1. OVERVIEW
This user's manual explains the specifications, part identification and wiring for the products listed
below, which are used as remote device stations for the CC-Link system:
The AJ65BT-64RD3 is a 3-wire system connecting module for the platinum temperature-measuring
resistor.
The AJ65BT-64RD4 is a 4-wire system connecting module for the platinum temperature-measuring
resistor.
(Hereinafter, the AJ65BT-64RD3 and AJ65BT-64RD4 will be collectively referred to as AJ65BT-64RD.)
The AJ65BT-64RD converts temperature data input from platinum temperature-measuring resistor Pt
100 (abbreviated as Pt 100 from here on) or platinum temperature-measuring resistor JPt 100
(abbreviated as JPt 100 from here on) to 16-bit signed BIN data (up to the first decimal place), or 32-
bit signed BIN data (up to the third decimal place).
1.1 Features
The following describes the features of AJ65BT-64RD.
(1) Stores temperature data
By directly connecting the old JIS or new JIS IEC type platinum temperature-measuring resistor
to AJ65BT-64RD, temperature data [°C] may be received as digital values.
For the detected temperature, values to the first place and third place below decimal point are
stored in the remote register.
(2) Conversion is possible at four channels per module.
Conversion of temperatures into digital values can be carried out at four channels in a single
AJ65BT-64RD module.
Also, the conversion enable/disable can be specified for individual channels.
(3) Designation of sampling processing and travel average processing
As a conversion method, either sampling processing or travel averaging processing can be
selected for each channel.
(4) Wire breakage detection is possible at individual channels.
The wire breakage of platinum temperature-measuring resistor or cable can be detected for each
channel.
(5) High overall accuracy
High-accuracy temperature detection is feasible with a tolerance of ±0.25 % of the full scale in
overall accuracy for normal temperature detection, and ±0.1 % of the full scale when the ambient
temperature is in the normal temperature range (25 °C ±5 °C).

POINT
The above are examples of processing time until the control of the output signal to the AJ65BT-
64RD from the programmable controller CPU or until input signals or remote registers are read.
The maximum time that takes for updating the detected temperature read by the programmable
controller CPU is “data link processing time + sampling time.”
