General Information about TSX CTY2A/4A and TSX CTY2C Couplers

At a Glance

The TSX CTY2A, 4A and 2C modules are the counting modules used with the Premium modular PLC range. To execute this function, they support all the functions of the Control Expert software.

These modules feature:

functions designed to release tasks from the processor that are directly related to counting (comparisons, captures, preset or reset to zero, fault detection, etc.)
event generation functions for the application program,
TOR outputs configurable as reflex outputs, adapted to fast actions.

These modules constitute a variable characteristic range, adapted to different industrial control situations.

Main characteristics

The main characteristics of these modules are the following:

Type	Functions	Number of channels per module	Number of physical outputs per channel	Maximum frequency (kHz)
TSX CTY2A	Counting, down counting, up / down counting.	2	1 or 2 (depending on the function)	40
TSX CTY4A	Counting, down counting, up / down counting.	4	1 or 2 (depending on the function)	40
TSX CTY2C	Counting / down counting, speed measurement / monitoring.	2	4	1000

The TSX CTY2A and 4A modules are functionally identical. Their only difference is the number of channels.
