Tricon 3515 Pulse Totalizer Input Module

The Type 3515 Pulse accumulator Input (PTI) module provides 31 bit counters operated independently by 32 individuals. A counter with an active flow sensor or a unit sensor measures (counts) a certain amount transmitted to the main processor. in
Control specifies the time when the master processor clears a single counter or all counters. The PTI module has three isolated input channels. Each input channel independently processes all input data and passes it to the main processor, where it votes before processing to ensure the highest integrity. Each PTI module provides integrity

Diagnose each channel; Includes channel to channel count comparison. Any diagnostic failure activates the Fault indicator on any channel, which in turn activates the chassis alarm. The fault indicator indicates channel failure, not module failure. PTI modules are guaranteed in… In the presence of normal operation
Single error, and may continue to operate specific kinds of multiples of the shortcoming. The PTI module can be used or operated
There is no hot spare module. If you use a hot spare module, it re-educates all counter values from the active module.
