T8431 Trustworthy TMR 24VDC Digital Output Module

product description：

ICS TRIPLEX T8431 ROCKWELL Trusted TMR Module.The ICS Triplex T8110B is a Trustworthy TMR (Triple Modular Redundant) Processor module. It is a part of a robust, user-configurable system that provides overall system control, monitoring facilities, and process input and output data from various analog and digital input/output (I/O) modules through the Trusted TMR inter-module communication.ICS Triplex T8431

The Trusted® Processor is the main processing component in a Trusted System. It is a powerful, user-configurable module providing overall system control and monitoring facilities and processes input and output data received from a variety of analogue and digital Input / Output (I/O) modules across a Trusted TMR Inter-Module Communications Bus. The range of applications for the Trusted TMR Processor vary in integrity level and include fire and gas control, emergency shutdown, monitoring and control, and turbine control.

Functional Features
High Reliability: Utilizing the TMR architecture and fault-tolerant design, it is suitable for harsh industrial environments and can withstand high and low temperatures, vibrations, etc. Even if some circuits fail, the system can still operate normally.
High Precision Output: The output signal is precise and reliable, capable of meeting applications with high control accuracy requirements.
Automatic Diagnosis and Monitoring: It has comprehensive, automatic diagnosis and self-testing functions. It can automatically monitor the circuits, detect open-circuit and short-circuit faults in the on-site wiring and load equipment, and also provides a board-level event sequence (SOE) report with a resolution of 1ms.
Convenient Maintenance: Modules can be replaced online through hot swapping. The modular design makes installation and maintenance easy.
Electrical Isolation: It has a 2500V pulse tolerance / current isolation barrier, enhancing the module’s anti-interference ability and safety.

Technical Specifications
Power supply voltage range: The system’s power supply voltage range is 20 to 32V DC, the working output/fault voltage range is 18 to 32V DC, the output voltage measurement range is 0 to 32V DC, and the maximum tolerated voltage is -1 to 40V DC.
Output channels: There are 40 independent output channels, which can simultaneously control 40 different devices or loads. They are divided into 8 independent power groups, and each power group has 5 working outputs.
Output current: The rated output current (continuous) for each power group and each channel is 2A, limited to 8A for each power group, and the minimum on-state load current is 50mA.
Resistance characteristics: The resistance in the output-off state (effective leakage) is 33Ω, and the output-on resistance is 0.6Ω.
Capacitors: The capacitance range of the pre-released version 3.5 is 30-55uF, and in version 3.5, it is at least 2800uF at 2A.
Short-circuit protection: It has an electronic short-circuit protection function. When a short circuit occurs in the output, the module will automatically protect itself to prevent damage to the module or other equipment due to the short circuit.
Channel-to-channel crosstalk: The crosstalk between channels is limited to below -40dB, ensuring the independence of signal transmission between each channel and reducing mutual interference.
