Three types of input system enable to measure various phenomena

Input system 1 : Multifunction analog input ports

Contains a highly isolated input system which ensures that signals are not corrupted
by noise from other channels. The GL840's inputs are suitable for combined
measurements from voltage, temperature, humidity, logic, and pulse signals.
The standard configuration has 20 analog input channels. It is expandable to
200 channels by adding optional 20 channels extension terminal base unit (B-566)
and input terminal units (B-564 or B-565).

Withstand voltage & Accuracy Multi-input type (B-564) Withstand-voltage type (B-565)
Voltage Input voltage range 20 mV to 100 V 20 mV to 100 V
Max. voltage (Input - GND) 60 Vp-p 300 Vp-p
Temp. Thermocouple R, S, B, K, E, T, J, N, W (WRe5-26)
RTD (Resistance Temp. Detector) Pt100 (IEC751), Pt1000 (IEC751), JPt100 (JIS)
Accuracy Voltage ± 0.1% of F.S. ± (0.05% of FS + 10μV)
Temperature* ± 1.55 ºC ± 1.1 ºC

* Accuracy rating for K-type thermocouple at 100˚C includes reference junction compensation.
Accuracy varies by temperature levels and thermocouple types.

The following shows how a standard configuration is expanded to
more than 40 channels

Offers longer cable for the input terminals

Input terminal blocks can be connected directly (in daisy chain), or using the B-565 cable(s).
This allows the input terminals to be placed in separate locations according to the
need of the application. The input terminal unit and the GL840 main body can be
extended by using an extended connections cable.

*If the signal is affected by noise, it may be required to use a slower sampling.

Input system 2 : Support digital sensors

Digital sensors and input terminal/adapters for the GL100
connects to the GL840 directly


Input system 3 : 4 channels of Logic/Pulse inputs

Supports 4-channels logic or pulse signal inputs. Pulse mode allows cumulative, instant,

or rotational values for industrial measurement capability with speed and flow.



 

Maximum sampling interval of up to 10ms

Provides faster sampling rates for voltage measurements. Up to 10ms sampling speed
is achievable when limiting the number of channels in use.

Built-in 4GB Flash memory with SD card support

The new GL series enables reliable long term measurment with its
built-in 4GB flash memory  and SD card slot for external storage devices.
The SD card slot supports an SDHC  memory card of up to 32GB. 
The captured data can be stored in GBD  (Graphtec binary data) or CSV file format.


Capturing time* (when all 20 analog channels are being used with Logic/Pulse inputs turned off.)

CSV format

*Figures are approximate. File size of captured data is 2GB in GBD or CSV file format on this chart.

Sampling interval is limited by the number of channels in use. (10ms:1ch, 50ms:5ch, 100ms:10ch)

Limited sampling speed is available when digital sensors and GL100-WL are used as a remote monitoring device.

 

Ring capture function

The most recent data is saved when the memory is configured in ring memory mode. (Number of capturing data is 1000 to 2000000 points)

Relay capture function

Data is
continuously
saved to multiple files up to 2GB
without losing any data until capturing
is stopped when the memory is
configured in the relay mode.

 

 



Hot-swapping the SD memory card

SD card can be replaced during data capturing when the sampling interval is 100ms or slower.

 

Useful Functions

 

Displays the data by a bar chart (in firmware ver.1.10 or later)

The integrated data that is measured
by the digital sensors can be displayed
by a bar chart in the GL840 series.

What you can do using the wireless LAN (option)*
Case 1 : Combining GL100-WL and GL840

GL100-WL can now be connected to the GL840 as a remote sensor using
the WLAN feature. You can expand your measurement variety by adding
the sensors available on the GL100-WL unit. The measured value by GL100-WL
will appear in a single file along with the measurement value from the GL840 main
inputs. GL840 will now take in direct information from the GL100-WL units.
GL840 supports up to five units of the GL100-WL.


Application Example : Air conditioning performance test

Easily get the additional information that is required for the
multi channel temperature measurement.

 


Measurement data from GL100-WL,

displayed as a waveform and digital value.

 

Case 2 : Remote monitoring of GL840 by PC or Smart device

Measured data can
be monitored and
controlled via PC or a
