LDX-D DIN Rail Signal Conditioner for AC LVDT Transducers

 Supported Applications

The Omega LDX-D is a DIN rail signal conditioner designed for AC transducer applications, specifically DC-powered conditioning of analog inductive transducers such as LVDTs. The series supports industrial environments requiring adjustable gain and offset configuration for sensor signals.

By linking two LDX-D modules, users can perform specific analog arithmetic functions including A + B, A - B, (A + B)/2, and (A - B)/2.

Operating Conditions & Performance

The LDX-D operates within an ambient temperature range of 0 to 60°C (32 to 140°F) with a storage temperature capability from -20 to 85°C (-4 to 185°F). The device requires a power supply of 10 to 30 Vdc. Supply current varies by output configuration: the voltage range draws 140 mA @ 10 Vdc and 60 mA @ 30 Vdc, while the current range draws 160 mA @ 10 Vdc and 70 mA @ 30 Vdc.

Performance specifications include a linearity of <0.1% FSO and an accuracy class of <0.1% FSO. The temperature coefficient for both gain and offset is specified as <0.01% FSO/°C. A warm-up period of 15 minutes is recommended prior to operation.

Signal Specifications

• Input Range: 55 to 5000 mV with an input load resistance of 100 kΩ.
• Excitation Voltage: 3 Vrms nominal, selectable at 5-, 10- or 13-kHz via internal links.
• Output Options: Up to ±10 Vdc voltage output with <1 mVrms ripple; up to 20 mA current into a 150 Ω load.
• Bandwidth (-3 dB): Link selectable at 500 Hz or 1 kHz.
• Output Offset: Adjustable up to 100% of span.

Configuration Options

The LDX-D series is housed in a green polyamide enclosure designed for standard DIN rail mounting, clipping directly onto a 35 mm top-hat rail (TS35 EN50022). The unit weighs 120 g (4.2 oz) with overall dimensions of 99 mm height (3.9 in), 145 mm width (5.7 in), and 111 mm depth (4.4 in).

Configuration & Connections

• Connections: Transducer, power supply, and output signal connections are made via screw terminals located on the front of the unit.
• Adjustments: Signal polarity, span, and offset are adjustable using internal links and front-panel fine-adjustment potentiometers.

Key Product Differences

The series is represented by a single model number: LDX-D. This unit functions as a DC-powered signal conditioner for AC LVDTs mounted on DIN rail. The device carries CE marking and includes a 1 YEAR WARRANTY.

Safety warnings indicate the equipment should not be operated in an explosive atmosphere or used in safety-critical environments. It is noted that these products are not designed for human applications. Users must observe electrostatic discharge (ESD) precautions during installation, adjustment, or when the case cover is removed.
