Triconex 3515 Pulse totalizer, 24 VDC, 32 pts.

Key Features and Benefits

 

  • Triple Modular Redundancy (TMR): The 3515 module uses the TMR architecture, which is a hallmark of Triconex systems. It features three independent input channels that process the pulse count data in parallel. The main processors then use a two-out-of-three (2oo3) voting mechanism to ensure the data is accurate and free from errors caused by a single point of failure. This design guarantees uninterrupted operation and the highest level of system integrity.
  • High-Accuracy Counting: The module provides precise counting with an impressive resolution of up to 0.1 microseconds, ensuring highly accurate measurement. It can handle pulse frequencies from 1 Hz to 20 kHz, making it versatile for a wide range of industrial applications.
  • 32 Independent Channels: The module offers 32 independent, 31-bit counters. This high density of input points allows you to connect multiple pulse-generating devices to a single module, simplifying wiring and reducing the need for additional hardware.
  • Opto-Isolated Inputs: The inputs are optically isolated to minimize electrical interference and noise, ensuring that the pulse counts are accurate and reliable. This isolation also enhances the integrity and safety of the system.
  • Comprehensive Diagnostics: The 3515 includes built-in diagnostics for each channel. This allows for easy troubleshooting and maintenance by quickly identifying any faults or anomalies in the pulse input signals or the module itself.
  • Hot-Swap Capability: Like other Triconex I/O modules, the 3515 can be replaced online without disrupting the process. This hot-swap capability is crucial for maintaining plant availability and minimizing downtime during maintenance.
