Invensys TRICONEX | AO 3481 | AO3481 | Communication Module

Description

The Invensys TRICONEX AO3481 (AO 3481) Communication Module is part of the Triconex safety instrumented system (SIS) product line, designed for secure, reliable data communication in industrial safety applications. While specific technical data for this exact module is not available, it shares core design principles with other Triconex communication modules such as the 4351B. Key expected features include a redundant architecture and rigorous development standards to ensure high safety and system integrity, suitable for medium-risk industrial environments. It is likely to support multiple communication protocols, such as Ethernet and RS-232, with a maximum transmission rate of up to 10 Mbps and support for up to 32 device connections. Expected operating specifications include a 24 VDC power supply, an operating temperature range of -40 degrees Celsius to 70 degrees Celsius, and a 3U rack-mount form factor weighing approximately 2 kg. Like other Triconex modules, it is anticipated to meet global safety certifications including IEC 61508 SIL 2, ATEX, FM, and CSA, making it ideal for integration into fault-tolerant industrial control systems where uninterrupted communication and safety compliance are critical.
