Invensys TRICONEX HCU3700/3703E Isolated Analog Input Module
The AI3351 Analog Input (AI) Module has three independent input channels. Each input channel receives variable voltage signals from each point, converts them to digital values, and transmits the values to the three MPs on demand. One value is then selected using a mid-value selection algorithm to ensure correct data for every scan. Sensing of each input point is performed in a manner that prevents a single failure on one channel from affecting another channel.
The AI3351 AI Module sustains complete, ongoing diagnostics for each channel. If the diagnostics detect a failure on any channel, the module's Fault indicator is activated, which in turn activates the system alarm. The Fault indicator points to a channel fault, not a complete module failure. The AI Module is guaranteed to operate properly in the presence of a single fault and may continue to operate properly with multiple faults.
The AI3351 AI Module supports hot sparing for online replacement of a faulty module or continuous back-up to an active module. The AI Module is mechanically keyed to prevent improper installation in a configured baseplate.
