The voltage and thermocouple data acquisition module OM-USB-TC, OM-USB-TC-AI and OM-USB-5201 are USB 2.0 full-speed modules (fully compatible with both USB 1.1 and USB 2.0 ports). These are stand-alone plug-andplay modules which draw power from the USB cable (included). No external power supply is required (except for OM-USB-5201 which requires an ac adaptor). All configurable options are software programmable, and the modules are fully software calibrated.

The OM-USB-TC and OM-USB-5201 provide eight differential thermocouple input channels and have two integrated cold junction compensation (CJC) sensors for thermocouple measurements. The OM-USB-TC-AI provides eight analog input channels that are configured as four differential temperature inputs and four differential or single-ended voltage inputs. The module has one cold junction compensation (CJC) sensors for the thermocouple measurements. Thermocouples inputs are software programmable for types J, K, T, E, R, S, B and N. An open thermocouple detection feature lets you detect a broken thermocouple. An on-board microprocessor automatically linearizes the thermocouple measurement data. Voltage inputs (OM-USB-TC-AI only) are software programmable for ±10V, ±5V, ±2.5V and ±1.25V ranges. Eight independent, TTL-compatible digital I/O channels are provided to monitor TTL-level inputs, communicate with external devices and to generate alarms. The digital I/O channels are software programmable for input or output.

The OM-USB-5201 features eight independent temperature alarms. Each alarm controls an associated digital I/O channel as an alarm output. The input to each alarm is any one of the temperature input channels. The output of each alarm is software configurable as active high or low. The temperature threshold condition to activate each alarm is user programmable. When an alarm is activated, the associated digital I/O channel is driven to the output state. The OM-USB-5201 also has data logging capability. Measurements can be logged to a standard CompactFlash memory card (a 512 MB CompactFlash memory card is included with the OM-USB-5201). Data logging can only be done when the OM-USB-5201 is disconnected from the computer. External power is required for data logging via the included ac adaptor. User programmable settings in data logging mode include sampling interval and logging start mode (on power up, on button press or at a specified data and time).

The OM-USB-TC, OM-USB-TC-AI and OM-USB-5201 modules ship with an impressive array of software, including the new TracerDAQ®, a full-featured, out-of-the-box data logging, viewing, and analysis application; Universal LibraryTM; ULx for NI LabVIEW (comprehensive library of VIs and example programs compatible with LabVIEW v.8.2.1 and later); and InstaCalTM installation, calibration, and test utility-powerful software solutions for programmers and nonprogrammers alike. These modules operate under Microsoft Windows 2000/XP/Vista (32-bit or 64-bit/7 (32-bit or 64-bit) operating systems.The OM-USB-TC, OM-USB-TC-AI and OM-USB-5201 data acquisition modules are 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. A comparison of some of the features included in TracerDAQ vs TracerDAQ PRO is shown below.
