摘要: A process device includes a controller and a wireless communications module. The wireless communications module is coupled to the controller. A power generation module is provided to generate electricity for the process device. The power generator module can be disposed within the process device or it can be a separate unit coupled to the process device.

摘要: A process variable transmitter connects a serial bus to an accessory load. A supply limiter circuit provides a first supply current limit and provides a stored energy output. A recessive driver circuit draws a drive current from the stored energy output and couples the drive current to the serial bus. The recessive driver circuit provides a drive current limit. A dominant driver circuit has a dominant state in which it conducts the drive current, and an inactive state in which the drive current is available to the accessory load.
