Beskrivelse
Product Overview
The ICS Triplex T8850 Expander Interface Module extends the I/O capacity of Trusted TMR systems without compromising safety integrity. It enables seamless communication between the TMR controller and remote expansion chassis, supporting distributed control architectures in large-scale process facilities. This module maintains SIL 3 compliance while delivering deterministic data exchange at 10 Mbps.
Core Functionality
The T8850 serves as the communication bridge between the Trusted TMR processor and expansion I/O racks. It operates on a 24 Vdc supply with typical current draw of 300 mA. The module transmits I/O data at 10 Mbps, ensuring synchronized operation across distributed chassis. 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.

Installation Guide
Install 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.
Engineering Advantages
The 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).
Technical FAQs
Q1: Can the T8850 connect to non-Trusted expansion chassis?
A1: No. The T8850 is exclusively compatible with Trusted TMR expansion chassis using the proprietary inter-module protocol.
Q2: How many expansion chassis does one T8850 support?
A2: One T8850 supports a single expansion chassis. For multiple racks, install one module per chassis.
Q3: Is the T8850 hot-swappable?
A3: Yes. In TMR configurations, individual modules can be replaced online. The remaining two modules sustain communication while the third is swapped.
