(1) The status of analog output changes depending on the setting of various functions that

control the analog output. Take sufficient caution when setting for those functions.
For details of analog output status, refer to Section 3.4.1 "

Combinations of functions in each

part

"

(2) Normal output may not be obtained due to malfunctions of output elements or the internal

circuits.
Configure a circuit to monitor signals which may lead to a serious accident.

!

CAUTION

Do not bunch the control wires or communication cables with the main circuit or power wires, or

install them close to each other.

connects an offset value and a gain value at the time when a digital value set from the
PLC CPU is converted into an analog value (voltage or current output).
The offset value is an analog value (voltage or current) output when the digital value
set from the PLC CPU is 0.
The gain value is an analog value (voltage or current) output when the digital value set
from the PLC CPU is 4000.

3.3.3 Relationship between offset/gain setti ng and anal og output v al ue

How to calculate the analog output value:
The resolution of AJ65SBT-62DA can be set arbitrarily by modifying the setting of the
offset value and gain value.
How to calculate the analog value resolution and the analog output value for a given
digital input value when the settings of the offset value and gain value are changed is
shown next.

(1) Resolution

Find the resolu ti on wi th the fo llow i ng exp r e ssi on .

(Gain value) - (Offset value)

(Analog resolution) =

4000

(2) Analog output value

Find the analog out put valu e wi th th e following expressio n.

(Analog output) = (Analog resolution) × (Digital input value) + (Offset value)

3.3.4 Accuracy

Accuracy is relative to the maximum value of the analog output value.
If you change the offset/gain setting or output range to change the output
characteristic, accuracy does not change and is held within the range indicated in the
performance specifications.

(1) Accuracy of voltage output

For voltage output, the maximum value of the analog output value changes with
the range.
For example, accuracy is relative to 5V when the 0 to 5V range is selected.
Analog output is provided at the accuracy of within ±0.2% (±10mV) when the
operating ambient temperature is 25±5°C, or within ±0.4% (±20mA) when the
operating ambient temperature is 0 to 55°C.

3.3.5 Conversion speed

Conversion speed indicates time required to read the digital output value written to the
buffer memory, perform D/A conversion, and then output the specified analog value.
Conversion speed pe r cha n nel of t he AJ 65S B T-62DA i s 1 ms.
Due to the data link processing time of the CC-Link system, there is a transmission
delay until the D/A conversion value is read actually.
For the data link processing time, refer to the user's manual of the master module
used.

Example) Data link processing time taken in the asynchronous mode when the master

module is the QJ61BT11 (normal value)

4.8 Wiring

This section provides the instructions for wiring the AJ65SBT-62DA and its wiring with
external equipment.

4.8.1 Wiring precautions

To obtain maximum performance from the functions of AJ65SBT-62DA and improve
the system reliability, an external wiring with high durability against noise is required.
The precautions when performing external wiring are as follows:
(1) Use separate cables for the AC and AJ65SBT-62DA external input signals, in

order not to be affected by the AC side surge or conductivity.

(2) Do not bundle or place with load carrying wires other than the main circuit line,

high voltage line or PLC. Noises, surges, or conductivity may affect the system.

(3) Place a one-point grounding on the PLC side for the shielded line or shielded

cable.

(2) Precautions for replacing the conventional product (AJ65BT-

64DAV/DAI) with the AJ65SBT-62DA

In the existing system using the conventional product (AJ65BT-64DAV/DAI), the
following instructions must be noted when changing the AJ65BT-64DAV/DAI for
the AJ65SBT-62DA.

(a) Since the AJ65SBT-62DA occupies one station (the AJ65BT-64DAV/DAI

occupies two stations), the station information setting in the network
parameters must be changed.

(b) As the remote I/O signals and remote register settings are different between

the two models, the program of the conventional model cannot be utilized.

(c) Because of the differences in shape and layout between the terminal blocks,

you cannot use the terminal block of the conventional module as it is.

(d) The offset/gain setting method differs. For details, refer to Section 4.4.

(e) The ways to set the station number and transmission speed setting switches

are different. For details, refer to Section 4.3.
