Supported Applications
The Omega DRST-BG is a microprocessor-controlled, front-programmable mV transmitter designed for load cell applications. It converts bipolar millivolt signals from transducers into standard current or voltage outputs suitable for data acquisition and control systems.
Documented application areas include:
- Tank filling and draining
- Weighing operations
- Cable tensile force measurement
- Level control
Operating Conditions & Performance
The DRST-BG accepts a bipolar input range of -40...100 mV from transducers. The unit provides 17-bit signal dynamics on the input and 16-bit resolution on the output, with an updating time of 20 ms. Response time is programmable between 0.06 s and 999 s.
Performance specifications include a linearity error of ≤ ±0.1% of span and a temperature coefficient of < ±0.01% of span / °C (calibrated at 20...28°C). The effect of supply voltage change is specified as < ±0.002% of span / %V, with an EMC immunity influence of < ±0.5% of span.
Operating conditions require a power supply of 19.2...28.8 VDC and an ambient temperature range of -20°C to +60°C. The unit operates in relative air humidity up to < 95% RH (non-condensing). Internal consumption is rated at 2.2 W, with a maximum consumption of 7.2 W.
Configuration Options
The DRST-BG series supports configurable output signals and excitation voltages via front programming. Key capabilities include:
- Output Signals: Selectable between 0...20 mA or 0...10 V.
- Excitation Voltage: Front-programmable range of 5...13 VDC for transducer supply, with a maximum load capacity of 230 mA.
- Calibration Features: Supports relative calibration and taring via digital input or front key to set 0% and 100% scale without requiring equivalent physical loads.
The unit features an IP50 protection degree and utilizes a standard DIN rail form factor with overall dimensions of 80.5 x 35.5 x 84.5 mm (HxWxD). Electrical connection is provided via an 11-pin terminal block.
Key Product Differences
The series is identified by the model number guide DRST-BG and carries CE and EAC approvals. The single enumerated variant, SKU DRST-BG, represents the standard configuration for this DIN rail signal conditioner family as described in the user manual.
