TRICONEX TRIPLE MODULAR REDUNDANCY

Tricon operation is based on the principle of safety and high plant availability, which identifies and

compensates for failed control system elements and allows on line replacement while continuing

its assigned task without interrupting the controlled process. Fault Tolerance is achieved through TMR technology.

TMR employs three isolated, parallel control systems and extensive diagnostics integrated into one

system. The Tricon system uses two-out-of-three (2oo3) voting to provide high integrity, error-free,

uninterrupted process operation with no single point of failure. Setting up applications is simplified

with the Tricon, because the TMR system operates as a single control system from the user’s point of

view. The extensive diagnostics are inherent and transparent to the programmer.

Use of the Tricon continues to expand into new industries and applications as customers require

increased system safety and/or high availability. Today, Invensys has delivered and installed Triconex

safety system solutions in over 70 countries, providing increased safety and high process uptime.

External Termination Panels

An external termination panel (ETP) is an electrically-passive printed circuit board (PCB) to

which field wiring is easily attached. A panel connector, terminal blocks, and optional

components are mounted to the PCB and enclosed in a DIN-rail compatible plastic housing. A

termination panel and associated cable pass input signals from the field directly to an input

module, or pass output signals from an output module directly to field wiring. This

arrangement permits the removal or replacement of I/O modules without disturbing field

wiring.

Standard termination panels are best for remote marshaling of field wiring where maximum

flexibility, high density and simple maintenance is desired. Standard termination panels allow

you to marshal field signals in a separate enclosure up to 99 feet (30 meters) from a Tricon.

A standard termination panel consists of a PCB with all necessary components—such as two

piece terminal blocks, resistors, fuses and blown-fuse indicators—mounted on a DIN-rail

compatible plastic housing. The housing snaps into mounting rails in accordance with

DIN 50 22.

Compression terminals on the standard panel are designed for use with 24- to 12-gauge (0.3

mm2 to 2.1 mm2) wiring. Some panels have an optional current-limiting series resistor, others

have a fuse with a blown-fuse indicator, to protect the field wiring and field device.

Standard termination panels are pre-configured for a specific application. For instance,

commoned standard termination panels can be ordered with commoned power-and-return, or

redundant DC power configurations with a diode-ORing. The thermocouple input termination

panel provides cold-junction temperature sensors and can be ordered with upscale, downscale,

or programmable burnout detection. A standard termination panel for analog voltage inputs

provides commoned or non-commoned signal returns, while the current-mode version has a

precision resistor at each input point to convert current to voltage.

Each standard termination panel is packaged with a matched interface cable that connects the

panel to the backplane of a Tricon chassis. A female connector at one end of the cable is keyed

to match the male connector on the Tricon backplane. A male connector on the other end of the

cable attaches to the standard termination panel.

In addition to standard termination panels, there are other types of termination panels,

including:

• Basic termination panels

• Hazardous location (nonincendive) termination panels

• RG 1.180 Termination Panels

• Termination panels with interposing relays

• Bypass panels for digital inputs

• Termination panels with RTD/TC/AI input signal conditioning

• Termination panels for 3603B digital output modules

• Termination panels for 3806E analog output modules
