The T8111C is an industrial automation module from the ICS Triplex brand. It belongs to the Triplex series and adopts a Triple Modular Redundancy (TMR) architecture, featuring high reliability and performance. It is mainly used for real-time monitoring and controlling the status and values of digital input signals. Its relevant parameters and characteristics are as follows:
- Architecture: Utilizes TMR architecture with fault-tolerant (3-2-0) operation capability, ensuring high availability and safety in critical applications.
- Programming language: Supports IEC 61131-3 programming languages, allowing users to develop and debug programs using standard programming languages or dedicated development tools.
- Signal acquisition: Typically equipped with high-resolution Analog-to-Digital Converters (ADCs) to ensure the accuracy and precision of digital signal acquisition. It supports various digital signal types such as switch states, pulse counts, and digital sensor outputs.
- Sampling rate: The sampling rate is configurable and can be adjusted according to application requirements to optimize system performance and response speed.
- Communication interface: Usually connects to control systems or monitoring systems via communication interfaces such as Ethernet, Modbus, and Profibus to realize real-time data transmission and sharing. It also has two configurable RS422/485 connections with 2 or 4 wires.
- Diagnostic function: Equipped with a front-panel RS232 serial diagnostic port with a serial data rate of 19.2 kbit/s, which is used for system monitoring, configuration, and programming. The module's real-time operating system automatically schedules hardware tests for microprocessors, memory management units, HIFT clocks, communication buses, etc. The test results are stored in logs for uploading to engineering workstations.
- Time synchronization: Supports IRIG-B002 and B122 time synchronization signals.
- Operating voltage: Usually 24V, but some data indicate 220V.
- Product certification: Certified to IEC 61508 SIL 3, and some mentions of CE certification.
- Structural form: Modular structure, weighing approximately 1.5kg.
