ICS Triplex T8403C – Product Brief & Technical Specifications
Product Brief
ICS Triplex T8403C is a high-performance 8-channel digital input module designed for Triconex triple modular redundant (TMR) safety instrumented systems (SIS) and emergency shutdown (ESD) systems. As a core component of industrial safety automation solutions, it is engineered to collect and transmit digital input signals in hazardous and critical industrial environments with high reliability and anti-interference performance, complying with international functional safety standards. It is widely applied in petrochemical, oil and gas, power generation, and other process industries that require SIL-level safety guarantees, and is fully compatible with ICS Triplex Triconex TMR system architecture to ensure continuous and stable data acquisition for industrial control systems.

Technical Specifications
Brand & Model: The module is produced by ICS Triplex (a Honeywell brand specializing in industrial safety automation), with the official model T8403C.
Dimensions & Weight: The T8403C adopts the standard modular design of ICS Triplex Triconex systems, with an overall width of 31.75 mm (1.25 inches), a height of 254.0 mm (10.0 inches), and a depth of 165.1 mm (6.5 inches); the net weight of the module is approximately 0.227 kg (0.5 pounds), the lightweight design is suitable for dense cabinet installation and on-site maintenance operations.
Input & Output: This module is a dedicated digital input device without any output channels. It is configured with 8 independent digital input channels, all supporting 24V DC signal input, and the applicable input voltage range is 18-32V DC to adapt to the voltage fluctuation of industrial on-site power supplies. The channels support both sinking and sourcing signal types, and each channel is equipped with optoelectronic isolation technology, with channel-to-channel isolation and channel-to-system backplane isolation to avoid signal crosstalk and external interference from affecting the system.
Key Features
The T8403C has obtained SIL 3 functional safety certification in accordance with IEC 61508 standard, and has TÜV certification, meeting the safety requirements of high-risk industrial processes; it supports hot swap function, which allows the module to be replaced online without shutting down the TMR system, effectively reducing industrial production downtime; each input channel is equipped with an independent LED status indicator, which can visually display the on/off state of the channel signal and facilitate on-site fault diagnosis and maintenance; it is fully integrated with the Triconex TMR redundant control system, with built-in fault detection and self-diagnosis functions, which can automatically report module hardware and signal abnormalities to the upper system; it has excellent EMC/EMI anti-interference performance, complying with industrial electromagnetic compatibility standards, and can work stably in harsh industrial environments with strong electromagnetic interference; the operating temperature range is -40°C to +70°C, adapting to the temperature changes of different industrial sites; the module uses industrial-grade high-quality components, with high mechanical and electrical stability, and a long service life to meet the long-term continuous operation requirements of industrial systems.
