditioner.

The series includes a 5-year warranty and CE certification. Accessories include the DRN-PS-1000 power supply, RAIL-35-1/RAIL-35-2 DIN rails (1 m or 2 m lengths), and the DRG-C006 shunt resistor.

Key Product Differences

Variants within the series are distinguished by their input signal type, which dictates the model suffix and case style. Models ending in -TC, -RTD, and -BG utilize Case Style B housings, while models for DC (bipolar/unipolar), Frequency (-FR), Potentiometer (-PT), and AC inputs use Case Style A.

Output configuration varies by model: the DRG-SC-DC-B is restricted to bipolar voltage outputs (±5 V, ±10 V) as noted in the specifications. All other models support the standard configurable output ranges of 0–5 V, 0–10 V, 0–1 mA, 0–20 mA, and 4–20 mA.
