Its robust design accommodates up to 95% non-condensing humidity and a wide storage temperature range of -40°C to +85°C, making it suitable for both indoor and sheltered outdoor installations.\u003c\/p\u003e\n\n\u003ch2 style=\"color: #0055A4;\"\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse; font-size:14px;\"\u003e\n  \u003ctr style=\"background:#f2f2f2;\"\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e\u003cstrong\u003eValue\u003c\/strong\u003e\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eModel\u003c\/td\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eT8850\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f9f9f9;\"\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eType\u003c\/td\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eExpander Interface Module\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eSystem Compatibility\u003c\/td\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eTrusted TMR (Triple Modular Redundant)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f9f9f9;\"\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eCommunication Speed\u003c\/td\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e10 Mbps\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eOperating Voltage\u003c\/td\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e24 Vdc\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f9f9f9;\"\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eCurrent Consumption\u003c\/td\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e300 mA (typical)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eOperating Temperature\u003c\/td\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e0°C to +60°C (32°F to 140°F)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f9f9f9;\"\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eStorage Temperature\u003c\/td\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e-40°C to +85°C (-40°F to 185°F)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eHumidity\u003c\/td\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e5% to 95% (non-condensing)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f9f9f9;\"\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eDimensions (W x H x D)\u003c\/td\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e60 x 170 x 105 mm\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eWeight\u003c\/td\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e0.8 kg\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f9f9f9;\"\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eMTBF\u003c\/td\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e\u0026gt;500,000 hours\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eStandards Compliance\u003c\/td\u003e\n    \u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eIEC 61508 SIL 3, ATEX, FM, CE, UL\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2 style=\"color: #0055A4;\"\u003eInstallation Guide\u003c\/h2\u003e\n\u003cp\u003eInstall the T8850 in a dedicated slot within the Trusted TMR expansion chassis. Ensure the backplane connectors are free from debris before insertion. Secure the module with the provided retaining screws – torque to 0.4 N.m. Maintain at least 20 mm clearance around the module for adequate airflow. Connect the expansion cable to the front-panel interface port, verifying proper locking of the connector. For TMR configurations, install three T8850 modules to maintain full redundancy across the expansion link.\u003c\/p\u003e\n\n\u003ch2 style=\"color: #0055A4;\"\u003eEngineering Advantages\u003c\/h2\u003e\n\u003cp\u003eThe T8850 delivers SIL 3-rated expansion connectivity with an MTBF exceeding 500,000 hours, minimizing unplanned downtime. Its wide storage temperature tolerance (-40°C to +85°C) protects the module during transport and storage in extreme climates. The 10 Mbps communication speed ensures I\/O updates occur within the Trusted system's deterministic scan cycle. ATEX, FM, CE, and UL certifications qualify the module for installation in hazardous area classifications (Zone 2 \/ Class I, Div 2).\u003c\/p\u003e\n\n\u003ch2 style=\"color: #0055A4;\"\u003eTechnical FAQs\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ1: Can the T8850 connect to non-Trusted expansion chassis?\u003c\/strong\u003e\u003cbr\u003e\nA1: No. The T8850 is exclusively compatible with Trusted TMR expansion chassis using the proprietary inter-module protocol.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: How many expansion chassis does one T8850 support?\u003c\/strong\u003e\u003cbr\u003e\nA2: One T8850 supports a single expansion chassis.
