With 32 isolated input channels, the TRICONEX 3301 ensures comprehensive monitoring of industrial processes, making it essential for maintaining safety and operational integrity in environments where downtime or malfunction could lead to severe consequences.
As part of TRICONEX’s TMR (triple modular redundancy) architecture, the 3301 operates with three independent processing channels that continuously verify each other’s outputs, eliminating single points of failure. This design aligns with SIL 3 (IEC 61508) safety standards, ensuring compliance with rigorous industrial requirements. The module supports a wide range of input signals, including 24V DC logic, dry contacts, and high-speed pulses, making it versatile for diverse applications in oil and gas, chemical processing, power generation, and pharmaceuticals. Its robust construction and extended temperature range (-40°C to +70°C) further enhance its suitability for harsh industrial environments.
