Main features

All channel Isolated/Universal input, Standalone Multi-Channel

Its compact size contains an isolated input system which ensures that signals are not corrupted by inputs to other channels, thus eliminating wiring concerns. The GL240s multi-type inputs are suitable for voltage, temperature, humidity, pulse, and logic signals, enabling combined measurements of different phenomena like temperature/humidity and voltage.

Voltage 20mV - 100V , 1-5 V/F.S.
Thermocouple Type: K,J,E,T,R,S,B,N,and W(WRe5-26)
Humidity 0 to 100% RH- using the humidity sensor (option B-530)
Pulse 4ch Rotation count (RPM), Accumulating count, Instant count
Logic 4ch

Maximum sampling interval of up to 10ms

Provides faster sampling rates for voltage measurements. You are able to achieve up to 10ms sampling speed when limiting the number of channels in use.

Sampling Interval 10ms 20ms 50ms 100ms 200ms 500ms 1s 2s
Number of channel 1 2 5 10 20 50 100 200

Supports large-size SD memory card for reliable long term measurement

New GL240 series carries two SD memory card slots for storage device. The SDHC type SD memory card is supported up to 32GB. 4GB SD memory card comes as a standard accessory installed in the first slot. the captured data can be stored in GBD(Graphtec binary data) or CSV file format.

Sampling 10ms 50ms 100ms 200ms 500ms 1s 10s
GBD format 41 days 88 days 103 days 207 days Over 365 Over 365 Over 365
CSV format 3 days 11 days 16 days 36 days 91 days 182 days Over 365
* 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)

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 Alarm


Alarm output function

Based on set conditions for each channels, alarm signal can be placed using the four channel alrm out put ports.*
*Input/Output cable(B-513 option) is required to connect the alrm output ports to external buzzer/light mechanism.

USB drive mode

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

Easy-to-read 4.3-inch wide color LCD

Carries a clear 4.3-inch wide TFT color LCD screen (WQVGA:480×272 dot)for the GL240. Monitoring data are displayed in waveform or digital form option. Parameter settings can be displayed on the screen.

3 Types of power source

Choose from AC power supply, DC supply* or the rechargeable battery pack.*
*DC power drive cable(B-514) and battery pack(B-569) are optional accessories.

Networking features

WEB&FTP server function
GL240 can be controlled externally via a network on the WEB browser, which also supports monitoring and transfer of signals and captured data. FTP client function Captured data is periodically transferred to the FTP server for backup. NTP client function The clock on the GL240 is periodically synchronized with the NTP server. *The GL240 needs to be connected to a LAN enviroment using the available WLAN ports for above functions.
