Product Overview
The ICS Triplex T8161B Digital Input Module is a core component developed by ICS Triplex, a brand under Rockwell Automation, specifically for safety-critical industrial control systems. It focuses on meeting the high reliability and safety requirements of process industries, and is suitable for scenarios demanding strict fault tolerance, such as petrochemicals, power energy, rail transit, and nuclear industry.Adopting a redundant design architecture, the module is compatible with Triplex Tricon and TriconEX safety control systems. It enables accurate collection, real-time transmission, and safety monitoring of on-site discrete digital signals, providing underlying data support for the continuous and stable operation of industrial processes and helping users achieve SIL 3 safety integrity level certification.
Core Features
- Safety Redundant Design: Dual independent signal acquisition channels and redundant communication interfaces, supporting fault self-diagnosis and automatic switching to ensure uninterrupted system operation under single fault conditions, complying with international safety standards such as EN 50159 and IEC 61508.
- Highly Adaptable Signal Acquisition: Supports 16-channel discrete digital input, compatible with 24VDC/48VDC standard industrial signals, with an input response time as low as 1ms, adapting to the signal output requirements of different on-site equipment.
- Anti-interference and Stability: Adopts photoelectric isolation technology and EMC electromagnetic compatibility design, capable of resisting electromagnetic interference, voltage fluctuations and other harsh environmental impacts in industrial sites, with an operating temperature range of -40℃~70℃ to adapt to extreme working conditions.
Easy Integration and Maintenance: Modular plug-and-play design supporting hot-swapping, allowing installation, replacement or maintenance without shutting down the system; equipped with intuitive LED status indicators to provide real-time feedback on channel working status and fault information, simplifying the operation and maintenance process.
