Abstract: A wireless field device for use in an industrial process includes input/output terminals to couple to a process interface element and a discrete input/output channel configured to receive a discrete input signal from the process interface element through the input/output terminals when configured as a discrete input channel, the discrete input/output channel further configured to provide a discrete output to the process interface element through the input/output terminals when configured as discrete output channel. Wireless communication circuitry transmits and receives information. A controller transmits information through the communication circuitry based upon a sensed process variable, provides a discrete output signal when the discrete input/output channel is configured as a discrete output channel and receives a discrete input signal when configured as a discrete input channel. An external power supply input is couples to an external power supply and a battery power supply input couples a battery. Power supply circuitry powers the controller from at most one of the external power supply or the battery.

Abstract: A wireless field device for use in an industrial process includes input/output terminals configured to couple to a process interface element. A discrete input/output channel is configured to receive a discrete input signal from the process interface element through the input/output terminals when configured as a discrete input channel. The discrete input/output channel is further configured to provide a discrete output to the process interface element through the input/output terminals when configured as discrete output channel. Wireless communication circuitry transmits and receives information. A controller is configured to provide a discrete output signal to the process interface element in response to information received by the wireless communication circuitry when the discrete input/output channel is configured as a discrete output channel, and further configure to receive a discrete input signal from a process variable sensor and responsively provide an output using the wireless communication circuitry when the discrete input/output channel is configured as a discrete input channel. An external power supply input couples to an external power supply. A load adapter module couples to the discrete output signal and the external power supply input and includes a switch configured to connect the process interface element to the external power supply in response to the discrete output signal.
