The Triconex Tricon Safety Instrumented System is designed to meet 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 the lowest total cost of ownership.

Models 3502E, 3503E, and 3505E can self-test to detect stuck-On conditions where the circuitry 

cannot tell whether a point has gone to the Off state. 

Since most safety systems are set up with a deenergize-to-trip capability, the ability to detect Off points is an important feature.

To test for stuck-On inputs, a switch within the input circuitry is closed to allow a zero input (Off) to be read by the optical isolation circuitry.

The last data reading is frozen in the I/O communication processor while the test is running.

Summary of Tricon

Components

Chassis

• Main Chassis—houses Main Processors, memory back-up batteries, communication modules and I/O modules.

• Expansion Chassis—for additional I/O modules up to 100 feet (30meters) away from the Main Chassis. In restricted applications,

operation up to 1,000 feet (300 meters) is supported.

• RXM Chassis—for I/O modules up to 7.5 miles (12 kilometers) away from the Main Chassis.

• Mechanical Keying—Each slot in the Tricon is mechanically keyed to correspond with a specific type of module. 

This prevents the installation of modules into improper slots.

Power Supply Modules

• Provide logic power to modules in the Main, Expansion or RXM

Chassis. Available in 24 VDC, 115 VAC and 230 VAC versions. The

power rating of each power supply is 175 watts at 140 ° F (60° C).

Main Processors

The Main Processors execute the system diagnostics and the user-written control program.

Communication Modules

• Tricon Communication Modules (TCM) support a number of Triconex protocols and applications and user-written applications 

on Ethernet (802.3) networks, including TriStation, Modbus TCP and OPC. 

It also supports RS-232 and RS-485 serial communication with Modbus devices, TriStation 1131. and GPS for time synchronization.

• Enhanced Intelligent

Communication Modules (EICM) support RS-232. RS-422 and RS-485 serial communication with Modbus devices and TriStation 1131.

• Network Communication Modules (NCM) support a number of Triconex protocols and applications and 

user-written applications on Ethernet (802.3) networks, including TriStation 1131.

• Safety Manager Modules (SMM) act as an interface between a Tricon controller and a Honeywell Universal Control Network (UCN),

one of three principal networks of the TDC-3000 DCS.

• Hiway Interface Modules (HIM) act as an interface between a Tricon controller and a 

Honeywell TDC-3000 Hiway Gateway and Local Control Network (LCN).

• Advanced Communication Modules (ACM) allow a Tricon controller to interface with 

a Foxboro Industria Automation (I/A) Series DCS and TriStation 1131.
