Supported Applications
The Omega DRC-4710/4720 series comprises DIN Rail Mount Bridge Input Signal Conditioners designed for bridge input applications, specifically load cells and strain gages. These self-contained DC-powered modules also support voltage input configurations. The units feature a precision instrumentation amplifier with filtered output to condition signals from these sensing elements.
Operating Conditions & Performance
The series operates within an ambient temperature range of 0 to 55°C (32 to 131°F) and supports storage temperatures from -40 to 80°C (-40 to 176°F). Input ranges are dip switch selectable at 0 to 10 mV, 0 to 20 mV, or 0 to 30 mV. The modules provide a linearity of ±0.01% and an input offset voltage of ±70 μV with a temperature coefficient of 0.7 μV/°C.
Performance specifications include a common mode rejection (DC) of 100 dB, an input noise typical value of 0.3 μV pp (0.1 to 10 Hz), and a frequency response of DC to 10 Hz Total RMS via a 2-pole filter. The built-in bridge excitation supply provides a fixed output of 10V ±1.0% with a maximum load current of 30 mA.
Configuration Options
The series is available in two primary models distinguished by their output signal types:
- DRC-4710: Provides a 0 to 10 Vdc output with a maximum load current of 5 mA.
- DRC-4720: Provides a 4 to 20 mA output. This model supports a loop resistance up to 250 Ω max and has a compliance voltage limit of 5.5V max.
All models utilize screw terminal blocks for electrical connections and include external zero (up to 20% max output) and span adjustment potentiometers. The physical dimensions are 96 H x 27 W x 42 mm D (3.78 x 1.06 x 1.65") with a weight of 85 g (3 oz).
Power requirements for the series are 18 to 26 Vdc. Input current consumption varies by model and bridge load: 40 mA for DRC-4710 or 55 mA for DRC-4720 when driving one 350 Ω Bridge.
Key Product Differences
The primary distinction between the two models is the output signal format. The DRC-4710 outputs a voltage signal (0 to 10 Vdc), while the DRC-4720 outputs a current loop signal (4 to 20 mA). Both share identical input ranges, excitation supply specifications, and physical housing dimensions.
Optional accessories include the IDRN-PS-1000 switching power supply (95 to 240 Vac Input, 24 Vdc output @ 850 mA) and DIN rail mounting hardware in two lengths: RAIL-35-1 (1 m / 3.3') or RAIL-35-2 (2 m / 6.6').
