ICS Triplex T8431C Trusted CCoat TMR 4-20mA 40Ch AI Mod

Description

The ICS Triplex T8431C Trusted CCoat TMR 4-20mA 40Ch AI Mod is a high-reliability analog input module designed exclusively for the ICS Triplex Trusted system. As a member of the Trusted I/O family with Triple Modular Redundancy (TMR) technology, it provides fault-tolerant performance, ensuring continuous operation even if a single channel fails. Its core function is to collect analog signals from sensors measuring temperature, pressure, flow, and other process variables, then convert these signals to digital data for system processing and control.

Key technical specifications include a system power supply range of 20 to 32V DC, with a 24V DC input voltage. It operates in temperatures from -10 degrees Celsius to 60 degrees Celsius, and can be stored at temperatures from -20 degrees Celsius to 70 degrees Celsius, with a non-condensing humidity range of 10% to 90%. The module measures 96mm x 96mm x 98mm and weighs 0.5kg, featuring 40 independent analog input channels that accept 4-20mA current signals and 0-6V DC voltage signals. It offers an input current range of 0-22mA, a sample update time of 0.5ms, a resolution of 3.9 microamps (1/256mA), and a safety accuracy of ±1% of full scale. Ideal for high-safety industries, it is commonly used in nuclear power plant safety protection systems, petrochemical safety instrument systems, aerospace test systems, and rail transit control systems.
