Abstract
A system and method are disclosed for adapting a loop powered wired field instrument for use in a wireless network of wireless field instruments without changing internal wiring of the loop powered wired field instrument. The invention comprises a wired to wireless adapter apparatus that connects to a wired field instrument. The apparatus comprises power conversion circuitry that receives either external power or battery power and converts the received power to loop power for the wired field instrument. The apparatus also receives and decodes a wired signal from the wired field instrument and converts the decoded signal for subsequent wireless transmission to a wireless network. It appears to the wireless network that receives the transmitted wireless signal that the wired field instrument is a wireless field instrument.
