NOTES
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, 12 13 7 8 are for CP1 (A phase), CP2 (B phase) RST1 and RST2 inputs (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. The type of OUT2 is determined by the model 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).
