Hioki LR8532 Wireless Voltage/Temperature Module

The Hioki LR8532 is a 30-channel wireless measurement module for DC voltage and temperature measurements with the LR8450-01 Data Logger. Each channel can be individually configured for voltage measurement or temperature measurement using thermocouples.

Up to seven LR8532 modules can be connected wirelessly to a single LR8450-01, providing a total of 210 channels. When combined with four U8552 modules, the system can be expanded to a total of 330 channels.

The module features 16-bit A/D resolution and an update interval as short as 10 ms when using up to 15 channels. When more than 15 channels are active, the shortest update interval is 20 ms. Voltage measurements are supported across nine ranges from ±10 mV to ±100 V.

The LR8532 features spring-cage terminals for secure signal connections and 300 V isolation between channels and to earth. Wireless communication allows the module to be positioned close to measurement points, including confined or hard-to-reach locations. The module can be powered by an AC adapter or an optional battery pack.
