Supported Applications

The Omega OM-DAQXL Series consists of 8 or 16 channel universal input touch screen data loggers designed for standalone operation. These units support a wide range of measurement types including thermocouples, RTDs, thermistors, strain gauges, DC voltage, DC current, and frequency/pulse inputs. The series features IoT/cloud connectivity via OPC UA/DA and MQTT protocols on models equipped with Ethernet or Wi-Fi capabilities.

Operating Conditions & Performance

The OM-DAQXL Series operates within an ambient temperature range of 0 to 50°C (32 to 122°F) at 0 to 95% RH non-condensing. Measurement accuracy varies by input type and range:

Thermocouples: J, K, T, E types offer ±(0.15% of range + 1.7°C) at positive ranges (above -49°C) and ±(0.25% of range + 2.6°C) at negative ranges (-50°C to -200°C). N, R, S, B, C types offer ±(0.15% of range + 2.0°C) at positive ranges and ±(0.25% of range + 2.6°C) at negative ranges.
Thermistors: Accuracy is specified as ±1°C for both 225Ω/10 KΩ (-30 to 150°C) and 10 KΩ (-5 to 150°C) types, with a resolution of 0.1°C.
RTDs: Pt 100, Pt 500, and Pt 1000 sensors (0.00385 curve: -200 to 850°C; 0.00392 curve: -200 to 660°C) provide ±(0.25% of reading + 1°C) accuracy with 0.1°C resolution.
DC Voltage: Ranges from 50 mV (-50 to 50 mV) up to 50V (-30.00 to 30.00V). Accuracy is ±0.1% of FS for ranges up to 20V, and ±0.1V for the 50V range.
DC Current: The 20 mA range (-20 to 20 mA) offers ±0.1% of FS accuracy.
Frequency/Pulse: Inputs support 0 to 250 KHz with an accuracy of ±2 Hz.

The series provides 24-bit analog input resolution and supports sampling rates up to 125 samples/sec per channel. Maximum logging rates depend on the number of active channels: 1 Channel at 125 s/sec, 2 Channels at 50 s/sec, 4 Channels at 25 s/sec, 8 Channels at 10 s/sec, and 16 Channels at 5 s/sec.

Power & Storage

The unit is powered by a rechargeable lithium-ion battery (7.2V @ 4.8 Ah) providing 4 to 8 hours of operation based on display settings, or via an AC adaptor (12 Vdc @ 5A). Data storage includes 1 GB internal memory, with expansion options for up to 32 GB SD cards and 32 GB USB drives.

Configuration Options

The OM-DAQXL Series is configurable across channel count, connectivity, and regional power requirements. The series supports the following capabilities:

Analog Inputs: Supports 8 or 16 channels of universal inputs including Thermocouple (J, K, T, E, R, S, B, C, N), RTD (Pt 100/500/1000), Thermistor, Strain Gauge (100Ω and 350 Ω full bridge with 5V or 10V excitation), DC Voltage, DC Current, and Frequency/Pulse.
Digital I/O: Includes 4 Schmitt trigger-based digital inputs (0 to 24 Vdc single-ended) and 4 open collector digital outputs (5V @ 50 mA).
Alarms & Triggers: Features 4 alarm outputs (open collector, 30V @ 500 mA). Each channel supports two alarms with types including High, Low, Windows In, Windows Out, and Open Sensor. Logging can be triggered by timer, date/time, weekday/time, alarm output, or external trigger.
Connectivity: Standard models include USB Device (PC Communication) and USB Host ports (-EW models add Ethernet 10/100 Base-T TCP/IP). Wi-Fi connectivity is available via a certified USB Wi-Fi Dongle (802.11 b/g/n, up to 150 Mbps) on -EW models.
Physical Configuration: The enclosure includes a protective rubber boot and supports benchtop operation with a tilt stand or wall mounting using the provided keyhole mount. Dimensions are 28.6 L x 15.24 H x 6.35 cm D (9 x 6 x 2.5").
Math Channels: Supports up to 8 or 16 virtual math channels depending on the model configuration.
