Supported Applications
The Omega DMD4059 Series is a field-rangeable, isolated signal conditioner designed for bridge and strain gage sensors. The series accepts inputs from one to four full Wheatstone bridges (100 Ω to 10,000 Ω) or pressure transducers, filtering and amplifying millivolt signals into linear DC voltage or current outputs. Documented applications include load cell weighing systems, strain gage pressure transducer monitoring, and tank level or flow measurement.
Operating Conditions & Performance
The DMD4059 operates within an ambient temperature range of -10°C to +60°C (14°F to 140°F). The module provides full 3-way isolation (input, output, and power) rated at 1200V for ground loop elimination. Accuracy specifications include better than ±0.1% of span linearity and stability better than ±0.02% of span per °C within the ambient temperature range.
Response time is typically 70 milliseconds (14.2 Hz). A DF option provides a typical response time of 10 milliseconds (100 Hz). The unit features an adjustable excitation power supply selectable from 0 to 10 VDC in 1 V increments, with a maximum output capability of 10 VDC at 120 mA. Load resistance is specified up to four 350 Ω bridges at 10 VDC.
Configuration Options
The series supports DIN rail mounting in an enclosure rated IP40 (IP 40). Dimensions are 0.89" W x 4.62" H x 4.81" D (22.5 mm W x 117 mm H x 122 mm D), with a weight of 159 g (5.6 oz). Electrical connections utilize four 4-terminal removable connectors supporting up to 14 AWG wire size.
Configuration options include:
- Power Supply Options: Standard models accept 85-265 VAC, 50/60 Hz or 60-300 VDC. The DMD4059-DC variant accepts 9-30 VDC or 10-32 VAC.
- Output Signals: Configurable DC voltage outputs include 0-1 to 0-10V, ±5V, and ±10V. Current output options range from 0-1 mA to 4-20 mA (Sink or Source).
- Input Ranges: Supports bridge inputs with sensitivities from 0.5 mV/V to 40 mV/V, covering input ranges of 0 to 5 mV through 0 to 400 mV.
- Calibration Options: The M01 option includes a switch with an internal calibration resistor; the M02 option provides a switch for external (load cell) calibration resistors.
The module features field-configurable input, output, excitation, and zero offset settings via rotary switches. A test button is included for diagnostic purposes.
Key Product Differences
The series consists of two primary model configurations distinguished by power supply requirements:
- DMD4059 (Standard): An isolated strain gage signal conditioner powered by 85-265 VAC, 50/60 Hz or 60-300 VDC.
- DMD4059-DC: A low voltage isolated strain gage signal conditioner designed for operation on 9-30 VDC or 10-32 VAC power sources.
Both models share the same physical dimensions, IP40 enclosure rating, and measurement capabilities. The series is RoHS compliant, lead-free, made in the USA, and carries a lifetime warranty.

Is this a single or multi-channel device? We would like to connect 4 load cells with different readings. Will 1 device be able to output each individual reading?
Hello, this is a single channel device, (you may use upto 4 load cells PROVIDED you are using a summing box, that sums the output of all four load cells).
In your case if you need outputs from each load cell, then you will need four separate signal conditioners.

On the DMD4059-DC model, I have one that reads almost the same pressure all the time when extruder is hot. When it is cool, the reading does not drop off. I have plugged new pressure transducer into it and it still does not read zero or anywhere close.

I am facing issue connecting Load cell to DMD4059-DC, whenever I connect load cell its input LED goes off also not getting any output signals. Can anyone help with troubleshooting?
The green input LED provides a visual indication that a signal is being sensed by the input circuitry of the module. It also indicates the input signal strength by changing in intensity as the process changes from minimum to maximum.
If the LED fails to illuminate, or fails to change in intensity as the process changes, check the module power or signal input wiring. Note that it may be difficult to see the LEDs under bright lighting conditions.
The red output LED provides a visual indication that the output signal is functioning. It becomes brighter as the input and the corresponding output change from minimum to maximum.
For current outputs, the red LED will only light if the output loop current path is complete. For either current or voltage outputs, failure to illuminate or a failure to change in intensity as the process changes may indicate a problem with the module power or signal output wiring.
Make sure that you have a jumper wire between 6 and 12. Please see wiring for "No Sense Leads" in the manual.
Make sure the resistance across the red and black wires in the load cell are 350 ohm.
Make sure the resistance across the green and white wires in the load cell are 350 ohm. (approximately)

For the DMD4059 Strain Gauge to DC Signal Amplifier, is this model able to handle a switching power supply? If it's supply voltage type is DC and it's given an alternating current, what would happen?
Both variants of the DMD4059 will run on AC or DC. The DMD4059-DC Low power version will run on 9 to 30 VDC or 10 to 32 VAC. The Standard DMD4059 will run on 80 to 300 VDC or 80 to 265 VAC. They will not work with a switching power supply.

Data sheet says "The DMD4059 accepts an input from 1 to 4 strain bridge sensors" - what is this? It only has 1 output - are the sensors in parallel? Is there a diagram of how to do this? Can it provide excitation to several sensors that use other amps?
Thank you for your question?
The unit will only power up to 4 sensors.
You are correct that the unit will only take one input.
Hope this was helpful.

DOes this device have noise filter? If so what is its cutoff frequency? To what EMI standard is it qualified for?
Thank you for your inquiry, The DMD4059 provides some filtering for stabilizing the signal. For more in-depth information about the filter please contact our Technical Support department @ support@omega.com

I'm trying to read the strain from a single strain gage. Can this device be used for that, or does it only work on a full bridge?
Daniel, The DMD4059 unit will work only with full bridge circuits, if you have a single strain gauge you may complete the bridge using a bridge completion module like the BCM-2-350R (assuming you have a 350 ohm strain gauge)
