Tricon CX is a flexible SIL3 platform designed for

the protection and mitigation of risks in high-hazard

industries where safe and continuous operation are

imperative. Tricon CX is capable of handling input/

output (I/O) counts of all sizes, from as little as

16 I/O channels in a single system to in excess

of 750,000 I/O channels when deployed across 254

nodes. Systems can be centralized in one location,

as well as distributed across multiple assets. All

modules are fault tolerant and continue to operate

even under fault conditions.

The simple mechanical design of Tricon CX makes

it quick and easy to design, install, operate and

maintain. Only three components are required to

configure a Tricon CX system — the chassis, the

modules, and the connectors.

Modules and connectors are separate, so modules

can be replaced online without disturbing the I/O

modules or wiring.

Chassis are designed for panel mounting or 19”

mounting. No swing frames are required. Front

access only is required — there is no need for rear

access to any of the Tricon CX racks, modules,

or connectors.

I/O modules and connector boards are keyed to

prevent incorrect insertion.

Termination panels are supported and can be used

with Tricon CX for maximum interoperability.

The integrated 24 Vdc power management and

fusing simplifies power distribution, requiring less

wiring, less engineering, less testing, and lower

overall cost.
