CTI 2553-A 2-Channel Isolated Mag Meter Input Module

Description

The 2553-A 2-Channel Mag Meter Input Module rapidly measures the frequency

of a magnetic pulse tachometer with high resolution. It is designed to be compatible

with the CTI 2500 SeriesTM or Simatic® 505 I/O base in local, remote I/O,

and Profibus configurations.

Fast update time and high accuracy across the full frequency specification make the

2553-A ideal for gas turbine speed mea- surement applications.

Features

• Reflex counter

• N-tooth mode counting

• 1500 VDC isolation channel-to-channel

• 1500 VDC isolation channel-to-backplane

• Reports measurement in frequency or period
