This user's manual explains the specifications, handling, programming methods and others of Type AJ65SBT-64AD analog-digital converter module (hereafter abbreviated to the "AJ65SBT-64AD") which is used as a remote device station of a Control & Communication Link (hereafter abbreviated to "CC-Link") system.

The AJ65SBT-64AD converts the analog signals (voltage or current input) from the PLC's external source to a 16-bit encoded binary data digital value.

1.1 Features

This section gives the features of the AJ65SBT-64AD.

(1) High accuracy

This module performs A/D conversion at the accuracy of ±0.4% relative to the maximum value of the digital output value at the operating ambient temperature of 0 to 55°C, or at ±0.2% relative to the maximum value of the digital output value at the operating ambient temperature of 25±5°C.

(2) Input range selectable per channel

You can choose the analog input range per channel to change the I/O conversion characteristics.

(3) High resolution of 1/±4000

By changing the input range, you can choose and set the digital value resolution to either 1/4000 or 1/±4000 (when the -10 to +10V range or user range setting 1 is selected) to provide high-resolution digital values.

(4) Designation of sampling processing or moving average processing

As a conversion method, you can specify sampling processing or moving average processing per channel.

(5) Smaller than the conventional A/D converter module

This module is 60% smaller in installation area and 38% less in volume than the conventional CC-Link A/D converter module (AJ65BT-64AD).

(6) Up to 42 modules connectable

You can connect up to 42 AJ65SBT-64AD modules to one master station.
