GL840 Description
Model GL840 Series is a third-generation data logger product with exceptional price/performance. It’s a 20 analog channel device expandable to 200 channels, 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 20 GL840 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, a direct-connected
thermocouple of any type, or a 3-wire PT100 or PT1000 RTD. Each of the GL840’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. Further, two GL840 versions are available to tolerate up to a 60 or 300 Vp-p common mode
voltage. Model GL840-M supports up to 60 Vp-p common mode. Model GL840-WV supports up to 300 Vp-p common
mode to address more aggressive applications, like stacked battery cell measurements for both temperature and voltage.
The most powerful GL840 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 of the GL840 to adapt to virtually
any desired trigger condition allows the instrument to operate unattended for long periods of time with complete autonomy.
The GL840 operates either connected to a PC or entirely stand-alone. Connection to a PC may be over a standard Ethernet, USB, or optional wireless connection. Each 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 GL840’s
built-in Ethernet port or 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 the GL840 is further extended by use of GS Sensor accessories that can be either connected directly to the GL840 or wirelessly accessed with the B-568 wireless option using the GL100-WL. Extended measurements of temperature/humidity, acceleration, CO2, illuminance, ac current, and more are available using GS Sensors.

GL840 Analog Input Circuit and Measurement Ranges
Each of the twenty GL840 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 GL840 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.

GL840 Analog Channel Expansion
The included base analog channel count of 20 channels can be expanded in 20-channel increments to a total of 200, and
the GL840 supports various options to accomplish this. At a minimum you’ll need one of two types of Terminal Units, an
Extension Terminal Base Unit, and at least one of two cables. The expansion process begins by removing the GL840s included Terminal Unit. Next, the removed Terminal Unit is attached to a Extension Terminal Base Unit and paired with one
or more other assemblies depending upon the desired analog channel count. The assemblies are cabled back to the GL840
to complete the expansion.

GL840 Discrete I/O and Pulse Inputs
Depending upon the application, discrete I/O and pulse inputs can play a crucial data logging role. The GL840 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 GL840 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 GL840’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.

SD Memory Card and Wireless Option Access
The GL840 supports two SD memory slots. SD Card 1 is provided with a 4 GB SD memory for data recording. Any
SDHC memory card can be used to a 32 GB capacity. SD Card 2 can be populated with a secondary SD memory card,
or with the B-568 wireless option. Model B-568 enables the networking features of the GL840, and its installation in a
secondary SD slot without affecting the primary SD slot does not compromise the GL840’s storage capacity. The wireless option supports IEEE 802.11b/g/n with the following security protocols: WEP64, WEP128, WPA-PSK/WPA2-PSK,
AKIP/AES. The B-568 wireless option may be configured as either an access point to allow peer-to-peer communication
(such as with the GL100-WL data logger option), or as a router-managed device on a LAN.

Connecting the GL840 Directly To A PC
Don’t need a wireless or hard-wired LAN? No problem. The GL840’s integral USB port allows it to connect directly to a
PC on to which is typically installed the included Graphtec APS software for real time data acquisition.
Ethernet Connection
Use a crossover cable when connecting the GL840 directly to a PC. Otherwise, a standard Ethernet cable can be used.
Internal Battery Pack Option B-569
The GL840 supports one or two battery packs, option (B-569), that allows operation independent of ac power. A fully
charged battery allows an operating time of 5 hours (one battery pack) to 10 hours (two battery packs) depending upon
data logging configuration. The battery can also operate as a UPS (uninterruptable power supply.) In the event that ac
power is lost, the GL840 will seamlessly continue operation on battery power without data logging disruption.

GL840 Analog Measurement Modes
The GL840 in tandem with the optional GL100-WL wireless add-on or its GS Sensor accessories is capable of a remarkable range of measurements. Measurements that the GL840 can make on its own are voltage, 4-20 mA process current
(with optional R250 shunt resistor), thermocouple, RTD, and humidity (with optional B-530 sensor.) When a GL100-WL
is added to the mix (requires the optional B-568 wireless interface), the GL840 has wireless access to an additional range
of measurements. Without the wireless option or the GL100-WL, the GL840 directly accepts GS Series add-on modules.

“Ring Capture” and “Relay Capture” Explained
In addition to continuous data logging, the GL840 supports two special-purpose recording modes: Ring and Relay Capture.
The Ring Capture feature allows the GL840 to acquire a definable number of data values to consecutive data files while
automatically deleting the oldest file. For example, if 1,000 data points are specified, data is acquired to File 1 until 1,000
data values have been recorded. Recording then seamlessly continues to File 2 for another 1,000 values. Before data
recording continues to File 3 for another 1,000 data values, File 1 is deleted. When File 3 is full, File 2 is deleted and recording continues to File 4. This process continues until recording stops. In this manner Ring Capture allows data logging
to continue indefinitely without concern for filling the target memory. Further, since the number of data values recorded
to each file and sampling interval are definable and constant, the timeframe before data is erased is precisely known in
advance. Thus, all critical data leading up to, during, and after an event can be captured for analysis. Maximum file size is
2 GB, but SD memory sizes as large as 32 GB are supported.
The Relay Capture feature of the GL840 is almost identical to Ring Capture, except that data files are never deleted. The
feature essentially exchanges unlimited record time for an entire history of recorded data. Like Ring Capture, maximum
file size is 2 GB, but SD memory sizes as large as 32 GB are supported.
“External Sampling” Explained
Sometimes asynchronous sampling rates just won’t do. If you need to acquire data at a precise moment that’s coincident
with an event, and you can generate a trigger signal for that occurrence, External sampling can be used. The following diagram describes the timing relationship between the various components that define an externally triggered application.
330-668-144412www.dataq.com
Start or Stop Recording on Any Trigger Condition
The GL840’s range of stop and start trigger conditions is massive and unrivaled. Select from single or windowed levels to
the day and time of the week with everything in between per pulse or analog channel. Want to start or stop acquiring data
when the signal level on channel 1 is above 200 psi, but only on Saturday at 12 noon? No problem. Finally, select Boolean
AND/OR operators to tie any variety of trigger conditions together.
Finally, trigger conditions can be independently set for the GL840’s alarm output ports as a function of virtually any combination of analog or pulse input values. The following table describes the array of GL840 trigger conditions to stop, start,
or alarm the instrument:
