Graphtec GL240 is a third-generation data logger product with exceptional price/performance. It’s a 10 analog channel device augmented by four discrete inputs and outputs. Its discrete inputs can be configured as a group to be either logic inputs or pulse inputs. When configured for pulse, each of the four channels can be configured to measure frequency or to count. The four discrete outputs are alarms that can be triggered by a variety of easily-defined analog and pulse/discrete input channel conditions. The 10 GL240 analog input channels may each be configured to measure a direct connected voltage in the range of 20 mV to 100 V full scale across 12 ranges, or for a direct-connected thermocouple of any type to measure temperature. Each of the GL240’s analog input channels is electrically isolated from other channels and from power ground allowing off-ground measurements using shunts, as well as powered or grounded thermocouples.
The most powerful GL240 feature is its triggering flexibility. Data recording can be independently started or stopped as a function of analog and pulse/discrete signal level (single or windowed), alarm, date and time, and day-of-the-week. Triggers can also be configured to operate only once, or to automatically repeat. The ability to of the GL240 to adapt to virtually any desired trigger condition allows the instrument to operate unattended for long periods of time with complete autonomy.
The GL240 operates either connected to a PC or entirely stand-alone. Connection to a PC may be over a standard USB or optional wireless connection. Either connection approach may take advantage of supplied PC-side software to configure, acquire, display, and record digitized information for storage directly to the PC’s HDD. Acquired data may be retrieved for review and analysis after recording, including the ability to export to Microsoft Excel. Using the GL240’s wireless option enables the instrument’s networking features, allowing it to be remotely configured and managed using the standard Web browser of any computer or smart phone. Automatic backup of data acquired to a user-accessible SD memory card is also supported via its FTP facility.
Finally, the measurement reach of a wireless-enabled GL240 is further extended by use of the GL100 accessory. The GL100 wirelessly enables measurements of temperature/humidity, acceleration, CO2, illuminance, ac current, and more. Communicate with up to (1) GL100 unit with B-568 Wifi module
Sampling interval
This is used to set the sampling interval for data capture.
The table below shows the number of measuring channels*1 and sampling interval values that can be set.If data fluctuate due to noise, set the sampling interval to a value which enables the digital filter function.
| Number of Measuring Channels*1 | Allowed Sampling Interval | Sampling Interval which enablesDigital Filter |
| 1CH | 10ms or slower*2 | 50ms or slower |
| 2CH | 20ms or slower*2 | 125ms or slower |
| 3CH to 5CH | 50ms or slower*2 | 250ms or slower |
| 6CH to 10CH | 00ms or slower | 500ms or slower |
*1: «Number of Measuring Channels» is the number of channels in which input settings are NOT set to «OFF». (CHs in sensor and wireless sensor connected through the wireless unit are not included.)
*2: When the temperature setting is performed in 10, 20, or 50 ms sampling interval, the data capture cannot be performed
GGL240 Analog Input Circuit and Measurement Ranges
Each of the ten GL240 analog input channels offers isolation between them and ground. That means that a potential difference in the ground of one or more channels relative to each other, or relative to the power ground of the GL240 have little or no effect on measurements when used within spec. The isolation feature provides a tremendous advantage in terms of noise immunity while making typical measurements, and extends the reach of the instrument to include those that can only be made with an isolated configuration, like current shunts and powered and grounded thermocouples.
GGL240 Discrete I/O and Pulse Inputs
Depending upon the application, discrete I/O and pulse inputs can play a crucial data logging role. The GL240 supports four discrete alarm outputs that can signal alarm or event states that are a function of virtually any combinations of analog and pulse or discrete input values. These alarm outputs may be used to handshake with a PLC or other devices to start or stop processes or simply signal the beginning or end of events. The GL240 also offers four discrete input ports, which may be configured as simple binary true/false input flags, or for pulse and counter inputs. Pulse inputs can be used to acquire frequency data such as rpm or flow, or reconfigured to acquire count data to derive volume from flow or simply count the number of iterations from a process. Pulse data is neatly folded into acquired analog data so that all measured parameters can be evaluated in the same timeframe during analysis to easily identify cause and effect. A final discrete input is reserved for externally triggering the GL240’s A-D conversion to allow the instrument to synchronize to external processes. Access to all discrete I/O requires the B-513 cable option.
Wireless measurement using wireless LAN (option)
Wireless LAN option enables the wireless communication with other device.When the GL240 is set as a station, PC and smart devices will be able to access the WLAN unit directly.
Combining GL100-WL and GL240
GL100-WL cab now be connected to the GL240 as a remote sensor using the WLAN feature.GL240 supports 1 unit of the GL100-WL.
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.
Maximum sampling interval of up to 10ms
Provides faster sampling rate 10ms for voltage measurement.
Supporting large size SD memory card for reliable long term measurement
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.
