    Abstract: A field communication apparatus may include a first communication unit and a second communication unit each of which performs communication between a plurality of field devices and a host device, the first communication unit and the second communication unit constituting a duplex unit, a first explosion-proof housing that accommodates the first communication unit, and a second explosion-proof housing that accommodates the second communication unit. The first communication unit may be capable of being removed from the field communication apparatus while being accommodated in the first housing, and the second communication unit may be capable of being removed from the field communication apparatus while being accommodated in the second housing.
