Overview
The T8403 Digital Input Module is an integral component of the ICS Triplex Trusted system. It provides Triple Modular Redundancy (TMR), ensuring continuous operation even if one module fails. Additionally, it delivers robust digital input monitoring for demanding industrial environments. This module supports precise event recording and rapid signal processing, which makes it suitable for critical control applications.
Key Features
- Triple Modular Redundancy (TMR): Enhances reliability by maintaining operation despite a single module failure.
- High-Resolution Event Recording: Sequence of Events (SOE) with 1 ms resolution and ±10 ms timestamp accuracy.
- Flexible Input Configuration: Supports 40 digital inputs with configurable thresholds and high safety accuracy (0.5 Vdc).
- Robust Electrical Design: Operates with a backplane supply of 20–32 Vdc and maximum dissipation of 29 W.
- Strong Environmental Compliance: Withstands vibration, shock, and extreme temperatures, suitable for industrial control rooms.
- EMC and Surge Immunity: Certified for radiated and conducted emissions (CISPR 11 Class A), ESD protection, and high-voltage surge and transient immunity.
