Network Switch – GWNET11
Grain Watch™ Temperature Monitoring System is a set of components used to monitor and supervise the temperature in storage facilities for grains or energy raw materials.
The GWNET11 is a multiplexor for a temperature cable input channel in the GWAB11/12. One GWNET11 makes it possible for a GWAB11/12 temperature cable input channel to handle 4 extra temperature cables making it 5 in total.
The last input can be connected to yet another GWNET11 instead of a sensor cable which then makes it possible for the GWAB11/12 input channel to handle 4 additional temperature cables.
Up to 4 GWNET11:s can be connected like this to one sensor cable input channel in the GWAB11/12 which means that a GWAB11/12 input channel can handle up to 17 sensor cables. This makes it possible for the GWAB11/12 to handle a maximum of 68 sensor cables in total, for all 4 input channels.
