Triconex V2-V35101S2 Pulse Input Module

Description

• Environmental Specifications
  • Operating Temperature: -40°C to +70°C, which can adapt to the harsh temperature environment of industrial sites such as cold areas and high – temperature workshops.
  • Relative Humidity: 5% – 95% (no condensation), which can work stably in humid on – site environments without circuit short – circuit faults caused by moisture.
  • Anti – Interference Performance: It has strong anti – electromagnetic interference capability, can resist the electromagnetic interference generated by on – site electrical equipment, and ensure the accuracy of pulse signal collection.

Functional Characteristics

• TMR Architecture for High Reliability
  • Three independent pulse counting channels run in parallel, and a 2 – out – of – 3 voting mechanism is adopted. When one channel fails, the system can still output accurate counting results through the other two normal channels, which eliminates the single – point failure risk.
  • Each channel has independent electrical isolation and fault detection functions, which can quickly locate and isolate the faulty channel, and send fault alarm information to the main control system in time without affecting the operation of other channels.
• High – Speed and Accurate Pulse Processing
  • It can process pulse signals with a frequency of up to 20kHz in real time, and accurately capture pulse signals with a width of only 25 microseconds, which can meet the counting needs of high – speed rotating equipment such as turbines and high – flow fluid meters.
  • The 32 – bit counter of each channel can realize long – term and large – capacity data counting, and the data is transmitted to the main processor through the TMR bus, with fast transmission speed and high data accuracy, and no data loss or distortion will occur.
• Comprehensive Diagnostics and Easy Maintenance
  • It has built – in comprehensive self – diagnostic functions, which can monitor the working status of the module in real time, including power supply status, channel connection status and counting function status, and feed back diagnostic information to the upper monitoring system.
  • It supports hot – swap operation. When the module needs to be maintained or replaced due to a fault, it can be replaced online without shutting down the entire safety system, which greatly reduces the maintenance time and production loss caused by shutdown.
  • It has good compatibility and can be seamlessly connected with Triconex main processor modules such as MP3101S2, and the configuration and parameter setting are simple, which can be completed through TriStation software.
