• Number of analog input channels: 20 channels in standard configuration, Expandable up to 200 channels
• Display (LCD): 7-inch TFT color LCD (WVGA: 800 x 480 dots)
• Power consumption: Max. 36 VA

Isolated/Universal input, standalone multi-channel data logger ideal for voltage/temperature measurement on multiple channels.

Accommodates a wide variety of measurements

• Multifunction analog input ports - This contains a highly isolated input mechanism that ensures that signals are not corrupted by noise from other channels. The GL840/240's inputs are suitable for combined measurements from voltage, temperature, humidity, logic, and pulse signals.
• 4 channels of Logic/Pulse inputs - Supports 4-channel logic or pulse signal inputs. Pulse mode allows cumulative, instant, or rotational values for industrial measurement capability with speed and flow.

Large easy-to-read 7-inch wide color LCD(4.3-inch in the GL240)

Carries a clear 7-inch wide TFT color LCD screen (WVGA: 800 x 480 dots) for the GL840, and 4.3-inch wide LCD screen (WQVGA: 480 x 272 dots) for the GL240. Monitoring data can be displayed in waveform or digital form. Parameter settings can be displayed on the screen.

Displays the data by a bar chart

The integrated data that is measured by the digital sensors can be displayed by a bar chart in the GL840 series. Multiple bar chart types are available. Data can also be displayed as a line chart when the GS-TH (Temp/Humidity), GS-DPA-AC with GS-ACxxx (AC current/power) or GS-LXUV (Illuminance/UV) digital sensor is used. The digital sensor can be connected to the GL840 or the GL100-WL. The GL100-WL is used combined with the GL840/GL240. * Firmware ver.1.10 or later.

Alarm output function

Alarm signals can be placed using the four-channel alarm output ports based on set conditions for each channel. *

​* Input/output cable (B-513 option) is required to connect the alarm output ports to the external buzzer/light mechanism.

USB drive mode

USB drive mode function enables data to be transferred to the PC from GL840/GL240 by drag & drop feature.

Built-in 4GB Flash memory with SD card support

The new GL series enables reliable long-term measurement 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.
