T8403C ICS Triplex Trusted CCoat TMR 24V 40Ch DI Module

Description

The T8403C ICS Triplex Trusted CCoat TMR 24V 40Ch DI Module is a high-reliability digital input module built for critical industrial applications. It features a Triple Modular Redundancy (TMR) architecture, which delivers exceptional fault tolerance and system stability by replicating core functions across three independent channels. Equipped with comprehensive automatic diagnostic and self-test capabilities, the module continuously monitors its own status and performance in real time, enabling proactive detection of issues to maintain uninterrupted operation.

Key technical specifications include a 24V DC power supply, an input voltage range of 18V DC to 30V DC, maximum input current of 2.5A, and power consumption of 20W. The module has physical dimensions of 229mm x 81mm x 35mm and weighs 1.2kg, with an operating temperature range of -40 degrees Celsius to 85 degrees Celsius and an IP67 protection rating for durability in harsh environments. It supports 40 TMR digital input channels, each with selectable line monitoring to detect open and short circuit wiring faults. Additional features include a 2500V pulse-resistant optical/electrical isolation barrier, on-board Sequence of Events (SOE) reporting with 1 millisecond resolution, configurable 50/60Hz digital filtering to eliminate field-induced noise, and support for online hot-swapping via dedicated slots.
