LR8102 Datalogger
- modular data logger for recording on up to 3000 channels
- unlike traditional HIOKI loggers, the ability to simultaneously record current (with HIOKI probes) and thus electrical power
- due to the high measurement accuracy, multi-channel analysis of electrical efficiency is possible with this logger (replacement of a power analyzer)
- the LR8102 base unit must be equipped with one or more optional input modules (selection of accessories below)
- for less demanding applications, the more economical LR8101 is available
- 3-year warranty
Parameters and specifications
HIOKI is a completely new series of modular data loggers, developed especially for testing needs in the field of electromobility and renewable energy - but not only there.
The basic LR8102 module, which provides communication with the host system (PC), must be supplemented with at least one measuring unit. If one or more units (but max. 4 units per logger) are used for power measurement (M7103), an M1100 power supply must also be installed in the system. Thanks to the optical synchronisation between the individual LR8102 loggers with the fitted input units, it is possible to build a truly multi-channel system with up to 3000 channels:
| max. number of channels vs. sampling rate | 800 (5 ms), 1500 (10 ms), 3000 (20 ms) |
| max. number of connected input modules | 10 (with a limit of max. 4x M7103) |
| communication interface | 2x LAN, 1x CAN |
| real-time sending of measured values (for HIL simulations) | YES (via LAN2 or CAN interface) |
| possibility of synchronizing multiple loggers | YES, max. 10. via fiber optic cables. |
| Compatible input units | M7100: 15 channels (voltage, temperature); max. 1500 VDC (to ground), fastest sampling time 5 ms |
| M7102: 30 channels (voltage, temperature); max. 600 VDC (to ground), fastest sampling 10 ms | |
| M7103: 3 channels (U+I); max. 1500 VDC (to ground), 500 kHz sampling, range of measured currents according to the type of HIOKI probe connected | |
| M1100: power supply for 1 or more M7103 units |
Applications
Monitoring of entire BEV traction battery packs during charge/discharge test. With multi-channel measurement and the ability to measure high voltages up to 1500 VDC, it is possible to measure up to hundreds of individual battery cells while monitoring the behavior of the battery pack as a whole, including the temperatures of the individual cells. At the same time, the LR8102 also meets the requirements for hardware-in-the-loop simulations thanks to its high communication speed with the host PC:
Multi-channel testing of string inverters - the LR8102 datalogger offers the possibility of simultaneous measurements on up to 120 power channels simultaneously. The graphic below shows an example of a 36-channel connection:
