A field-mounted process device with multiple isolated connections includes a connection that can be an input or an output. The given input or output can couple to multiple sensors or actuators, respectively. The process device can be wholly powered through its communication I/O port. The process device includes a controller adapted to measure one or more characteristics of sensors coupled to an input connection and to control actuators coupled to an output connection. The controller can be further adapted to execute a user generated control algorithm relating process input information with process output commands.

Field-mounted process device

An interface module for use in a process monitoring and control system has an Ethernet port, a controller, and at least one segment I/O module. The Ethernet port is adapted to send and receive signals in an Ethernet protocol over a cable comprising a plurality of wires and to receive a voltage potential from at least one pair of the plurality of wires. The controller is coupled to the Ethernet port and powered from the received voltage potential. The at least one segment I/O module is coupled to the controller and is adapted to couple to an associated field device segment with at least one attached field device. The at least one segment I/O module is adapted to interact with the at least one attached field device on the associated field device segment.

Interface module with power over Ethernet function

A system couples fieldbus data from a fieldbus line to a network line. The system includes a data format converter that converts the data to USB data. A coupler that includes a first insulating barrier is coupled in cascade with the converter. A host receives the USB data. The host has a data server interface and a network connection. The data server interface presents the data to the network line. A regulator couples power between the host and the fieldbus line with the regulator including a second insulating barrier. Data and power are isolatingly coupled between the fieldbus line and the network line.

Isolating system that couples fieldbus data to a network

A transmitter for use in a process control system for monitoring an industrial process includes a housing having a top and a bottom and a height extending therebetween. A parallelogram display is mounted to the housing. Sides of the parallelogram display are arranged at angles relative to the height of the housing.
