    摘要: A remotely powered field instrument comprises a housing with an electronics compartment, a terminal compartment, and a bulkhead separating the electronics compartment from the terminal compartment. A first electrical lead extends through the bulkhead. A mounting plate is secured within the terminal compartment. An interface module is positioned within the terminal compartment and secured to the mounting plate. The interface module comprises an optical connector, an optical-to-electrical converter coupled to the optical connector and a second electrical lead coupled between the optical-to-electrical converter and the first electrical lead.
