The DNA-TC-378, DNR-TC-378 and DNF-TC-378 are fully isolated, high-precision, 8-channel thermocouple simulator board compatible withUEI’s popular “Cube”, RACKtangle and FLATRACK I/O chassis respectively.The boards offer full 16-bit resolution and guarantee monotonicity overthe entire operating temperature range. Each DNA/DNR-TC-378 channelprovides an output range of ±100 mV which encompasses the outputranges of all common thermocouples. Each output is capable of driving±10 mA though it’s unlikely a TC input would require such high current.
The DNx-TC-378 provides extensive built-in-test diagnostics. An on-board A/D converter on each channel allows the user to monitor outputvoltage and current as well as board temperature. A solid state relay oneach output allows the D/A channel to be disconnected from the field I/Oso an open thermocouple can be simulated and the input systems openTC detection circuitry can be tested. A 1024 sample FIFO allows each D/Ato be updated at 1 kHz per channel (8 kHz aggregate) without data loss.
The board provides three cold-junction input channels to measuretemperature where the TC-378 is connected to the applicationsthermocouple input device. This cold-junction temperature can beutilized by the application software to compensate for error caused bythe lack of actual cold-junction error (as there will not be the extraneousdissimilar metal connection that causes the whole CJC issue). The threecold-junction channels are fully electrically isolated from the TC channels,but not from each other.
Connections to the DNx-TC-378 are through a female DB37 connector.OEMs will find it easy to find mating connectors for custom cables,while end-users may take advantage of UEI’s DNA-STP-378 screwterminal panel. In addition to the screw terminals, the DNA-STP-378also includes 3 cold junction sensors. Connections to the DNA-STP-378are made via the DNA-CBL-37 or DNA-CBL-37S series cables.
The DNx-TC-378 series includes software drivers supporting allpopular operating systems including: Windows, Linux, QNX,VXWorks, and most other popular Real-Time Operating Systems.Windows users may take advantage of the powerful UEIDAQFramework which provides a simple and complete software interfaceto all popular Windows programming language and data acquisitionand control applications (e.g. LabVIEW, MATLAB).
In this UEI Master Class, we provide insights on the analog output options you can find it our hardware including:
• The role of operating modes in certain applications
• Different generic AO variants in UEI’s product line
• Configuring UEI’s specialized wave function generator for your signaling application
UEI's Guardian Series brings system monitoring to a whole new level.
In this Master Class, UEI application engineer Austyn Turner walks through our sophisticated and reliable on-board monitoring diagnostics we call “Guardian”, also known as "Built-In-Test" or BIT.
