Features and Benefits

Mini-Change

Micro-Change

Molex releases the Brad Mini-Change and Micro-Change molded connection systems for fast,

error-free Foundation Fieldbus installations

Foundation Fieldbus is a communication protocol used

to interconnect field-level instrumentation and control

devices to a PLC (Programmable Logic Controller)

or DCS (Distributed Control System) controller in

a process automation control system. Foundation

Fieldbus is employed in the control systems of oil & gas

production, refineries, petrochemical plants, chemical

manufacturing and pharmaceutical manufacturing.

At the physical-layer level, Foundation Fieldbus allows

multiple devices to communicate digitally over the

same wire. The Foundation Fieldbus physical layer,

i.e., cable/transmission signal requirements, is

specified in the ISA SP50.02 and IEC 1158-2 standard

for fieldbuses. The cable specifications are listed in

the Cable Standard FF-844 , which is issued by the

Fieldbus Foundation, the organization that controls

and maintains this open standard. Brad Foundation

Fieldbus products from Molex are fully complaint to

these specifications.

Brad Foundation Fieldbus products from Molex are

based on the proven Mini-Change and Micro-Change

circular, circular connector families. These sealed,

watertight connectors offer the ruggedness required

in the most demanding industrial applications. The

pre-wired, keyed connectors provide a modular

wiring system that is not prone to field wiring

termination errors.
