Abstract:
A two-wire field-mountable process device comprising:a power module couplable to a two-wire loop and adapted to wholly power the process device with power received from the two-wire loop; a loop communicator coupled to the power module, and being couplable to the two-wire loop to communicate on the two-wire loop; a controller coupled to the loop communicator and power module; a first input channel operably coupled to the controller and the power module, the first channel configured to couple to at least a first sensor for receiving at least one sensor input; and a second input channel operably coupled to the controller and the power module, the second channel being configured to couple to at least a second sensor for receiving at least one sensor input; and wherein the first and second channels are substantially electrically isolated from each other and from the two-wire loop.
