TRICONEX 3511  Pulse input module

The TRICONEX 3511 pulse input module is a high-performance and highly reliable module widely used in industrial automation and process control systems, especially for measuring the frequency of rotating equipment. The following is a detailed introduction to the TRICONEX 3511 pulse input module:

Design feature: The TRICONEX 3511 pulse input module has been optimized and can be used with non amplifying magnetic speed sensors commonly found in rotating equipment such as turbines and compressors. This module detects voltage conversions from magnetic sensor input devices and accumulates these conversions (i.e. rate measurements) within a selected time window. Then, the generated count is used to generate frequency or RPM (revolutions per minute), which is then transmitted to the main processor.
Main parameters:
This module has eight non shared inputs and can be connected to multiple sensors simultaneously.
The resolution is 16 bits, with an accuracy of ± 0.01% in the range of 1000 Hz to 20000 Hz.
Having TMR (Triple Modular Redundancy) design means it has three identical circuit channels, providing high availability and reliability.

The input signal characteristics include AC coupling, balanced differential, impedance (load) typical value of 20KW, common mode range of -100 VDC to+100 VDC, normal mode range of 1.5V to 200 V peak to peak, and have over range protection and hysteresis function.
Suitable for various waveforms such as sine, square, and pulse, with a duty cycle ranging from 10% to 90%.
Application environment: The module is installed in a sturdy metal casing that meets the NEMA 4X rating and has a conformal coating to protect it from natural factors. Therefore, it can operate stably in various harsh industrial environments.
Industry applications: The TRICONEX 3511 pulse input module has been widely used in industries such as oil and gas, power generation, and manufacturing.
Diagnosis and protection: Each input channel independently processes all data input to the module and passes the data to the main processor. The main processor votes on the data to ensure its integrity and accuracy. In addition, each module provides complete continuous diagnosis on each channel. Any diagnostic failure on any channel will activate the fault indicator, which may in turn activate the chassis alarm signal.
Overall, the TRICONEX 3511 pulse input module is a powerful and high-performance industrial automation module suitable for various applications that require high-precision and high reliability frequency measurement.
