Triconex Model 3482 High-Current Analog Output Module

grounded, and the Tricon is operating normally, the wiring and attached devices will not

release sufficient energy to cause ignition in the specified flammable atmosphere.

Termination Panels with Interposing Relays

Termination panels with interposing relays can be used with most digital output modules and

are recommended for these applications:

• Load currents greater than 2 amps

• Field voltages greater than 115 VAC

• Voltage-level conversions

• Motor-starter circuit compatibility

Interposing relay panels are available in these configurations:

• 16-point c

ommoned

• 16-point non-commoned

The digital outputs of the interposing relays are not fault-tolerant. However, each relay

provides an auxiliary contact that can be fed into a digital input to send a loopback signal to the

control program. A user-written loopback check in the control program can ensure that the relay

has achieved its commanded state. The loopback cable must be ordered separately.

Each interposing relay panel provides the capability to common power and return through a

factory-mounted bus-bar arrangement.

Each interposing relay panel consists of:

• A 7 in x 19 in (36 cm x 48 cm) rack-mountable panel with terminals for 16 digital

outputs and 16 digital inputs.

• Two ELCO connectors mounted on the panel for connecting to digital input modules

using digital input cables 9141-010. 9142-010. or 9143-010.

• An EIA standard RS-310-C plate on which the termination panel is mounted.

• A digital output module and a cable compatible with the selected coil voltage.

Managing operational risks with confidence

The Tricon fail-safe and fault-tolerant controller is used extensively in high-hazard industries

where safe operations are critical and reliable operation is paramount.

In particular, the Tricon system is the only commercial off-the-shelf controller approved by

the Nuclear Regulatory Commission for Nuclear 1E applications.

Our safety and critical control solutions are supported by a dedicated team of TÜV-certified FunctionalSafety Experts and Engineers,

deplo yed globally, ensuring that expertise is always available where and when required.

A powerful, scalable design with assurance of continuous operation,

the Tricon system complies with international standards such as IEC61508 and fulfills

the requirements for applications such as Emergency Shutdown (ESD), Fire and Gas Protection (F&G),

Burner Management (BMS),High Integrity Pressure Protection (HIPPS), and Turbo Machinery Control (TMC).

The redundant high-availability architecture provides a flexible,robust, reliable,

and powerful solution that is ideal for clients looking to achieve environmental and safety excellence.

Tricon and Tricon CX  High-integrity +  high-availability system

The TriconTM high-integrity/high-availability system meets the needs of safety and critical

control applications in oil and gas, power, refining, chemicals, pharmaceutical, and biotech  industries.

It is based on industry-leading TMR technology, is easy to operate and maintain,  and provides a higher value of ownership.

company with the experience and track

record in safety and critical control with

more than 30 years of safety system

experience. It is also the only automation

company with more than 13.000 safety

systems installed in more than 80 countries

and operating for more than 1 billion hours.

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
