CTA USER MANUAL

FORWORD

This user manual provides handy instructions for the operation of Delta CTA series. The detailed

operational instructions help the user to easily locate the functions they would like to acquire. In addition,

this user manual also helps sales and engineering staff to understand more about the advantages of Delta

CTA series and assist the users to operate CTA as well as getting familiar with its functions. The date of the

latest update is shown in the bottom left of the page.

How to use CTA correctly…

 To avoid misaction caused by interference, please make sure if you isolate the I/O wiring when I/O

wiring and power cable or high-voltage cable in the same wiring tube. If possible, use a separate tube

for the I/O wiring.

 Make sure that you place the sensor, other input devices, signal cables and CTA away from the

interference source.

 It will require 200ms after CTA is switched on for the activation of the internal power and default

value reset. CTA may not operate normally during this period of time.

CHAPTER ONE: BASIC INSTRUCTIONS

1.1 Features

Delta CTA series is the 3-in-1 timer, counter and tachometer with the following features:

 Can be a timer, counter, or tachometer and can operate in timer + counter mixed mode.

 Offers voltage input (PNP) or non-voltage input (NPN).

 The Pre-Scale function allows the input pulses to be displayed in their actual units.

 Counting speeds available: 1/30/200/1K/5K/10K cps. Maximum: 10K cps.

 The counting can be conducted in millisecond, second, minute, minute/second and

hour/minute/second.

 Output 1 contains relay output and transistor output. The two types of outputs can be enabled

concurrently.

 Offers total counting and batch counting.

 “Reset” and “Lock” keys for more convenient use.

 Offers 6-digit double-line LCD display.

 Offers easy DIP switch setup.

 Decimal point setup available.

1.2 Ordering Information

There are currently two model types available: CTA4000A and CTA4100A, only differentiating in the type of output 2.

1.6 Terminal Definition

CTA combines the functions of timer, counter and tachometer; therefore, the definitions of input terminals in different modes are slightly different. CTA has 4 terminals ready for inputs. Take the pins

in counter mode for example, (see figure 1).

The output terminals are for OUT1 and OUT2. OUT1 has two outputs, transistor output and relay output, and the two outputs operate concurrently name. For CTA4000A, OUT2 only offers transistor output with inductive load protection diode (see figure 2). For CTA4100A, OUT2 only offers relay output (see figure 3).
