PRECAUTIONS
WARNING
!
If not provided with proper prevention, it can cause death or fatal
injury or considerable loss of property.
CAUTION
!
If not properly observed, it can cause a hazard situation to result
in severe or slight injury or a loss of property.
CAUTION
!
CAUTION
!
Design Precautions
▶
Do not run I/O signal lines and
compensation wires near to high
voltage line or power line.
Separate them as 100 mm or
more as possible. Otherwise,
noise can cause module mal-
function.
CAUTION
!
Installation Precautions
▶Operate the PLC in the environ-
ment conditions given in the
general specifications.
▶If operated in other environment
not specified in the general spec-
ifications, it can cause an elec-
tric shock, a fire, malfunction or
damage or degradation of the
module
▶Make sure the module fixing pro-
jections is inserted into the mod-
ule fixing hole and fixed.
▶Improper installation of the mod-
ule can cause malfunction, dis-
order or falling.

CAUTION
!
Wiring Precautions
▶
When grounding a FG terminal, be sure to provide class 3 grounding which is dedicated to
the PLC. If not grounded, It can cause malfunction.
▶Before the PLC wiring, be sure to check the rated voltage and terminal arrangement for
the module and observe them correctly.
If a different power, not of the rated voltage, is applied or wrong wiring is provided, it can
cause a fire or disorder of the module.
▶Drive the terminal screws firmly to the defined torque.
If loosely driven, it can cause short circuit, a fire or malfunction.
▶Be careful that any foreign matter like wire scraps should not enter into the module.
It can cause a fire, disorder or malfunction.
WARNING
!
Test Run and Maintenance
Precautions
▶
Do not contact the terminals
while the power is applied.
It can cause malfunction.
▶When cleaning or driving a termi-
nal screw, perform them after the
power has been turned off
▶Do not perform works while the
power is applied, which can
cause disorder or malfunction.
CAUTION
!
▶
Do not separate the module from
the printed circuit board(PCB), or
do not remodel the module.
They can cause disorder, mal-
function, damage of the module
or a fire.
When mounting or dismounting
the module, perform them after
the power has been turned off.
▶Do not perform works while the
power is applied, which can
cause disorder or malfunction.

Chapter 1. INTRODUCTION
These two units are called G3F-RD3A and G4F-RD2A. The G3F-RD3Ais an Pt input module used with the
CPU of GLOFA GM1/2/3 series and MASTER-K1000S series, and the G4F-RD2A is used with the CPU of
GM4 series and K 300S series Hereafter, the two units are called the RTD input module
The RTD input module is a module that converts the temperature data(°C) input by the Pt (Pt100 or JPt100)
into a signed 16 bit digital binary data and outputs it.
1.1 Features
1) With direct connection of the RTD input module, the temperature data(°C) can be converted into a digital
value to be processed in the PLC.
2) The temperature data(°C) input can be processed to one digit after the point as a digital value.
3) One module can be connected to G3F-RD3A8-point or G4F-RD2A4-point Pt100 or JPt100.
4) The RTD input module has Pt100, Jpt100 or cable burn-out function at their every channel.
5) The RTD input module detects the out-of-range temperature that is input by Pt100 or JPt100.

Chapter 1. INTRODUCTION

1.2 Glossary
1.2.1 A -Analog Value
The continuous changeable value such as voltage, current, temperature, velocity, pressure and flow is
called analog value. For example, temperature changes continuously with time as shown in Fig. 1.1. The
PLC can process that continuous changeable temperature by use of the RTD input module.
1.2.2 D - Digital Value
In Fig.1.2, the number of man can be counted as 0, 1, 2, 3. The non-continuous changeable value as such
is called a digital value. On and Off signals can be denoted as a digital value 0 and 1, respectively.
Analog value cannot be directly input to the CPU
module for digital processing. Therefore, analog value
should be converted into a digital value to be input to
the CPU module. In addition, for external output of
analog value, digital value of the CPU module should
be converted into analog value.
1.2.3 Pt
This is a sensor that detects temperature as the type of resistance.
The Pt 100 outputs the resistance value of 100.00 Ωfor the temperature of 0 °C
1.2.4 Burn-out Function
If a part of the connected RTD or cable is disconnected, the out-of-range voltage is input by the internal
burn-out circuit and the connection or disconnection is detected.

2.4.4 Burn-out Detection Function
The RTD input module has the function of burn-out detection on the Pt100, JPt100 or cable.
1) As shown in the Fig. 2.2, if disconnection occurs in the RTD or cable then a voltage outside the
measurable range voltage is inputted by the internal burn-out detection circuit and burn-out detection
error code is generated.
2) The RTD input module can detect disconnection for each channel. But, burn-out detection is possible
only in the channels enabled.
3) If disconnection is detected in two or more wires, first, disconnection error code is generated by ‘b’and
then disconnection error code is generated by ‘A’or ‘b’ sequentially. If disconnection is detected
simultaneously in ‘A’and ‘B’, only disconnection error code is generated by ‘b’.

Chapter 3. INSTALLATIONAND WIRING
3.1 Installation
3.1.1 Installation Ambience
This module has high reliability regardless of its installation environment, but be sure to check the
following for system reliability and stability.
1)Ambience requirements
Avoid installing this unit in locations which are subjected or exposed to :
-Water leakage and dust.
-Continuous shocks or vibrations.
-Direct sunlight.
-Dew condensation due to rapid temperature change.
-Higher or lower temperatures outside the range of 0 to 55 °C
2) Precautions during installing and wiring.
-During drilling or wiring, do not allow any wire scraps to enter into the PLC.
-Install it on locations that are convenient for operation.
-Make sure that it is not located on the same panel that high voltage equipment located.
-Make sure that the distance from the walls of duct and external equipment be 50 mm or more.
-Be sure to be grounded to locations that have good ambient noise immunity.
3.1.2 Handling Precautions
From unpacking to installing the RTD input module, be sure to check the following:
1) Do not drop it off, and make sure that strong shock should not be applied.
2) Do not unload the PCB from its case. It can cause faults.
3) During wiring, be sure to check any foreign matter like wire scraps should not enter into the upper side
of the PLC. If any foreign matter has entered into it, alwayseliminate it.
4) Do not load or unload the module while the power supply is being connected.

Chapter 3. INSTALLATION AND WIRING
3 - 2
3.2 Wring Precautions
1) When connecting Pt with the RTD input module, refer to the Chapter 2.5 for wiring.
2) Be sure to separate the external input signal of the RTD input module from an alternating current so
that surge or induction noise generated from the alternating current could not effect.
3) When wiring, locating this unit too near from high temperature generating devicesor materials or
contacting it with the material like oil can cause short-circuit and occur damage or disorder.
4) When wiring to the terminal block, wiring with high-pressure wire or power supply wire can occur flow
inhibition and cause disorder or malfunction.
