Distributed Control Interface (DCI) block types:

The DCI blocks are configured just like other Foxboro DCS control blocks. The DCI
blocks address and read/write data from/to the addressed field device.
Standard, Rugged Design
The FBM232 has a rugged extruded aluminum exterior for physical and electrical
protection of the circuits. Enclosures, specially designed for mounting the FBMs,
provide various levels of environmental protection, up to Class G3 harsh
environments per ISA Standard S71.04.
Modular Baseplate Mounting
The module mounts on a Modular Baseplate, which accommodates up to four or eight
FBMs. The Modular Baseplate is either DIN rail mounted or rack mounted. The
Modular Baseplate includes signal connectors for the FBMs, provides connections for
independent dc power supplies, I/O cable connections, and 2 Mbps Module Fieldbus
connections.
Easy Removal/Replacement
The module can be removed or replaced without removing power.
