Additional Details

• The 2755-6 includes the following additional information based on its standard use and documentation:
• Function: Interfaces with field devices like switches, sensors, and transmitters to process digital input signals for safety applications such as emergency shutdown (ESD), fire and gas detection, and process monitoring. Ensures reliable signal acquisition within the TMR framework for fault-tolerant operation.
• Mounting: Installs in Tricon chassis (e.g., 8110 high-density or 8400 low-density) slots, interfacing with the system backplane; mechanically keyed for correct placement.
• Compatibility: Compatible with Tricon v9.6 and later systems; integrates with TriStation 1131 software for configuration, diagnostics, and monitoring. Works with other Tricon modules like 3008 Main Processors and 4119A communication modules.
• Configuration: Configurable via TriStation 1131 software; supports hot-swappable modules for maintenance without process interruption. Features channel-to-channel isolation to prevent signal interference.
• Certifications: Meets IEC 61508 SIL3, UL, CE, and Factory Mutual (FM) standards for Class I, Division 2 hazardous locations; complies with IEC 61131 environmental and EMC requirements.
