ICS TriplexT8403 Core Function
Advanced Fault Isolation and Signal Integrity
The module employs 50 V reinforced continuous isolation and 250 V basic fault isolation, rigorously tested at 2,436 Vdc for 60 seconds to withstand transient surges in harsh electrical environments. Its input impedance of 5 kΩ and configurable voltage thresholds (-6 to +36 Vdc) ensure accurate signal interpretation across diverse field devices, with a safety accuracy margin of ±0.5 Vdc.
Configurable Threshold Flexibility
Unlike standard digital input modules, the T8403 allows per-channel threshold customization, enabling tailored voltage trip points (e.g., 8 Vdc for low-level signals or 28 Vdc for noise-prone installations). This adaptability supports mixed-device integration within a single module.
Certified Safety Compliance
Certified under hardware release I37 with firmware Build 037, the T8403 meets TÜV Industrie Service standards for safety-critical applications, including SIL 3 compliance. Its redundant chassis integration aligns with IEC 61131 toolset requirements for fail-safe system configurations.
