1.0 Device Overview [T-Series Datasheet]
This document contains device-specific information for the following devices:
T4
T4-OEM
T7
T7-Pro
T7-OEM
T7-Pro-OEM
T8
This family introduces a new line of high-quality analog and Ethernet data acquisition hardware combined with the main traditional advantage of all LabJack data acquisition hardware—namely, high performance and rich feature set at a competitive price point. These features make the T-series a logical choice for many high-performance applications where Ethernet, WiFi, and cost are primary considerations.
Core Features
All T-Series Devices
On-board Lua scripting for custom, headless operation
Device Variants
T-Series devices are built in several configurations:
Standard – The standard device configuration. Comes in a red case with screw terminals and DB connectors installed.
OEM – The device PCB without USB, screw-terminals, or the DB connectors installed. Intended for customers that integrate LabJack devices into their own products.
Pro (not available for all devices) – The Pro option adds hardware upgrades such as higher resolution (ADC) and WiFi. This option can be stacked with any of the Standard or OEM configurations.
For more information about the OEM variants, see Section 22: OEM Versions
Family Variants
All T-series Devices
All T-Series devices use Modbus TCP and are compatible with the LJM Library. Programs designed for one T-Series device will often work on other T-Series devices with minimal changes.
T4 vs T7
T4 characteristics that differ from the T7:
12-bit effective resolution on HV and LV lines.
AIN (0-3) are high voltage (±10V).
Flexible I/O lines: The T4 I/O lines FIO (4-7) and EIO (0-3) are software-configurable to be either low voltage analog inputs (0-2.5V) or digital I/O lines (3.3V logic level).
T7 vs T7-Pro
The T7-Pro has all features of the normal T7, with the following added:
Wireless Ethernet 802.11b/g.
24-bit low-speed sigma-delta ADC.
Battery-backed real time clock for stand-alone data logging.
Factory installed microSD card for stand-alone data logging.
Also see the block diagram in the hardware overview section.
T7-OEM and T7-Pro-OEM
There are also OEM versions of the T7 and T7-Pro. The OEM versions are the same in terms of features, but the enclosure and most connectors are not installed on the OEM versions, allowing customization as needed. See 22.0 OEM Versions for details.
T8
The T8 builds upon the success of the T4 and T7 devices and adds unique features previously unavailable to LabJack customers.
8 Isolated Analog Inputs (1000 Vrms channel to channel and channel to ground isolation
Simultaneous sampling for added timing precision
24-bit ΣΔ ADC (up to 40k samples/s/ch) previous LabJack devices with high resolution converters were low speed sampling
10+ different Voltage Ranges: ±11V, ±9.6V, ±4.8V, ±2.4V,±1.2V, ±0.6V, ±0.3V, ±0.15V,±0.75V, ±0.36V, and ±0.18V
