Description

The OM-WLS-TC is a wireless USB 2.0 full-speed thermocouple input module (fully compatible with both USB 1.1 and 2.0). The OM-WLS-TC provides 8 differential thermocouple input channels. 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-WLS-TC supports Types J, K, T, E, N, R, S and B thermocouples. Two integrated cold junction compensation (CJC) sensors are included for thermocouple measurements. An open thermocouple detection feature allows detection of a broken thermocouple. An onboard microprocessor automatically linearizes the measurement data. The OM-WLS-TC features 8 independent temperature alarms. Each alarm controls an associated digital I/O channel as an alarm output. The input to each alarm is one of the temperature channels. The output of each alarm is software configurable as active high or low. The temperature threshold conditions to activate each alarm are software programmable. When an alarm is activated, the associated digital output channel is driven to the output state. All configurable options are software programmable. The OM-WLS-TC is fully software-calibrated.

The OM-WLS-TC can be operated as a standalone plug-and-play device which draws power through the USB cable. The unit can also be operated as a remote device that communicates with the computer through the OM-WLS-IFC USB-towireless interface device. An external power supply is shipped with the device to provide power during remote operation. When operating as a remote device, the OM-WLS-TC communicates with the computer through the OM-WLS-IFC device connected to the computer’s USB port. Before the OM-WLS-TC can be operated remotely, it needs to be connected to the computer’s USB port and the network parameters configured to establish a wireless link with the interface device.

Only devices with the same parameter settings can communicate with each other. All configurable options are software programmable using the included InstaCal™ utility software. LEDs on the OM-WLS-TC indicate the status of communications over the wireless link. A LED bar graph shows the fade margin of signals received by the OM-WLS-TC.

The OM-WLS-TC 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. 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 v8.5 through 2012) and InstaCalTM installation, calibration and test utility-powerful solutions for programmers and nonprogrammers alike. These modules operate under Microsoft Windows® XP (32-bit only) and VISTA/7/8 (32-bit and 64-bit) operating systems.
