Introduction to the Invensys TRICONEX Conjisen 9761-210 module product. The Invensys TRICONEX Conjisen is the most advanced controller that provides fault tolerance through a Triple Modular Redundancy (TMR) architecture. TMR integrates three isolated parallel control systems and extensive diagnostic functions in a control system. The TRICONEX 9761-210 system uses two-thirds of the votes to provide high integrity, error free, uninterrupted process operations, and no single point of failure. The TRICONEX 9761-210 controller uses three identical channels. Each channel independently executes control programs parallel to the other two channels. A dedicated hardware/software voting mechanism identifies and verifies all digital inputs and outputs on site, while analog inputs require a medium value selection process. TRICONEX 9761-210 Since each channel is isolated from other channels, a single point of failure in any channel will not be transmitted to another channel. If a hardware failure does occur on one channel, other channels will overwrite it. Meanwhile, when the controller is online, the faulty module can be easily disassembled and replaced without interrupting the process.
