Triconex 3351S2 Controller Features

Pulse Input Module

On a PI Module, each channel measures the input frequency independently. Special algorithms, optimized for accurately measuring the speed of rotating machinery, are used to compensate for irregularly spaced teeth on timing gear or for periodic acceleration/de-acceleration. The results are placed into a table of values. Each input table is passed to its associated MP using the corresponding I⁄O bus. The input table in each MP is transferred to its neighbors across the TriBus. The middle value is selected by each MP and the input table in each MP is corrected accordingly. In TMR mode, the mid-value is used by the application; in duplex mode, the average is used. Special self-test circuitry is provided to diagnose the health state of all input points, even when an active signal is not present. Each PI Module is guaranteed to remain in calibration for the life of the controller; periodic manual calibration is not required.

Solid-State Relay Output Module

On a Solid-State Relay Output (SRO) Module, output signals are received from the MPs on each of three channels. The three sets of signals are voted and the voted data is used to drive the 32 individual relays. Each output has a loop-back circuit which verifies the operation of each relay switch independently of the presence of a load. Ongoing diagnostics test the operational status of the SRO Module.

The SRO Module is a non-triplicated module for use on non-critical points which are not compatible with high-side, solid-state output switches; for example, interfacing with annunciator panels.
