Product Brief Page 1 of 4 GC9838-LR - INTELLIGENT HYBRID PLC-RF DIN RAIL MODEM Overview Power-line communications (PLC) and low-cost Radio Frequency (RF) networking can suffer from high noise and attenuation due to environmental factors which often cause communication links between two nodes to vary significantly in quality. A communication link which may be optimal on certain medium and channel at a given time may become sub-optimal as time passes resulting in breakdown of the network. In certain cases, communication can be totally disrupted due to interferences or breakdown in the medium. For example, in the case of PLC, a transformer or a physical discontinuity in the power line would impede communications while metallic and concrete objects to the extent of weather (humidity, rain, lightning etc.) can block or affect the quality of wireless communication. The gridComm GC9838- L R is a next generation hybrid DIN Rail Power Line Communication - Radio Frequency modem providing complete hardware and software networking solution. It automatically configures the PLC and RF real-time and self-adapts to the varying conditions in the communication links with the most optimal data routing paths, resulting in extremely reliable and robust communications in a Low-Voltage power network. This new generation GC9838-LR DIN Rail hybrid PLC-RF modem utilizes the industry-leading gridComm GC2200 Integrated circuit, an OFDMA (Orthogonal Frequency Division Multiple Access) Power Line Communication Transceiver and a built-in sub-GHz wireless module to allow adaptive networking over different media. The wireless connectivity can be available in LoRa for tree-structure network or gridComm proprietary VE mesh-structure network. Benefits By taking advantage of its inherent 18 independent PLC channels and the additional 19th RF channel, the GC9838-LR is able to communicate over PLC and RF concurrently via gridComm GCNet network. This brings upon the benefits of operating in a single unified communication network using common communication protocol, command sets and ID addressing scheme. This not only enables the GC9838 to serve as an automatic bridge or range extender but, at the same time, also allows it to connect with discrete PLC or RF devices which can be extremely useful in IoT sensor applications. The 18 PLC channels are capable of operating with up to 54 carrier frequencies over a wide frequency range from 5KHz to 500KHz on the power lines whilst the 19th RF channel operates on industrial-strength ISM frequency bands. The new GC9838-LR is capable of communicating via low voltage power network of up to 2 Km in range in either PLC or RF modes. The GC9838-LR is ideal for applications such as Industrial Automation, Automatic Meter Reader (AMR), M2M and other applications that require extremely reliable and robust communication links. The GC9838-LR is also equipped with a set of Digital Input and Dry Contact Relay controlling up to 2KW AC power output. By making use of gridComm GCNet Network Management Command APIs or gridComm PLCM Utility tool1, the user can attach a sensor tied to the Digital Input for trigger-based event scenarios. Likewise, the user can also perform remote On/Off switching for a motor or any electrical device. Note 1: For availability of the Digital Input and Dry Contact Relay GCNet APIs and PLCM Utility tool, please contact gridComm. Auto Network Applications The GC9838-LR is optimized for network topologies such as star or tree configurations (PLC/wireless modes). With gridComm VE wireless module, the RF link layer can be implemented in a “Tree and Mesh” network structure. Figure 1 shows a simple hybrid PLC-RF network system connected with five modems installed in a “Star” configuration. Figure 2 shows a hybrid “Tree” network with PLC and wireless nodes. Figure 3 shows a hybrid PLC and wireless nodes in “Tree and Mesh” network.
