OWA GENERAL DESCRIPTION
7.1 Intended Use
The OWA is a key component of the Honeywell Wireless Network for Secure Industrial Application (WNSIA). These
transmitters are available for various sensor types including Digital Inputs, Temperature, High Level Analog Inputs, Pressure
and Corrosion. The OWA uses a low-powered ISA100 2.4 GHz radio to communicate with Radio Infrastructure and Gateway
devices that are connected to a wired DCS network.
