Detailed Product Overview

The versatile, modular data logger LR8101 can be used in combination with a variety of modules. It is therefore the perfect solution for integration in applications requiring multiple channels and recording intervals as short as 5 ms. The logger can be installed in a 19” rack with an optional rack-mount kit. The LR8101 can be controlled via Gennect One or the freeof-charge Logger Utility software. Additionally, the logger provides several inputs and outputs for alarms, triggers and pulse signals. The enhanced noise resistance ensures accurate and reliable measurements. All available modules can be combined in one system setup, with the main two measurement objectives being power logging and voltage/temperature logging. 

Voltage & Temperature logging with the LR8101

The LR8101 Data Logger can be combined with up to ten M7100 or M7102 modules. The system provides utmost flexibility as it offers the possibility to choose the type and number of modules to exactly fit the test requirements.

In combination with the module M7100 the logger can capture up to 150 channels at 5 ms update interval. With an isolation to Earth of 1500 VDC, CAT II measurements of voltages and temperatures of 800 V and even 1200 V batteries can be performed safely. 

When combined with module M7102 the logger offers up to 300 channels at 10 ms update interval. With an isolation of 600 VDC, CAT II it is the perfect solution for data logging of 400 V batteries. Besides voltage, both modules offer the possibility to capture temperature signals using thermocouples. 

Power logging with the LR8101

When adding the M1100 AC power supply module, up to four M7103 Power Measurement Modules can be connected offering a total of 12 channels for long-term high-precision logging of power. Alternatively, the M7103 can be used to measure voltages and currents. The voltage input channels offer direct measurement of voltages of up to 2000 VDC, 1000 VAC. Long-term current logging is possible with any of the high-precision HIOKI current sensors with an ME15W connector. The sensors are powered by the logger and do not require an external power supply.
