Invensys Triconex 3511 Pulse Input Module

The Triconex 3511 is a pulse input module that is used to interface with devices that generate pulse signals, such as flow meters, encoders, and tachometers. It has eight non-commoned inputs and a resolution of 16 bits. The accuracy of the module is ±0.01% from 1000 Hz to 20,000 Hz.

The 3511 module is a Type TMR module, which means that it uses a time-to-measure method to determine the frequency of the input signal. This method is very accurate and is not affected by noise on the input signal.

The 3511 module is used in a variety of applications, including:

• Flow measurement

• Speed measurement

• Position measurement

• Event counting

• Process control

Here are some of the key technical specifications of the Triconex 3511 pulse input module:
