3-9900.395 Georg Fischer H COMM Module type 9900
Product Description:
The H COMM Module enables communication between the 9900 and a HART®-enabled device. The HART (Highway Addressable Remote Transducer) Protocol superimposes digital signals on top of the 4 to 20 mA analog signal.
NOTE: With H COMM Module installed, a minimum of 24 V is required for loop-powered systems

Features:
- If the 9900 Base Unit will be mounted in a panel, plug-in modules may be installed either before or after the base unit is mounted.
- If the 9900 Base Unit will be mounted using the accessory wall mount kit (3-9900.392), install plug-in modules fi rst.
- If the Direct Conductivity/Resistivity Module or the 4 to 20 mA Output Module will be included in your unit, install the HCOMM module fi rst, then install the other module over the H COMM module
- To install the H COMM module, carefully align the module pins into its plug (see illustration) and push the module straight in until the tabs on the bottom edge snap into place.
- To uninstall, squeeze tabs, grasp the module and pull straight out.
