ICS Triplex T8151B Trusted Communications Interface Module

Overview

The ICS Triplex T8151B is a high-performance Trusted Communications Interface (CI) module designed to offload communication tasks from a Triple Modular Redundant (TMR) processor. It supports multiple communication protocols, offering secure and reliable data exchange for ICS Triplex safety-critical control systems. The module allows a Trusted System to incorporate up to four communication interfaces for scalable network connectivity.

Key Features

Dual Ethernet and Serial Ports: Two 10/100BaseT Ethernet ports and four serial ports support RS-232, RS-422, and RS-485 connections.
Communication Protocols: Supports Modbus RTU, Open Modbus TCP, Trusted Peer-to-Peer, and Trusted Enhanced Peer-to-Peer protocols.
SOE Buffer Support: Stores up to 4000 Sequence of Events (SOE) records for event logging and analysis.
Diagnostics and Indicators: Front-panel serial diagnostic port, fault, and status indicators simplify troubleshooting and system monitoring.
User-Configurable: Adapts to different network requirements and media types, providing flexible connectivity in industrial applications.
Integration: Designed for installation in T8100 and T8300 I/O module slots with Trusted TMR processors.
