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).

| 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.

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.
Digital sensors and input terminal/adapters for the GL100
connects to the GL840 directly
Supports 4-channels logic or pulse signal inputs. Pulse mode allows cumulative, instant,
or rotational values for industrial measurement capability with speed and flow.
Provides faster sampling rates for voltage measurements. Up to 10ms sampling speed
is achievable when limiting the number of channels in use.

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.)

*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.
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.
SD card can be replaced during data capturing when the sampling interval is 100ms or slower.
Useful Functions
The integrated data that is measured
by the digital sensors can be displayed
by a bar chart in the GL840 series.
