The GL240 is a 10 channel comprehensive data logger and the best value market leader. This compact, comprehensive datalogger accepts voltage, temperature, humidity, pulse and logic signals. Channel-to-channel isolation means wiring errors or overloaded channels do not affect neighbouring channels. Sensors are connected via rear mounted screw terminals.
Multifunction Analog Input Ports
Contains a highly isolated input mechanism which ensures that signals are not corrupted by noise from other channels. The GL240'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 4.3 in. Wide Color LCD
Carries a clear 4.3-inch wide LCD screen (WQVGA: 480 x 272 dots. Monitoring data are displayed in waveform or digital form. Parameter settings can be displayed on the screen.
Alarm Output Function
Based on set conditions for each channels, alarm signals can be placed using the four channel alarm output ports.
*Input/output cable (B-513 option) is required to connect the alarm output ports to external buzzer/light mechanism USB drive mode
USB Drive Mode
USB drive mode function enables data to be transferred to the PC from GL840/GL240 by drag & drop feature Navigation function.
Simple to use navigation screen allows setting operation for measurement and wireless LAN adapter.
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.
Supports Large SD Memory Cards for Reliable Long-Term Measurements
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.
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 SD Memory Cards
SD card can be replaced during data capturing when the sampling interval is100ms or slower.
3 Types of Power Sources
Choose from AC power supply, *DC supply, or the *rechargeable battery pack.
*DC power drive cable (B-514) battery pack (B-569) are optional accessories
Web & FTP Server function
The GL-240 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 GL840/Gl240 is periodically synchronized with the NTP server.
*The GL840/GL240 needs to be connected to a LAN environment using the available Ethernet/WLAN ports
