CHAPTER 1 OVERVIEW

This user's manual explains the specifications, operations, and programming method of
the AJ65SBT2B-64AD analog-digital converter module (hereafter abbreviated as
AJ65SBT2B-64AD) used as a remote device station of a CC-Link system.
The AJ65SBT2B-64AD changes analog values (voltage or current) to digital values (16-bit
signed binary).

- 1 1.1 Features
One module enables an A/D conversion with 4 channels.
I/O conversion characteristics can be changed by setting an analog input range in
each channel.
High-speed conversion of 200µs/channel is achieved.
In all analog input ranges, high resolution of 1/16000 is achieved.
The module performs an A/D conversion in accuracy of ±0.2%
digital output value when the operating ambient temperature is within 0 to 55°C.
* 1 Except when receiving noise influence.
A conversion processing method for each channel can be selected from the sampling
processing, time average processing, count average processing or moving average
processing.
(a) Since the module has a built-in terminating resistor (110Ω), a terminating resistor
is not necessary when the module is used on the network terminal. In addition,
one operation with a switch can make the built-in terminating resistor invalid.
(b) The transmission speed need not be set by the user since it is automatically
determined according to the transmission speed set in a master station.
(c) The offset/gain setting can be configured by simple operations without the
connection to the master module.
