The SenzaGate and SenzaCoordinator families provide protocol translation and connectivity between the SenzaNET network and backend systems. The SG131 is a compact gateway with interfaces for the most widely used serial and industrial fieldbusses built in. The SG150 is primarily designed for deployment in remote locations where no IT infrastructure exists. It optionally includes a GSM/GPRS modem for cellular backhaul, and the extra large 64 MByte buffer ensures that no sensor readings are discarded even in the event of a temporarily lost or weak signal. The SenzaCoordinator SC130 provides simple, inexpensive serial connectivity to a host.

The SG132 family provides an instant cable replacement solution, allowing users to bridge the communication of I/O modules over wireless. Analog or digital sensor data collected by a SenzaBlock adapter is wirelessly transmitted and re-created as output signals by the SG132 or SG132lite for processing by control panels, PLCs or data loggers. In addition, the SG132 comes with the ability to receive analog control signals, and wirelessly relay these signals to a compatible SenzaBlock adapter where they can be re-created as outputs to an actuator. The mapping between SenzaBlock and gateway channels is fully configurable through the USB maintenance port, using the included Windows configuration and management tool.

 

As implied by its name, the SenzaHub can repeat wireless signals to enhance and extend coverage. It does not increase the number of channels, but merely operates in the background, continuously listens to incoming traffic from neighboring SenzaNET nodes, and re-broadcasts traffic on the same frequency and within the same time slot. Deployment of SenzaHubs can therefore be particularly useful for expedited delivery of time-critical alarm messages. SenzaHubs automatically establish connections to adjacent SenzaBlock and SenzaGate devices and do not need a network connection, making them very easy to install and maintain.
