Supported Applications
The Omega OM-NET-1608 is an 8-channel multifunction Ethernet data acquisition module designed for high-speed measurement and control tasks. It operates as a networked I/O device requiring a TCP/IP (IPv4 only) or UDP connection to a computer or network, rather than functioning as a stand-alone data logger. The series supports applications involving analog voltage monitoring, signal generation via function generators, digital logic interfacing, and event counting.
Key functional capabilities include:
- Analog input acquisition for DC voltages
- Analog output signaling for control or simulation
- Digital I/O configuration for TTL/CMOS compatible signals
- Pulse counting via a 32-bit counter channel
The device is supplied with TracerDAQ® software, which enables data acquisition and display on Windows® VISTA/7/8/10 (32- and 64-Bit) operating systems.
Operating Conditions & Performance
The OM-NET-1608 delivers high-resolution performance with a 16-bit resolution for both analog input and output channels. The aggregate sample rate reaches up to 250 kS/s across the eight analog input channels, which can be configured as four differential (DIFF) or eight single-ended (SE) inputs.
Performance specifications include:
- Analog Input Accuracy: ±18.7 LSB; DC voltage measurement accuracy components vary by range with gain error at 0.024% of reading and offset errors ranging from 915 μV (±10 V) to 245 μV (±1 V).
- Analog Output Accuracy: ±0.05% of reading ± 1 LSB.
- Settling Time: Typical settling time is 100 μs for both analog input and output channels; specific accuracy at shorter intervals (4, 6, or 10 μS) varies by range as documented in the specification tables.
- Noise Performance: Input noise performance ranges from 0.91 LSBrms to 1.36 LSBrms depending on the selected input voltage range.
The module operates within an ambient temperature of 0 to 55°C (32 to 131°F) and a humidity rating of 0 to 90% RH non-condensing max. Storage conditions are specified as -40 to 85°C (-40 to 185°F). The device is powered by a 5 VDC supply via an included AC adapter, with typical power consumption at 1.5 W.
Configuration Options
The series offers configurable I/O channels and signal ranges tailored for diverse instrumentation needs:
- Analog Input Channels: Four differential or eight single-ended inputs with selectable input ranges of ±10 V, ±5 V, ±2.5 V, ±1.25 V, ±0.625 V, and ±0.3125 V (per manual) or ±10V, ±5V, ±2V, ±1V (per data sheet). Input impedance is 10 MΩ with typical common-mode rejection of 100 dB.
- Analog Output Channels: Two channels supporting output ranges of 0–10 VDC, ±10 VDC, 0–5 VDC, ±5 VDC, and 4–20 mA. Output impedance is 100 Ω.
- Digital I/O: Eight individually configurable TTL/CMOS compatible channels with input/output voltage levels of 0–5 V. Input current is 10 μA; output current is 20 mA.
- Counter Channel: One 32-bit counter for counting TTL pulses up to a maximum frequency of 100 kHz.
The module features a built-in RJ-45, 8-position connector with 10/100 BASE-T auto-negotiation Ethernet port. Field wiring connections are made via screw terminals. The enclosure is constructed from blue plastic housing (per manual) or standard industrial materials, with dimensions of 117.9 L × 82.8 W × 29.0 mm H (4.64 × 3.26 × 1.14") and a weight of approximately 0.4 kg (0.88 lb).
Key Product Differences
The OM-NET-1608 series is available with specific accessories to support installation and power requirements:
- DIN Rail Mounting Kit: Model OM-NET-DINRAILKIT provides DIN rail mounting capability.
