Supported Applications

The Omega OM-CP-VOLT101A Series, part of the NOMAD® Family, provides a low-cost solution for adding recording capability to existing measurement systems. These voltage data loggers are designed for measuring battery voltages, sensor outputs, photovoltaic studies, and other low-level DC sources.

Operating Conditions & Performance

The series features high accuracy with 16-bit resolution and programmable engineering units for low-level DC voltage recording. Operating ambient temperature ranges from -40 to 80°C (-40 to 176°F) in environments up to 0 to 95% RH non-condensing. The enclosure is rated NEMA 4 (IP65). Response time is specified at 133 mS.

Performance specifications vary by input range as documented:

±160 mV Range: Resolution of 5 µV with calibrated accuracy of ±0.01% and differential input type.
-3 to 3 Vdc Range: Resolution of 0.1 mV with calibrated accuracy of ±0.05% and single-ended input type.
-8 to 24 Vdc Range: Resolution of 0.5 mV with calibrated accuracy of ±0.05% and single-ended input type.
-8 to 32 Vdc Range: Resolution of 1.0 mV with calibrated accuracy of ±0.05% and single-ended input type.

Input impedance is >1 MΩ for the ±160 mV model and 125 kΩ for the -3 to 3 Vdc, -8 to 24 Vdc, and -8 to 32 Vdc models. Overload protection ratings are ±5V (for 10 seconds) on the ±160 mV range and ±50V indefinitely on the other ranges.

Configuration Options

The OM-CP-VOLT101A Series is available in four primary input configurations. The housing material is ABS Plastic, with overall dimensions of 36 H x 64 W x 16 mm D (1.4 x 2.5 x 0.6"). Weight is 24 g (0.9 oz). Electrical connections utilize a removable screw terminal.

Power is supplied by an included, user-replaceable 3.6V lithium battery. Data recording and analysis require the OM-CP-IFC200 Windows software and USB interface cable, which are sold separately or as part of specific accessory bundles. The series supports optional NIST calibration certificates.

Available options and accessories include:

OM-CP-BAT105: Replacement 3.6V lithium battery
OM-CP-WATERBOX101A: Weatherproof NEMA 4 (IP65) enclosure for the data logger
Replacement Terminal Blocks: OM-CP-CONNECTOR-2 (2 position, compatible with -3 to 3 Vdc, -8 to 24 Vdc, and -8 to 32 Vdc models) and OM-CP-CONNECTOR-3 (3 position, for the ±160 mV model)

Key Product Differences

Variants within the series are distinguished by their voltage input range, resolution, accuracy class, and input type. Models ending in "-CERT" include a NIST calibration certificate.
