Descrizione

The OM-NET-TC thermocouple input data acquisition module offers high-accuracy temperature measurement with an Ethernet interface. The device offers the best value per channel and the best possible accuracy because the accuracy of the internal measurement electronics exceeds the accuracy specifications of the thermocouple sensors. The OM-NET-TC is functionally equivalent to an OMEGATM OM-USB-TC module (USB interface to computer) which makes application migration very easy.

Ethernet Interface The OM-NET-TC has a built-in highspeed communication port. Users can remotely access and configure the device with software over the Internet.

Thermocouple Input Connect up to eight differential thermocouple (TC) input channels to the OM-NET-TC. The OM-NET-TC supports a maximum sample rate of 4 S/s per channel, and thermocouple types J, K, T, E, R, S, B and N. Thermocouple types are softwareselectable per channel.

Cold-Junction Compensation The OM-NET-TC has two high-resolution cold-junction compensation (CJC) sensors (one per four thermocouple inputs).

Open-Thermocouple Detection The OM-NET-TC is equipped with open-thermocouple detection (OTD) for all thermocouple input channels. With OTD enabled, users can monitor for broken or disconnected thermocouple inputs.

Digital I/O The OM-NET-TC has eight digital I/O channels that are electrically isolated from the analog circuits. Each bit is individually configurable for input or output. Data can be transferred at rates up to 5 kS/s when the device and host are connected by Ethernet to the same local network. Typical throughput is system-dependent. All DIO channels are pulled high by default to 5V through 47 kO resistors with a jumper on the circuit board. Each jumper configures the digital port for pull-up or pull-down.

Temperature Alarms Each digital output can be optionally configured as an alarm for each thermocouple input. When an alarm is enabled, the output line associated with the alarm is driven to the appropriate state determined by the alarm options and input temperature. Use the alarm outputs to control a device or application that indicates when a temperature threshold has been exceeded, or to indicate an open thermocouple condition.

Counter Input The 32-bit event counter pin counts TTL pulses, and accepts frequency inputs up to 10 MHz.

Power The OM-NET-TC requires external power from the 5V, 1A power adapter (OM-NET-PS) included with the device.

Calibration The OM-NET-TC is factorycalibrated using a NIST-traceable calibration process. Specifications are guaranteed for one year. For calibration beyond one year, Contact Omega and return the device for recalibration.

Software The OMB-NET-TC module ships with an impressive array of software, including the new TracerDAQ®, a full-featured, out-ofthe- box data logging, viewing, and analysis application. Driver support and detailed example programs are included for Universal Library programming libraries for Microsoft® Visual Studio® programming languages, and other languages, including DASYLab®, and ULx for NI LabVIEW® (comprehensive library of VIs and example programs compatible with 32- bit and 64-bit LabVIEW 2010 or later) and InstaCalTM installation, calibration and test utility-powerful solutions for programmers and nonprogrammers alike. These modules operate under Microsoft Windows® VISTA/7/8/10 (32-bit and 64-bit) operating systems. The OMB-NET-TC data acquisition module is supplied with TracerDAQ software which is a collection of four virtual instrument applications used to graphically display and store input data and generate output signals:
    • Strip Chart—Log and graph values acquire from analog inputs, digital inputs, temperature inputs and counter inputs
    • Oscilloscope—Display values acquired from analog inputs
    • Function Generator—Generate waveforms for analog outputs
    • Rate Generator—Generate waveforms for counter outputs TracerDAQ PRO is an enhanced version of TracerDAQ and is available as a purchased upgrade (SWD-TRACERDAQ-PRO). A comparison of some of the features included in TracerDAQ vs TracerDAQ Pro (see Spec page PDF).
