Description

Description

The ICS TRIPLEX T8461C Trusted TMR Digital Output Module is a high-reliability output solution designed for safety-critical industrial control systems. Operating at 24 Vdc and 48 Vdc, this module is part of the Trusted™ Triple Modular Redundancy (TMR) platform, ensuring dependable and fault-tolerant digital output control in demanding environments.

The T8461C provides 40 digital output channels, enabling direct control of field devices such as actuators, relays, and valves. Each output channel uses a triple-redundant architecture, allowing the system to continue operating correctly even if a single path or component fails. This design significantly improves system availability and operational safety.

Advanced automatic diagnostics and continuous self-testing help detect wiring issues such as open circuits, short circuits, and load faults. Built-in overcurrent protection safeguards connected devices, while onboard Sequence of Events (SOE) recording with 1 ms resolution supports precise event analysis and troubleshooting. Fully compatible with Trusted™ systems and compliant with safety standards, the ICS TRIPLEX T8461C is ideal for industries such as oil & gas, power generation, and chemical processing.
