Abstract
An environmentally sealed service block is mounted inside a field wiring compartment of a process fluid transmitter. The service block has field wiring terminals, sealed jumper assemblies and sealed pushbutton switches connected to a sealed cable and plug. The sealed plug plugs into a permanently sealed transmitter assembly. High impedance programming circuitry connected to the jumper assemblies and pushbutton switches is completely sealed and not subject to malfunction due to contamination present in the field wiring compartment.
