The DCS FBMs provide advanced 200 Series FBM

technology on an APACS+ module form factor. Each

DCS FBM plugs into the slot used by the replaced

APACS+ module and provides two rear connectors,

one of which mates to a connector on a local field

termination strip on the backplane of the

MODULRAC.

For marshalled termination assembly located in an

adjacent MODULPAC enclosure, the DCS Fieldbus

Module I/O connector mates to a field termination

cable connector mounted on the back of the

MODULRAC.

The following I/O module types are used in the

APACS+ system:

 Analog input module

 Analog multi-range input module

 Analog RTD input module

 Digital input module

 Digital output module

 HART® input module

 HART redundant input module

 Analog/digital/pulse input and analog/digital

output module, configurable point-by-point

 Analog/digital input and analog/digital output

module, configurable point-by-point

 Digital input/output, configurable point-by-point.

Each module type is replaced with an equivalent

Foxboro Evo DCS FBM module. All I/O wiring

connected to the I/O module termination strips

remain in place. Power is derived from the original

rack power supply. Table 1 lists the available DCS

Fieldbus Modules and the APACS+ modules they

replace.
