8110 Main Controller Chassis Invensys

Overview

Configured for triplicated I/O bus communication and controller module mounting in the Tricon fault-tolerant controller platform, the Invensys 8110 (8110 Main Controller Chassis) provides the mechanical and backplane interface for Tricon controller hardware. It uses three isolated RS-485 channels at 375 kbit/s and provides six backplane bus connectors.

Hardware Specifications

TMR Backplane and Safety Control Architecture

The 8110 chassis supports a triple modular redundant controller arrangement. Three isolated RS-485 I/O bus channels provide triplicated communication paths between the controller hardware and associated I/O architecture.

The backplane provides six bus connectors for module and expansion connections. Mechanically keyed slot guides control module positioning and reduce the possibility of incorrect module placement.

The controller keyswitch provides RUN, PROGRAM, STOP, and REMOTE selections. Therefore, the physical switch position determines the available controller operating mode and must match the system commissioning procedure.

The supplied data specifies a 2 Mbit/s communication bus for the module link. TriStation 1131 provides the stated engineering and configuration environment.

Frequently Asked Questions

Q: Does the 8110 chassis provide isolated I/O communication channels?

A: Yes. The supplied specifications identify three isolated RS-485 I/O bus channels operating at 375 kbit/s.

Q: How many backplane bus connectors are specified for the 8110?

A: The supplied data specifies six backplane bus connectors.

Q: Does the chassis itself specify power consumption?

A: No. The supplied data does not provide a power consumption value for the 8110 chassis. Do not substitute a value from another Tricon chassis or controller assembly.

Field Installation Guidelines

Install the 8110 in the specified 19-inch rack arrangement and maintain sufficient clearance for the stated 45.1 cm enclosure depth. Confirm the mechanical mounting points before securing the welded steel chassis.

Verify all module positions against the system hardware configuration before installation. Use the mechanically keyed slot guides as the physical reference for module placement.

Route RS-485 and other communication wiring separately from high-voltage power conductors where practical. Avoid unnecessary parallel routing with switching power circuits and high-current conductors.

Terminate cable shields according to the installed Tricon system wiring specification and site grounding practice. Avoid creating unintended ground paths through shield connections.

Before energizing the controller assembly, verify connector seating, module orientation, backplane connections, and keyswitch position. Confirm the installed hardware configuration in TriStation 1131 before placing the controller into the required operating state.

Do not infer operating temperature, power consumption, or weight from another Tricon chassis model. These values require confirmation from the applicable hardware documentation or nameplate.
