Abstract:
A field device comprises a transducer, a photodetector, a display, and a display controller. The transducer controls or monitors process variable, and the display shows information relating to the process variable. The photodetector detects a light level. The display controller is capable of switching the display on and off in response to changes in the light level detected by the photodetector.
Abstract:
An industrial process field device (200) has a housing (202) with a wall (204) . The wall has a feedthrough opening (207) between a battery compartment (208) and an electronics compartment (206) . A feedthrough connector (230) seals the feedthrough opening and includes a power connector (234,236) connected to industrial process field device electronics (212) . A battery assembly (216) includes a battery housing with a battery connector (244) , and includes a battery (242) and an energy limiter (240) connected to the battery connector. The battery connector mates with the power connector to energize the industrial process field device electronics. A seal (250) seals the mating connection of the power connector and the battery connector.
Abstract:
A wireless field device (12) for use in an industrial process includes input/output terminals (40) configured to couple to a process interface element (16). A discrete input/output channel (24) is configured to receive a discrete input from the process interface element through the input/output terminals (40) when configured as a discrete input channel. The discrete input/output channel (24) is further configured to provide a discrete output to the process interface element (16) through the input/output terminals (40) when the discrete input/output channel (24) is configured as discrete output channel. Wireless communication circuitry (48) is configured to transmit and receive information. A controller (44) communicates information through the wireless communication circuitry (48) and operates in accordance with configuration information to configure the input/output channel (24) as an input channel when the input/output terminals (40) are connected to a discrete process variable sensor, and further configure the discrete input/output channel as a discrete output channel when the input/output terminals are coupled to a discrete control element.
