Supported Applications
The Omega DMD-470 Series consists of AC-powered signal conditioning modules designed for bridge-type sensors, strain gages, and load cells. These isolated amplifiers provide triple-isolated voltage or current outputs to interface with data acquisition systems.
Operating Conditions & Performance
The series accepts input ranges from 5 to 50 mV for a full-scale output of either 0 to 10 Vdc or 4 to 20 mA. Excitation is provided as fixed 10V or variable 5 to 10 Vdc via 6-Wire Bridge Connections. The response time (10 to 90%) is specified at 35 ms.
Operating ambient temperature ranges from -25 to 55°C (-13 to 131°F), with a storage temperature range of -25 to 85°C (-13 to 185°F). Electrical isolation ratings include 1100 Vrms (60 pF) for AC output and 700 Vdc (60 pF) from input to output.
Configuration Options
The DMD-470 Series offers configurable power supplies, output types, and accessories. Both models feature dual zero/tare functions; the tare function allows up to 68% of the input to be offset while maintaining full output span.
Power Supply Options
- 115 Vac ±10 Vac (standard)
- 220 Vac ±10% 50/60 Hz (optional)
- DC powered variants available for specific models
Output Signal Types
- DMD-475: Isolated voltage output, 0 to 10 Vdc
- DMD-476: Isolated current outputs, including 4 to 20 mA and 0 to 20 mA
Accessories
- POWER CORD-SE: Power cord with stripped end termination
Key Product Differences
The series distinguishes between voltage and current output models. The DMD-475 provides a 0 to 10 Vdc voltage output, while the DMD-476 is configured for isolated current outputs (4 to 20 mA or 0 to 20 mA). Model numbers indicate power supply configuration: standard units operate on 120 Vac, with suffixes such as "-220V" denoting 220 Vac operation and "-DC" indicating DC-powered versions. Physical dimensions for the enclosure are 96 L x 51 W x 73 mm H (3.75 x 2 x 2.87") with a weight of 510 g (18 oz).

Does this allow you to either calibrate and/or shunt the gauge and can you use them in 1/4 and 1/2 bridge mode?
You can use a shunt cal resistor to calibrate this unit. It's is designed for a full bridge input. You would have to complete the bridge externally.
