Ics Triplex T8850 Expander Interface Module

Description

The ICS Triplex T8850 Expander Interface Module is a triple modular redundant (TMR) architecture-based expander interface component designed to boost industrial control system reliability and safety. Built with redundant hardware and software, it delivers enhanced fault tolerance for critical automation applications. Powered by a 32-bit RISC processor, the module offers high-speed scanning and robust processing capabilities to support demanding system operations.

Key technical specifications include 24V DC input and output voltages, with flexible power supply options: 21 to 28VAC at 50 to 60Hz when connected to P24, N24 terminals, and 85 to 260VAC at 50 to 60Hz when connected to L, N terminals. It features a Modbus TCP/IP communication interface for seamless integration with networked control systems. The module supports a wide operating temperature range of -40 degrees Celsius to 70 degrees Celsius, making it suitable for harsh industrial environments. Designed for 19-inch rack mounting, it has a weight of 20kg and is installed in the left processor slot of an expander chassis to provide a dedicated interface between expander and controller chassis, enabling scalable system expansion while maintaining TMR-level safety and reliability.
