Expand Chassis: The layout is similar to the main Chassis, but provides 8 logical slots for I/O modules; The length of the I/O bus cable is usually up to 100 feet (30 meters), and can reach up to 1000 feet (300 meters) in restricted applications. The address needs to be between 2-15 and unique, requiring two power modules connected to channels A, B, and C through a triple I/O bus cable.
RXM Chassis: Used in scenarios where the total length of I/O bus cables exceeds 100 feet (30 meters), with addresses 2-15 and unique; An RXM Chassis needs to be located within 100 feet (30 meters) of the main Chassis, with built-in main RXM module groups (usually supporting 3 groups), each group can support 3 remote sites, with each site up to 7.5 miles (12 kilometers) away from the main site. Remote sites require RXM Chassis and remote RXM module groups, with the main and remote RXM module groups connected by 6 fiber optic cables; Provide 6 I/O module logic slots and 1 blank slot, requiring two power modules that can be connected to the local expansion Chassis via I/O bus cables.
Core hardware component specifications
Power module: each Chassis is equipped with two, and any module can operate under full load and rated temperature, supporting online replacement; Convert the line power supply to a DC power supply suitable for the Tricon module, with an input of at least 240 watts per power module; The alarm contact will activate when the module is missing, there is a conflict between hardware and control program logic configuration, the module is faulty, the main processor detects a system fault, the main power supply of the power module is faulty, or there is a warning of "low battery" or "over temperature" in the power module; There are multiple models available, such as 8310 (120 VAC/VDC), 8311 (24 VDC), 8312 (230 VAC), with an output power of 175 watts (at 140 ° F/60 ° C), an output voltage of 6.5 VDC ± 1%, a maximum output current of 27 A (in 140 ° F/60 ° C environment), input and output isolation>1000 VAC or 1500 VDC, and an over temperature sensor triggered when the internal temperature is>181 ° F (83 ° C), usually corresponding to an ambient temperature of 140 ° F (60 ° C) or above.
Main processor module (Model 3008): Used in Tricon v9.6 and above systems, each system requires 3 main Chassis modules, which independently communicate with the I/O subsystem and execute user control programs; Includes Motorola MPC860 32-bit 50 MHz microprocessor, 16 MB DRAM (without battery backup), 32 KB SRAM (battery backup), 6 MB Flash PROM; TriBus communication speed of 25 Mbps, 32-bit CRC protection, 32-bit DMA and complete isolation; The I/O bus and communication bus processors are Motorola MPC860 32-bit 50 MHz; Equipped with multiple status indicator lights such as PASS, FAULT, and ACTION; Support sequence of events (SOE) and time synchronization, protect user programs and maintain variable integrity for at least 6 months during power outages, powered by dual power modules and main Chassis power rails.
Communication module: Multiple types meet different communication needs, such as the Tricon Communication Module (TCM) that supports communication with Modbus devices TriStation PC、 Communication between network printers, other Tricon controllers, and Ethernet devices, including 4 serial ports, 2 network ports, and 1 debugging port. A single system can support up to 4 ports and should be located in two logical slots; Enhanced Intelligent Communication Module (EICM) supports RS-232/422/485 serial communication, including 4 serial ports and 1 parallel port. A single system can support up to 2 ports, which need to be located in one logical slot; The Network Communication Module (NCM) supports Ethernet (802.3) communication, including 2 BNC interfaces and 1 RS-232 serial port, supports OPC Server and TSAA protocols, and NCMG supports GPS time synchronization; The Safety Manager Module (SMM) connects Tricon to Honeywell TDC 3000 UCN; Hiway interface module (HIM) connects Tricon with Honeywell TDC 3000 Hiway gateway and LCN; Advanced Communication Module (ACM) connects Tricon with Foxboro I/A Series DCS.
Remote Expansion Module (RXM): Supports I/O modules located several kilometers away from the main Chassis, consisting of three identical modules, serving as relays and extenders for the Tricon I/O bus, providing ground loop isolation; There are multimode fiber (4200-3 main, 4201-3 remote, maximum distance 1.2 miles/2 kilometers) and single-mode fiber (4210-3 main, 4211-3 remote, maximum distance 7.5 miles/12 kilometers) models, with a communication speed of 375 kbps and indicator lights such as PASS, FAULT, and ACTION.

On site terminal options
Terminal product type
External Terminal Panel (ETP): a passive printed circuit board that facilitates on-site wiring, transmits signals between the site and I/O modules, supports I/O module replacement without interfering with on-site wiring; The on-site signals can be collected in a separate enclosure up to 99 feet (30 meters) away from Tricon; The standard panel includes terminal blocks, resistors, fuses, and other components, suitable for lines 24-12 (0.3-2.1mm ²), with some having current limiting resistors or fuses with fuse indication; There are also basic panels (including connectors and terminal blocks only, users need to equip other components themselves), hazardous area (non flammable) panels (suitable for Zone 2, Class 1, Division 2, certified by T Ü V), panels with intermediate relays (suitable for load current>2A or voltage>115 VAC scenarios), digital input bypass panels (32 pre wired switches, including master key switch and redundant 24 VDC power terminals), panels with signal conditioners (supporting RTD, thermocouple, 4-20 mA transmitter, 16 points/panel, compatible with 1-5V output signal conditioners) and other types.
