Wireless Network Components
The Wireless Transducer Network consists of one or more RF Wireless Nodes (A) to which signals, sensors or transducers (B) are connected. These Nodes can be located 100’s of yards to miles from the IntelliLogger (C) location depending on your application needs and the RF environment. The Nodes run autonomously from local power supplies or batteries, periodically sampling their inputs and communicating the input values back to an RF Gateway radio (D) at the IntelliLogger™ location. This Gateway radio is connected to the IntelliLogger via a Modbus interface and an SCC-1 RS-485 to RS-232 converter (E).

Operation
As the IntelliLogger data acquisition instrument is operating, executing a user defined Program Net , it reads the values from the Gateway memory that have been received wirelessly from the remote RF Nodes and uses these signal readings for data acquisition, alarming, reporting, calculations, etc. At the same time as the IntelliLogger is reading and processing the RF connected Node values, it can also be sampling other analog and digital inputs (F) that are wired directly to its integral analog and digital input channels.

Wireless Nodes
A variety of Nodes are available to interface to various types of signal and sensor inputs.. as well as provide local outputs. RTD’s, Vdc, mAdc, thermocouple, count, frequency and digital (on/off) signals are all compatible. Nodes typically have a mix of I/O and have various power options allowing the Node to operate from internal or external batteries, photovoltaic power or other Vdc power.
