Abstract:
1. An apparatus comprising a power assembly for use in powering a 2-wire powered field device for operation to configure or test by digital bus network communication comprising power supply circuitry for converting a source voltage into nominal 24-volt DC output voltage; a plurality of input power connections between the source voltage and power supply circuitry; a network load means for electrically conditioning a communications pathway between a network communications interface and a field device; a plurality of output power connections between the power supply circuitry output voltage and the network load means; a plurality of network interface connections between the network communication interface and the network load means; a plurality of field device connections between the network load means and the field device for conducting power to the field device and conducting network communication signals between the network communication interface and the field device; wherein the plurality of source voltage connections and a plurality of network interface connections are arranged within the apparatus to permit the plurality of field device connections to provide the output voltage to the field device and further to conduct communication signals between the field device and the network communication interface and wherein the power supply circuitry and network load means are contained within a common casing; and wherein the common casing secures the plurality of source voltage connections, the plurality of network interface connections, and the plurality of field device connections.
