        Features:

        • Adds Tricon I/O and communication-module capacity beyond the main chassis.
        • Provides dual connector sets for the triplicated A, B and C expansion buses.
        • Accepts the documented Tricon power-module options and keyed module slots.
        The current configuration is the 8111 local I/O Expansion Chassis, distinct from the main and remote-expansion chassis models.

        It extends the controller backplane through redundant triplicated serial paths while sharing the system's processor supervision.

        A valid build requires correct chassis addressing, cable sets, power budget, grounding and permitted module placement.

        Availability is subject to Apter Power inventory and sourcing confirmation.
        Verified resources for Triconex 8111:Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
        • Adds local I/O capacity to a Tricon safety system within the documented cable reach.
        • Houses additional analog, digital and communication modules for large projects.
        • Supports expansion during system retrofit while the main processor chassis remains unchanged.
        • The chassis must be mechanically secured with clearance for module insertion and cabinet airflow.
        • Triplicated expansion-bus cables connect channels A, B and C between the main and expansion backplanes.
        • Protective earth, logic power and the chassis address are completed before modules are commissioned.
        • Chassis power planning assumes the documented worst-case ambient condition of 60 °C.
        • Installed modules require a clean control enclosure with non-condensing humidity.
        • Cooling clearance must be maintained around densely populated racks and their power supplies.
        • The triplicated expansion backplane follows the documented Tricon I/O and communication-bus architecture.
        • Chassis construction and module keying are part of the approved Tricon system hardware arrangement.
        • System certification remains dependent on the complete installed controller configuration rather than the empty rack alone.
        Description
        Triconex 8111 is the standard expansion chassis used to extend a Tricon controller beyond the main chassis. Its backplane distributes logic power and the triplicated I/O bus to installed modules. The chassis extends local I/O through three RS-485 bus channels, with duplicated connector sets supporting the triplicated A, B and C paths.

        Six RS-485 expansion-bus ports provide two connector sets for channels A, B and C. This arrangement carries voted I/O traffic between expansion hardware and the three main processors at the specified bus rate. Separate I/O and communication buses carry deterministic module traffic while two power positions allow a redundant chassis supply arrangement.

        System design must account for cable-set type, chassis address, slot population, power-module capacity and communication-module placement. Grounding and airflow must be completed before any I/O module is energized. Hardware addressing, protective earth and cable-set selection establish the expansion position before any keyed I/O modules are installed.

        Technical notes
        8111 addressing, triplicated I/O-bus cabling and worst-case power loading must be verified before installed modules are energized.

        VIEW ALL FAQS
        What ordering detail identifies the intended configuration of 8111?
        The 8111 designation identifies the local expansion chassis; the main and remote chassis use different catalog numbers.
        Which companion hardware defines compatibility for 8111?
        Verify the main-chassis generation, expansion-cable set, address plan, power modules and intended slot population.
        Where does 8111 sit in the documented control architecture?
        It increases available I/O and communication capacity while retaining the triplicated controller bus.
        Who can verify condition and lead time for 8111?
        Apter Power can review the rack identity and provide current condition, included-hardware and delivery information.
        What must remain unchanged during an exchange of 8111?
