15-Channel Logger Module for Voltage, Temperature and Resistance, 10 ms

Key Features

• 15 input channels for DC voltage, temperature, humidity and resistance
• Supports thermocouples and RTDs
• 10 ms update interval
• A/D resolution: 16 bits
• Voltage: 9 ranges, from ±10 mV to ±100 V and for 4-20 mA signals 

The U8551 Universal Module is a 15-channel plug-in module for the LR8450 Data Logger Series. Up to four U8551 modules can be connected to a single LR8450 or LR8450-01 Data Logger, allowing users to record data from up to 60 channels in a single device.

This module supports precise DC voltage measurements with a direct input capacity of up to 100 V. Input signals are connected to the module through a spring-cage terminal block, providing a quick and secure, vibration-resistant connection. Its 300 V isolation to earth and between channels ensures safe and reliable operation.

Additionally, the U8551 can perform resistance measurements. Four-wire measurements are available in four selectable measurement ranges (10 Ω, 20 Ω, 100 Ω, and 200 Ω) with an accuracy of 0.1%, ensuring high-precision results for various applications.

The U8551 can also measure temperature using thermocouples or RTDs (resistance temperature detectors) of the types Pt100, Pt1000, and JPt100. Supported thermocouple types include K, J, E, T, N, R, S, B, and C. The module can also capture humidity, making it ideal for versatile applications from environmental monitoring to the evaluation of material properties.

Its compatibility with various thermocouple and RTD types allows flexibility for diverse thermal analysis tasks in research, industrial, and environmental settings. Each channel can be configured individually, giving users the freedom to tailor the setups to their specific testing requirements.

With a fast update interval of 10 ms and 16-bit A/D resolution, the U8551 delivers high-precision data acquisition. The module offers nine measurement ranges, from ±10 mV to ±100 V, ensuring accurate readings across a variety of applications. To measure 4-20 mA signals, a 250 ? shunt resistor can be used with the 1-5 V range, adding to the module's adaptability.
