SAFETY PRECAUTIONS
(Read these precautions before using.)
When using Mitsubishi equipment, thoroughly read this manual and the associated
manuals introduced in this manual. Also pay careful attention to safety and handle
the module properly.
These precautions apply only to Mitsubishi equipment. Refer to the CPU module
user's manual for a description of the PC system safety precautions.
TheseySAFETYPRECAUTIONSyclassify the safety precautions into two categories:
"DANGER" and "CAUTION".
!DANGER
Procedures which may lead to a dangerous condition and
cause death or serious injury if not carried out properly.
#
CAUTION
Procedures which may lead to a dangerous condition and
cause superficial to medium injury, or physical damage
only, if not carried out properly.
Depending on circumstances, procedures indicated by #CAUTION may also be linked
to serious results.
In any case, it is important to follow the directions for usage.
Store this manual in a safe place so that you can take it out and read it whenever
necessary. Always forward it to the end user.

[DESIGN PRECAUTIONS]
!DANGER
l
Configureasafetycircuit external to the PC, so that the entire system operates
safely even if there is an external power error or if the PC is malfunctioning.
(1) The external output are as shown below, depending on the output status
setting in the external-output control setting mode:
Please be careful when performing the setting.
Refer to the Detailed Manual’s Item 3.3.12 about the output status.
(2) Due to malfunction of the output element or its internal circuit, normal output
may not be obtained, or erroneous output may be performed.
For output signals that may cause a severe accident, set an external circuit
to monitor the output.
[DESIGN PRECAUTIONS]
#
CAUTION
l
Do not bundle, or near the control cables and communication cables with the
main circuit and power cables. Keep them at least 100mm (3.94inch) away from
such cables. Noise may cause erroneous operation.

[INSTALLATION PRECAUTIONS]
#
CAUTION
l
Use the PC in the environment given in the general specifications of this manual.
Using the PC outside the range of the general specifications may result in
electric shock, fire or malfunction, or may damage or degrade the module.
l
Insert the tabs at the bottom of the module into the mounting holes in the base
module before installing the module. Tighten the module fixing screws by the
specified torque. Improper installation may result in malfunction, breakdowns
or cause the module to fall out.
l
Do not directly touch the module’s conductive parts or electronic components.
Doing so could cause malfunction or trouble in the module.
[WIRING PRECAUTIONS]
#
CAUTION
l
Be sure to ground the shield wire with a special PC ground of Type III or above.
Not doing so could result in erroneous operation.
l
When wiring in the PC, be sure that it is done correctly by checking the product’s
rated voltage and the terminal layout. Connecting a power supply that is
different from the rating or incorrectly wiring the product could result in short
circuit or damage.
l
Tighten the terminal screws to the specified torque.
Loose terminal screws may cause a short circuit, fire, or erroneous operation.
l
Be sure that cuttings, wire chips, or other foreign matter do not enter the
module.
Foreign matter may start a fire or cause an accident or erroneous operation.

[STARTING AND MAINTENANCE PRECAUTIONS]
!DANGER
l
Do not touch the terminal before all phases of the power supply have been
obstructed from the outside.
It may cause erroneous operation.
l
Make sure all phases of the power supply have been obstructed from the outside
before cleaning the module or retightening the screws. Failure to completely
shut off the all phases of the power supply phases may cause damage to the
module or cause erroneous operation.
#
CAUTION
l
Never disassemble or modify the module. This may cause breakdowns,
malfunction, injury and/or fire.
l
Switch all phases of the external power supply off before mounting or removing
the module. If you do not switch off the external power supply, it will cause
failure or malfunction of the module.
[DISPOSAL PRECAUTIONS]
#
CAUTION
l
When disposing of this product, handle it as industrial waste.

1.General Description
This user’s manual describes the specification, name of each part, wiring, etc.
of the following modules, which can be used with the MELSEC-A series
AnS/QnAS CPU module (abbreviated as PC CPU from here on).
lA1S64TT-S1 Temperature Control Module
(abbreviated as A1S64TCRT-S1 from here on)
lA1S64TCRTBW-S1 Temperature Control Module
(abbreviated as A1S64TCRTBW-S1 from here on)
1. A1S64TCRT-S1
The A1S64TCRT-S1 is a special module that performs temperature
adjustment, which converts the external platinum temperature-measuring
resistor input value to a digital value in 16-bit encoded BIN format and
performs PID operation automatically.
2. A1S64TCRTBW-S1
The A1S64TCRTBW-S1 is a module which enhances the A1S64TCRT-S1
with a function to detect the disconnection of the input power to the
controlling device.
3. Temperature input and control output type
The temperature input type and control output type of each temperature
control module are indicated below:
