Refer to each component’s Product Data Sheets for the approvals
options for hazardous locations.
Physically, the FB100 consists of a termination module with optional
I/O points, RAM battery backup board, optional Comm 2
communications module, processor module, battery charger module,
backplane, and optional display housed in a compact, weather-tight
case. The FB100 is packaged in a NEMA 4 windowed enclosure that
mounts on a pipestand, to an orifice plate via a 3- or 5-valve manifold,
to a turbine meter, or to a rotary meter. The aluminum alloy enclosure
protects the electronics from physical damage and harsh environments.
Refer to Figures 1-1 and 1-2.
