Battery testVoltage, current and temperature
Pack voltage and current on the high speed analogue inputs, with cell temperatures on thermocouples, all on one CAN timeline.
K-BOX · Multi-DAQ module
Temperature, voltage, current and PWM. One module.
K-BOX is the multi-DAQ data acquisition module for the K-Series. Measure thermocouples, software switchable voltage, current and PWM together, then put it all on CAN for any logger, time synchronised with the network data.

One module, every measurement
Four kinds of signal, one module
Thermocouples, software switchable voltage from ±80 V to ±10 V, current via a clamp or shunt, and PWM, all measured together and transmitted on CAN.
Sample rate that follows the channel count
Eight bipolar differential analogue inputs at variable rates: all 8 at 1 kHz, 4 at 2 kHz or 2 at 10 kHz. Trade channels for speed when a transient needs it.
The whole rig, on the CAN timeline
Transmits standard CAN with a supplied DBC file, so any logger decodes it, REBEL, REXGEN or third party. Time synchronised with the vehicle network data.
Thermocouples, compensated
Up to 8 type K, J or T inputs with cold junction compensation. ±1°C accurate, minus 200 to plus 1250 degrees.
Powers the sensors too
Regulated 5 V and 24 V outputs supply external sensors, up to 80 mA combined. Fewer boxes on the rig.
Configured once in K-CAL
Set ranges, rates and CAN IDs over the bus, watch the built in oscilloscope, export a DBC. Settings stored in the module even when unpowered.
Full specifications, including accuracy, isolation, CAN output and configuration, in the spec sheet below.
Under the skin
An instrument first, a module second
Sixteen bit conversion, isolation between every board and settings that survive a power cycle. Measurement you can put in the report.
Isolated and protected from the rig
Galvanic isolation separates the enclosure, power, CAN and the analogue and thermocouple boards, with over voltage protection to ±150 V on the analogue channels. Ground loops and rig faults stay out of the measurement.

Daisy chain in and out connectors link power and CAN through a stack of K-Series modules.
CCP, CAN and sensor data, from one robust and cost-effective system.
We have used several suits of REBEL LT with K-BOX together for several years to obtain CCP, CAN messages and sensor data including pressure and temperature measurements. The whole system is very robust and stable for getting what we need by such a cost-effective system. Now we could hardly take the system off the vehicle as we could not do the vehicle test without it.
Applications
Where K-BOX goes to work
Mixed signal measurement across temperature, voltage, current and PWM.
Battery test
PowertrainMixed signals, one box
Temperatures, pressures on voltage inputs and pump PWM captured together, replacing several single purpose acquisition boxes.
High speed transientTwo channels at 10 kHz
Fast electrical transients on two channels at 10 kHz, protected to ±150 V against the rig.

Frequently asked questions
Common questions
Can K-BOX log data on its own?
No. K-BOX is an instrumentation module: it measures and transmits on CAN. Pair it with any CAN logger, REBEL, REXGEN or third party, or use the K-TC if you want standalone temperature logging.
How do I configure it?
Over the CAN bus in K-CAL, using an Influx logger or a CAN to USB interface such as a Kvaser Leaf, available on request.
Which thermocouple types does it support?
Types K, J and T, cold junction compensated, from –200 °C to +1250 °C.
Can it measure current?
Yes, on the analogue inputs via a current clamp or shunt, within the ±80 V to ±10 V switchable ranges.
Can it power my sensors?
Yes. Regulated 5 V and 24 V outputs supply up to 80 mA combined for external sensors.
Does it work with other manufacturers' loggers?
Yes. K-BOX transmits standard CAN and ships with a DBC file, so any logger or analysis tool decodes it.
