Invensys TRICONEX 4351B Tricon Communication Module

Description

The Invensys TRICONEX 4351B Tricon Communication Module is a high-performance, reliable communication component designed exclusively for Triconex Safety Instrumented Systems (SIS), suitable for a wide range of critical SIS applications across industries including petrochemical, oil and gas, power generation, chemical processing, and rail transit. It operates on an input voltage of 24V DC (±10%), with configurable output options of 8 or 16 relay outputs, and features 16 digital outputs each capable of driving up to 1A at 24V DC, with electrical isolation between outputs and the I/O section to prevent damage from electrical transients and interference.

Key technical specifications include an operating temperature range of -40 degrees Celsius to 70 degrees Celsius, a storage temperature range of -40 degrees Celsius to 85 degrees Celsius, adaptive 10/100Mbps communication speed, 500VDC isolation voltage, and maximum power consumption of 5W. The module measures 175mm x 100mm x 50mm and weighs approximately 3.18kg.

Equipped with support for multiple communication protocols including Modbus, DNP3, and OPC, it offers Ethernet ports and RS-232/485 serial interfaces for seamless data exchange between Triconex systems and external devices. It incorporates redundant configuration and voting algorithms for enhanced reliability, plus safety features like fault detection and diagnostics. With a hot-swappable design, it can be replaced or upgraded without system shutdown, and it meets strict industry certifications including IEC 61508 SIL 2, ATEX, FM, and CSA for use in harsh and hazardous environments.
