Main Title: Triconex 8111 High Density Expansion Chassis for Tricon Systems

Product Overview

The Triconex 8111 is a high density expansion chassis for Tricon systems. Therefore, it expands I/O capacity beyond the main chassis limitations. In addition, this 8111 chassis features six RS-485 I/O expansion bus ports. As a result, it supports triplicated serial communications between multiple chassis. Moreover, the chassis construction uses black zinc-plated cold-rolled steel. Finally, the Triconex 8111 is designed for industrial safety applications.

I/O Expansion Bus Ports

The 8111 expansion chassis provides extensive communication connectivity. Specifically, six RS-485 I/O expansion bus ports sit at the top left corner. Furthermore, these ports are arranged in two sets for channels A, B, and C. Also, this provides two triplicated serial communications paths between chassis. Notably, the Triconex 8111 requires one cable set for each expansion chassis. Therefore, the system maintains redundancy for critical data paths.

Communication Speed and Data Transfer

The 8111 expansion chassis transfers data at reliable industrial speeds. Specifically, the triplicated I/O bus transfers data at 375 kilobits per second. Furthermore, this bus runs between I/O modules and the main processors. Also, the communication bus between main processors and communication modules runs at 2 megabits per second. Notably, the Triconex 8111 supports real-time control data exchange. Therefore, system performance meets demanding process control requirements.

Cable Specifications

The 8111 expansion chassis requires specific cable sets for operation. Specifically, the standard cable set (model 9000) measures 6 feet in length. Furthermore, longer cables are available if your installation needs them. Also, one cable set is required for the RXM chassis with primary RXM module set. Notably, the Triconex 8111 uses standard RS-485 cabling for expansion. Therefore, you can order custom lengths for distributed system layouts.

Keyswitch Modes Overview

The 8111 chassis works with Tricon system keyswitch modes. Specifically, the chassis supports the RUN mode for normal operation. Furthermore, RUN executes the previously-loaded control program without modification. Also, attempts to modify program variables are rejected in RUN mode. Notably, gated access functions can enable external host writes during designated windows. Therefore, the Triconex 8111 supports secure system operation.

PROGRAM Mode Functionality

The 8111 expansion chassis operates in PROGRAM mode for loading. Specifically, PROGRAM mode allows program loading and checkout activities. Furthermore, it enables control of the Tricon system from the TriStation platform. Also, Download All and Download Change commands are permitted in this mode. Notably, PROGRAM mode allows writes to program variables by external hosts. Therefore, the Triconex 8111 facilitates system configuration and testing.

STOP Mode Behavior

The 8111 chassis supports STOP mode for maintenance activities. Specifically, STOP mode stops reading inputs from field devices. Furthermore, it forces non-retentive digital and analog outputs to 0. Also, the control program halts execution in STOP mode. Notably, retentive outputs retain their previous values during STOP mode. Therefore, the Triconex 8111 allows safe process equipment servicing.

REMOTE Mode Features

The 8111 expansion chassis operates in REMOTE mode for remote access. Specifically, REMOTE mode allows writes to program variables by TriStation. Furthermore, external hosts can also write program variables in this mode. Also, Download All and Download Change by TriStation are not allowed. Notably, modification of program logic is not permitted in REMOTE mode. Therefore, the Triconex 8111 supports remote monitoring without logic changes.

Chassis Dimensions

The 8111 expansion chassis requires significant cabinet space. Specifically, overall width measures 19 inches (48.3 cm) for standard racks. Furthermore, height is 22.75 inches (57.8 cm) for vertical mounting. Also, depth measures 17.75 inches (45.1 cm) for cable clearance. Notably, the Triconex 8111 fits standard 19-inch industrial cabinets. Therefore, plan adequate space for installation and ventilation.

Chassis Fabrication and Material

The 8111 expansion chassis uses durable materials for industrial environments. Specifically, chassis fabrication uses black zinc-plated cold-rolled steel. Furthermore, the steel is welded for structural integrity and strength. Also, the black zinc plating provides corrosion resistance. Notably, the Triconex 8111 withstands harsh factory conditions. Therefore, this chassis provides long-term reliability in critical applications.

Chassis Weight Specifications

The 8111 expansion chassis has substantial weight for stability. Specifically, the main or expansion chassis weighs 54.0 lbs (24.5 kg). Furthermore, the power module adds 7.2 lbs (3.3 kg) when installed. Also, each main processor weighs 4.7 lbs (2.1 kg) for reference. Notably, I/O modules weigh between 4.7 and 6.0 lbs (2.1 to 2.7 kg). Therefore, the Triconex 8111 requires sturdy mounting and support.

Module Weights for Planning

The 8111 expansion chassis accommodates various module types. Specifically, communication modules weigh 5.0 lbs (2.3 kg) each. Furthermore, 16-point termination panels weigh only 0.09 lbs (0.04 kg). Also, 32-point termination panels weigh 2.1 lbs (0.95 kg). Notably, the Triconex 8111 supports high density I/O configurations. Therefore, calculate total weight before final cabinet selection.

Installation Guidelines

First, mount the Triconex 8111 in a standard 19-inch industrial cabinet. Second, secure the 54 lb chassis using appropriate mounting hardware. Third, connect RS-485 cables to the six I/O expansion bus ports. Fourth, install model 9000 cable sets (6 ft standard) between chassis. Fifth, verify triplicated communication paths for channels A, B, and C. Note, the 8111 requires one cable set for each expansion chassis.
