ICS Triplex T8461C – Product Brief & Technical Specifications
Product Brief
ICS Triplex T8461C is a high-performance 8-channel digital output module exclusively developed for the Triconex triple modular redundant (TMR) safety instrumented system (SIS) and emergency shutdown (ESD) system. As a core output component of industrial safety automation solutions, it is dedicated to converting the control signals of the TMR system into actionable digital output signals in critical and hazardous industrial environments, with ultra-high reliability and stable signal transmission performance. Compliant with international functional safety standards, it is widely used in petrochemical, oil and gas, power generation, metallurgy and other process industries with strict SIL-level safety requirements, and is fully compatible with the ICS Triplex Triconex TMR system architecture, ensuring accurate and timely execution of system control commands to safeguard the safe and continuous operation of industrial production processes.

Technical Specifications
Brand & Model: The module is manufactured by ICS Triplex, a professional brand of Honeywell focusing on industrial safety automation, with the official model number T8461C.
Dimensions & Weight: The T8461C adopts the standard modular structural design of the ICS Triplex Triconex product series, which is consistent with the series modules in installation size for cabinet layout standardization. Its overall width is 31.75 mm (1.25 inches), height is 254.0 mm (10.0 inches), and depth is 165.1 mm (6.5 inches); the net weight of the module is approximately 0.227 kg (0.5 pounds). The lightweight and compact design is suitable for dense installation in industrial control cabinets, and also facilitates on-site disassembly, assembly and maintenance operations.
Input & Output: This module is a dedicated digital output device without any input channels, configured with 8 independent and isolated digital output channels. It supports 24V DC standard industrial signal output, and the applicable working voltage range is 18-32V DC, which can adapt to the normal voltage fluctuation of on-site power supplies and ensure stable output under different power supply conditions. All channels are designed with high-performance photoelectric isolation technology, realizing complete electrical isolation between channels and between channels and the system backplane, which can effectively prevent external electrical interference and signal crosstalk from affecting the output accuracy and system safety, and also avoid the damage of on-site load faults to the core control system.
Key Features
The T8461C has obtained SIL 3 functional safety certification in accordance with the IEC 61508 international standard, and has passed TÜV authoritative certification, fully meeting the safety operation requirements of high-risk industrial process control; it supports the hot swap function, which allows the module to be replaced online without shutting down the Triconex TMR system, effectively eliminating the production downtime caused by module maintenance and replacement and ensuring the continuous operation of the industrial system; each output channel is equipped with an independent LED status indicator light, which can visually and real-time display the on/off working state of the channel and the fault alarm status, greatly facilitating on-site staff to quickly locate channel faults and carry out maintenance; it is fully integrated with the Triconex TMR redundant control system, with built-in real-time fault detection and self-diagnosis functions, which can automatically monitor the module’s hardware operating status and output signal abnormalities, and timely upload the fault information to the upper monitoring system to realize predictive maintenance; the module has excellent EMC/EMI anti-interference performance, complying with the international industrial electromagnetic compatibility standard, and can work stably in harsh industrial environments with strong electromagnetic interference, high dust and high humidity; it has a wide operating temperature range of -40°C to +70°C, adapting to the extreme temperature changes of different industrial sites such as cold regions, high-temperature workshops and outdoor control cabinets; it is equipped with an independent output short-circuit protection function for each channel, which can automatically cut off the output when the on-site load is short-circuited to protect the module and the system from damage, and resume normal work after the fault is removed; the whole module uses industrial-grade high-quality electronic components and precision structural parts, with high mechanical and electrical stability and long service life, meeting the long-term continuous operation requirements of industrial control systems for more than 10 years; it is designed in accordance with the universal installation standard of the Triconex system, with a plug-and-play structural design, which can be seamlessly connected to the Triconex system backplane, reducing the difficulty of on-site installation and commissioning.
