Description
TRICONEX MP3101S2 Redundant Main Processor Module for Trident Safety Instrumented System (SIS)
Product Details
The MP3101S2 is the core main processor unit of TRICONEX Trident safety control platform, built on proven Triple Modular Redundancy (TMR) fault‑tolerant architecture. Powered by Motorola MPC860 32‑bit 50 MHz processor, it is equipped with 6 MB Flash PROM for system firmware and application storage, 16 MB DRAM for logic execution and Sequence‑of‑Events (SOE) data logging, plus 8 KB CRC‑protected NVRAM for retention of process variables. It runs on 24 VDC logic power and integrates multi‑channel communication interfaces including Modbus, TriBus, diagnostic bus and debug port. The module performs real‑time logic computation, cross‑channel voting, I/O data interaction and system diagnosis, supporting hot‑swap and on‑line maintenance without system shutdown. It complies with international safety standards and delivers stable performance under wide‑range temperature and heavy electromagnetic interference industrial conditions.
