Characteristics

The USB connection to the host computer is electrically isolated. This ensures that mutual influencing of the computer and the measurement set-up is prevented effectively.

The outputs of the CEBO LC® are short-circuit-proof. The inputs are protected against over-voltage.

The power is supplied via the USB 2.0 interface.

The built-in temperature sensor enables the determination of the comparison temperature for cold junction compensation (CJC) when connecting thermocouples.

The inner workings of the CEBO LC are encapsulated in a rugged aluminium enclosure with non-slip rubber fittings. The built-in USB connector has a high mating force in order to prevent accidental disconnection of the CEBO LC.

Large 5-mm screw terminals allow easy connection of sensors, actuators and measurement signals.

The CEBOLAB software included free with delivery makes it easy to carry out many measurement tasks. There are application programming interfaces (API) for all popular languages and LabView® examples.

Technical specifications:

Analogue inputs: - 14 single-ended or 7 differential - The inputs can be used in pairs as differential inputs. - Measurement resolution: 16 bit (higher resolution possible by oversampling) - Measurement ranges: ±10 V, ±1 V, ±100 mV, ±10 mV - High-impedance instrument amplifier inputs - Sampling rate: 65 to 85 ksps max. (depending on the number of enabled channels) - Response time (latency): 0.9 ms typ./4 ms max.

Analogue outputs: - 2 independent outputs (OpAmp buffered) - Adjustable voltages: -10 V to +10 V - 12-bit resolution equates to 4096 adjustable increments - Short-circuit-proof outputs

Digital inputs/outputs: - 20 signals - Each signal can be used individually as an input or output - CMOS voltage level (3.3 V nominal) - 5 volt compatible - All digital I/O signals are short-circuit-proof. - Response time (latency): 0.9 ms typ./4 ms max.

Misc.: - Internal digital temperature sensor for cold junction compensation (CJC) when connecting external temperature sensor. - 32-bit counter with dedicated "CNT" input. External trigger "TRG" can be configured as input and output. - Synchronisation of multiple devices through trigger signals (master/slave). - 2 constant current outputs (e.g. for measuring resistance or resistive sensors). Applied current: 10 µA or 200 µA. - Isolated sensor power supply unit: 5 V/100 mA - Recording timing: software-controlled via a built-in, quartz-exact hardware clock through external trigger signals. - Recording operating types: single-value recording; recording of fixed-length data blocks (started by software or external trigger signal); continuous recording (streaming). - Connection to the computer and power supply unit via USB 2.0 (full speed, 12 Mbit/s). - No transfer of noise from the computer to your measurement set-up and no annoying ground loops caused by the electrically isolated USB interface. The ground of the CEBO LC is not connected to the ground of the host computer! - High-performance application programming interfaces (API) optimised for ease of use. - Bundled software: drivers for Windows® (LINUX® and Mac OS X® under development), CEBOLAB® measurement software, API, and code samples (C++, Java, .NET, Python), examples and VI files for LabView®.
