A project I was involved in some 5 years ago had field controllers from foxboro and from endress+hauser, however they were fully pneumatical so we used I/P and P/I converters (Eexia) from samson to convert the measurements to pneumatical (0.2 - 1 bar) and the outputs to electrical (4 - 20 mA).
Allen Bradley has Flex Ex I/O suitable for Class1 Div1 installation. They have discrete I/O as well as analog input and output modules. You can use a Controlnet Ex adaptor module for interfacing between the Flex Ex modules and the PLC.
