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.

Abstract: A device includes a radio operating on a predetermined schedule, and a battery configured to supply power to the radio for radio operation. A radio controller is configured control to radio operation. A voltage indicating circuit is configured to monitor a voltage of the battery, and to provide an output signal indicative of a battery voltage sufficient to power radio operation. When the output signal is active, the radio controller allows operation of the radio on the predetermined schedule. When the output signal is inactive, the radio controller adjusts operation of the radio to maintain radio operation.

Abstract: A wireless process variable transmitter for use in an industrial process includes a process variable sensor configured to sense a process variable of the industrial process and provide a process variable sensor output. A battery power source includes a plurality of battery power banks each having a primary cell battery, a low voltage cut-off circuit electrically connected to the primary cell battery which provides an electrical connection to the primary cell battery while a voltage of the primary cell battery is above a threshold, and an ideal diode having an input electrically connected to the primary cell battery through the low voltage cut-off and providing a power bank output. A power sharing node has an input connected to the battery power bank output of each of the plurality of battery power banks and having a shared power output which provides power to circuitry of the wireless process variable transmitter.

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.
