Description

ICS Triplex T8451 Triple Redundant Digital output module

Power supply voltage: The system power supply voltage range is 20 to 32V DC, the on-site voltage range is between 18 and 32V DC, the output voltage measurement range is from 0 to 32V DC, and it can withstand a maximum voltage of -1 to 40V DC.

Circuit type: It adopts a fault-tolerant design with a fully triple selectable circuit. There are three identical circuits working simultaneously inside the module to ensure correct and reliable output.
Number of channels: It has 40 independent channels for monitoring and output. The module is divided into 8 independent power groups, and each power group has 5 working outputs.

Output current: The rated output current for each channel of each power supply group is 2A, the total maximum output current is 8A, and the minimum open-state load current is 50mA.
Protection function: It features electronic short-circuit protection. When a short circuit occurs in the output, the module will automatically provide protection.
Channel crosstalk: The crosstalk between channels is limited to below -40 dB to ensure the independence of each channel.

Other features: This module provides on-board Event Sequence (SOE) reports with a resolution of 1 millisecond, in compliance with SIL 3 and TUV certifications of IEC 61508.

High reliability: It adopts triple Module Redundancy (TMR) technology, with three identical circuits working simultaneously inside. The output is determined through a majority voting system, which can effectively avoid single point of failure. Supports online hot replacement, allowing modules to be replaced without interrupting the system operation, ensuring continuous system operation. In addition, it also has an electronic short-circuit protection function, which can automatically protect itself when there is a short circuit in the output.

Strong signal processing capability: Supports multiple communication protocols such as Ethernet, Modbus TCP/IP, ensuring high-speed data transmission. It can quickly process and transmit digital signals and is suitable for scenarios with high requirements for signal processing speed and reliability, such as the oil and gas, chemical processing and other industries.

High adaptability: Supports integration with third-party software applications and tools, allowing users to customize and expand according to their specific needs. Programming can also be carried out using multiple programming languages such as ladder diagrams and function block diagrams, which is convenient for engineers with different technical backgrounds to use.

High safety: Compliant with SIL 3 and TUV certifications of IEC 61508, it ensures that the system operation meets strict safety standards and can be used in situations with extremely high safety requirements, such as nuclear power plant reactor protection systems, emergency shutdown systems, etc.
Strong durability: Specially designed for harsh environments, it can withstand extreme temperatures, shocks and vibrations, and can operate in an environment ranging from -40 ℃ to + 70℃, adapting to various complex industrial environments.

Convenient maintenance: The non-volatile memory of the module can store over 10,000 event logs with a resolution of 1ms, facilitating forensic analysis after a security incident occurs. The LCD on the front panel of some models can display the percentage of remaining contact life, which is convenient for users to understand the module status in time and carry out maintenance and care.
