GX70SM wireless input unit for SMART 920

The wireless GX70SM remote data logger allows for quick and convenient data collection in areas that are not easily accessible or expensive to wire to.

The GX70SM wireless input unit is a compact, battery-powered analog input module that uses 920 MHz radio link to connect to a SMARTDAC+ GX20, GP20, or GM10. The GX70SM allows for the collection of a variety of data points from locations that cannot be easily reached or are difficult and expensive to access. The optional humidity sensor and its simple mounting options makes this ideal for monitoring environmental conditions in areas like warehouses, clean rooms, and inside working environments where heat-related workplace injuries are a concern.

You now can see everything critical to your process: log key data points, monitor current process status, unreachable remote point, and more.

Application examples

Note: The use of SMART 920 enabled units is limited to the United States, Korea and Japan. Please refer to the instructions for proper installation and use.

Details

Battery Powered

battery powered remote data logger

A pair of standard CR123 batteries will power the GX70SM module for 5 years when configured for a measurement once every 5 minutes. The module can also be powered from the USB port for long term or high speed data collection.

Displays the GX70SM battery status on trends, numeric, bar graph, and other monitor screens.

Multiple Inputs

The wireless module has 2 standard universal inputs and 1 dedicated input for relative humidity measurement.
The universal input channels support thermocouples, RTDs, DC voltages, current (with an externally mounted resistor) and digital inputs.

Input Calibration

The module inputs can be calibrated by the customer when routine calibration is required for compliance.

Secure Data

secure data

Wireless Terminal Authentication blocks unauthorized access. It also provides industrial grade AES-128 signal encryption to prevent tampering and wiretapping.

Can be installed in a variety of locations

  • Can be hung on a wall screw.
  • Can be directly mounted to a wall or their flat surface.
  • Can be placed on any ferrous item with the strong embedded magnet.
  • Can be placed on any flat surface.

Can be installed in a variety of locations

 

Extensive self-diagnosis

  • The status of the module can be displayed on the master unit. Conditions such as low battery and sensor burn out can be detected.
  • The signal strength of the module can easily be detected by the base unit to assist in module placement.   

Advanced data backup  New

  • In case of data loss due to communication failure, you can use the automatic backfill tool (application software) to compensate for the missing parts.
  • The module can retain 9000 points* of logged data onboard.
  • If the wireless connection is interrupted for any reason, the missing data can be restored from the GM70SMs memory.

* 30 days at a 5-minute scan interval

Data Backup

Validation documents  New

  • Additional verification protocols are available for the GX70SM wireless module. They can be combined with the SMARTDAC+ validation document (sold separately). You can reduce validation man-hours by using the GX70SM validation document, 773230/W.

You can visualize data in areas without power where environmental management is important.

Pharmaceutical warehouse temperature mapping and continuous monitoring  New

The wireless input unit (GX70SM) provides a continuous temperature mapping and recording solution in product storage areas. Plus, it can continuously monitor risk points throughout the warehouse.

Measuring the WBGT value (heat index) with the SMARTDAC+

What is the WBGT (heat index)?

The GX70SM wireless input unit is battery powered, has a built-in humidity sensor, and supports user-calibration.

This is an index proposed in the US in 1954 for preventing heatstroke. A dedicated measuring device using a black bulb is required for accurate measurement, but in locations without direct sunlight such as factories and offices, the WBGT value can be easily determined from the temperature and humidity.

Flexible wireless communication

  • Communication between the main unit and a SMART 920 remote unit can be established up to approximately 1 km in line of sight.
  • The intelligent mesh network automatically recognizes unstable wireless links and re-routes data to a clear channel.

Reduced installation costs

Mounting conduit and pulling wire is no longer necessary. Installing a wireless solution greatly reduces installation time and costs.

Flexible wireless communication

Multiple mounting options

Wireless I/O components have multiple mounting options to match the conditions at the field location. Components can be DIN rail mounted, wall mounted, set on wall screws, set on a desktop, or attached to a ferrous surface with a magnet. These options provide for system flexibility allow changes to be quickly implemented.

Long distance data acquisition is possible

A 920 MHz wireless signal has a longer range than one in the 2.4 GHz band, typically used in wireless LAN applications. It has a greater reach around obstacles making it favorable for long distance or highly obstructed environments. Up to 0.5 mile line of sight.

 

You now can see everything critical to your process: log key data points, monitor current process status, unreachable remote point, and more.
