LE5000 Series Intelligent Recorders

LE5000 series are 250mm hybrid recorders with multi-range input. Innovative design high performance recorder provides high accuracy, ±0.05%; high speed scanning, 0.1second for 36 points and high speed recording, 1 line in 3 seconds. Simple operational keys and PC setting functions drastically improved usability of recording system.

High speed scanning at 36 points/sec and high-speed recording
Rapid changes of process data such as lab test results can be scanned simultaneously at 36 points/sec and recorded at about 1 line/ 3 sec. Data for each channel is displayed in 10 different colors which is user selectable.

High accuracy of 0.05%
The accuracy is ±0.05% and the resolution is 1μV or 0.1°C

Various industrial values can be measured at the same time with selectable ranges
With 35 thermocouple ranges and 8 DC voltage ranges, a total of 43 input ranges are provided which enables universal input and optional mixed input: current inputs are also possible.

Superior ease of operation
Operation keys are functionally designed for ease of use.

Engineering port is provided (USB)
A personal computer can be used as an engineering tool and parameter setting and data collecting is available.

Anti-noise countermeasures
High effective anti-noise countermeasures are taken; suppressive induced noise by 130 dB or more in the common mode while 50dB or more is achieved in the series mode. Effective countermeasures are taken against impulse noise.

Communication interfaces are available (Option)
RS-422A, RS-485 and Ethernet can be provided to meet various customers' needs.

Recording and calculation of data communication input (Option)
Data input by communications from a host can be recorded as analog and digital values at the same time with measuring data. Mathematical process of the data communications input from a host can be processed in parallel.
