Doing so may occasionally result in minor injury due to electric
shock.
Do not touch the terminals or the electronic components or pat-
terns on the PCB within 1 minute after turning OFF the power sup-
ply. Doing so may occasionally result in minor injury due to electric
shock.
Do not allow pieces of metal, wire clippings, or fine metallic shav-
ings or filings from installation to enter the product. Doing so may
occasionally result in electric shock, fire, or malfunction.
Do not use the product in locations where flammable or explosive
gases are present. Doing so may occasionally result in minor or
moderate explosion, causing minor or moderate injury, or property
damage.
Do Not disassemble, modify, or repair the product or touch any of
the internal parts. Minor electric shock, fire, or malfunction may
occasionally occur.
Tighten the screws on the terminal block to the following specified
torque. Loose screws may occasionally cause fire, resulting in
minor or moderate injury, or damage to the equipment.
Terminal block screws: 0.40 to 0.56 N·m
Perform correct setting of the product according to the application.
Failure to do so may occasionally cause unexpected operation,
resulting in minor or moderate injury, or damage to the equipment.
A malfunction in the Product may occasionally make control oper-
ations impossible or prevent alarm outputs, occasionally resulting
in property damage to the system or equipment connected to the
Product. To maintain safety in the event of malfunction of the
Product, take appropriate safety measures, such as installing a
monitoring device in a separate system.
Do not use the equipment for measurements within measurement
categories II, III, or IV (according to IEC61010-1). Doing so may
occasionally cause unexpected operation, resulting in minor or
moderate injury, or damage to the equipment. Use the equipment
for measurements only within the measurement categories for
which the product is designed.
The service life of the output relays depends on the switching
capacity and switching conditions. Consider the actual application
conditions and use the product within the rated load and electrical
service life. Using the product beyond its service life may occa-
sionally result in contact welding or burning.

VI
(1) Use and store the Digital Controller in the range of specifications for ambient
temperature and humidity. The service life will decrease due to increased
internal temperature if multiple Digital Controllers are mounted closely side by
side or one on top of the other. If this type of mounting is used, use forced
cooling, e.g., use a fan to blow air onto the Digital Controllers.
(2) Do not prevent heat dissipation by obstructing the periphery of the Digital
Controller. Do not block the vents on the Digital Controller unit.
(3) The supplied power voltage and load must be within the rated and specified
ranges.
(4) Be sure to confirm the name and polarity for each terminal before wiring the
terminal block.
(5) Do not connect anything to unused terminals.
(6) Use the specified size of crimp terminals (M3, width: 5.8 mm max.) to wire the
terminal block. When connecting bare wires, use copper stranded or solid
wires, and use AWG22 (cross-sectional area of 0.326 mm2) to AWG14 (cross-
sectional area of 2.081 mm2) for the power supply terminals and AWG28
(cross-sectional area of 0.081 mm2) to AWG16 (cross-sectional area of 1.309
mm2) for other terminals. (Length of exposed wire: 6 to 8 mm)
(7) Ensure that the rated voltage is attained within 2 seconds after turning ON the
power.
(8) Turn OFF the power first when you need to draw out the Digital Controller. Do
Not touch the terminals or the electronic components, or subject them to
physical shock. When inserting the Digital Controller, do not allow the
electronic components to contact the case.
(9) Do not remove the inner circuit board.
(10) The output may turn OFF when shifting to certain levels. Take this into consid-
eration when performing control.
(11) Allow a warm-up time of at least 30 minutes.
(12) To prevent inductive noise, separate the Digital Controller terminal block wiring
from power lines that carry high voltages or high currents. Also, do not wire
power lines together with or parallel to the Digital Controller wiring. Using
shielded cables and separate conduits or ducts is recommended.
Attach a surge suppressor or noise filter to peripheral devices that generate
noise (in particular, motors, transformers, solenoids, magnetic coils, or other
equipment that has an inductive component). When a noise filter is used at the
power supply, first check the voltage or current, and attach the noise filter as
close as possible to the product. Allow as much space as possible between the
product and devices that generate powerful high frequencies (e.g., high-
frequency welders, high-frequency sewing machines) or surge.
(13) Install a switch or circuit breaker that allows the operator to immediately turn
OFF the power, and label suitably.
(14) The product is designed for indoor use only.
Do not use the product outdoors or in any of the following locations.
· Locations where dust or corrosive gas is present (in particular, sulfur or
ammonia gases)
· Locations where condensation or ice may form
· Locations directly exposed to sunlight
· Locations subject to strong shocks or vibration
· Locations where water or oil may splatter on the Digital Controller
· Locations directly exposed to radiant heat from heating equipment
· Locations subject to sudden or extreme changes of temperature
(15) Do not use paint thinner or similar chemical to clean with. Use standard grade
alcohol.
Precautions for Safe Use

VII
●Service Life
Use the product within the following temperature and humidity ranges:
Temperature: −10 to 55°C (no icing or condensation)
Humidity: 25% to 85%
When the product is installed inside a control panel, make sure that the temperature
around the product, not the temperature around the control panel, does not exceed
55°C.
The service life of this product and similar electronic devices is determined not only
by the number of switching operations of relays but also by the service life of
internal electronic components. Component service life is affected by the ambient
temperature: the higher the temperature becomes, the shorter the service life
becomes and, the lower the temperature becomes, the longer the service life
becomes. Therefore, the service life can be extended by lowering the temperature
of the product.
Be sure to install the product according to the specified conditions. Otherwise, the
heat generated by the product will cause the internal temperature to rise, short-
ening the service life. If necessary, cool the product using fans or other means of air
ventilation.
When providing forced cooling, however, be careful not to cool down the terminals
sections alone to avoid measurement errors.
●Noise Countermeasures
To prevent inductive noise, separate the wiring for the product's terminal block and
connector from high-voltage, high-current power lines. Do not run the wiring parallel
to or in the same cable as power lines. The influence of noise can also be reduced
by using separate wiring ducts or shield lines.
Install surge absorbers or noise filters in devices near the product that generate
noise (in particular, devices with an inductance component, such as motors, trans-
formers, solenoids, and magnetic coils).
If a noise filter is used for the power supply, check the voltage and current, and
install the noise filter as close as possible to the product.
Separate the product as far as possible from devices generating strong high-
frequency noise (e.g., high-frequency welders and high-frequency sewing
machines) or surges.
●Measurement Accuracy
When extending the thermocouple lead wire, be sure to use a compensating wire
that matches the thermocouple type.
When extending the lead wire of the platinum resistance thermometer, be sure to
use wires that have low resistance, and make sure that the resistances of the three
lead wires are the same.
If the measurement accuracy is low, check whether the input shift is set correctly.
●Waterproofing
The degree of protection is as shown below.

Overview
1.1 Main Features of the E5AR-T and E5ER-T
The E5AR-T/ER-T is an advanced Programmable Digital Controller that features high-precision control.
The E5AR-T/ER-T has the following features.
■Inputs
●High-speed
Sampling
• Sampling period: 50 ms
●High Accuracy and
High Resolution
• Indication accuracy
Thermocouple: (Larger of ±0.1% PV or ±1°C) ± 1 digit max.
Platinum resistance thermometer:
(Larger of ±0.1% PV or ±0.5°C) ± 1 digit max.
Analog input: (±0.1% FS) ± 1 digit max
(For non-standard specifications, refer to Appendix Specifications
(P. A-2))
• Input resolution: 1/100°C
(Pt100: A range of −150.00 to 150.00°C with a resolution of 0.01°C
is provided.)
• High-speed sampling is achieved simultaneously with high accuracy
and high resolution. This provides high-accuracy, high-speed control
to match your application.
●Multi-input
Function
• A wide range of temperature inputs and analog inputs is supported.
Temperature inputs:
Thermocouples: K, J, T, E, L, U, N, R, S, B, W
Platinum resistance thermometers: Pt100
Analog inputs:
Current inputs: 4 to 20 mA or 0 to 20 mA
Voltage inputs: 1 to 5 V, 0 to 5 V, or 0 to 10 V
●Multiple Inputs • The E5AR-T is available with either 2 input or 4 input channels.
The E5ER-T comes with 2 inputs.
■Controller
●Programs • Up to 32 programs can be created containing set points, times, PID
set numbers, alarm set numbers, wait upper/lower limits, segment
outputs, program repetitions, and program links. The set point,
times, wait function, and segment outputs can be set for each
segment. Outputs can be set for each segment or outputs can be
set based on the time from the start of the segment.
●PID Sets • Up to 8 PID sets can be created to store settings (PID constants,
MV limits, and automatic selection range upper limits) for PID
control.

1.1 Main Features of the E5AR-T and E5ER-T
1-3
Overview
• PID sets can be selected not only by directly specifying the PID set
number in a program, but they can also be selected automatically
according to the present value, deviation, or set point.
●A wide Variety of
Control Modes and
Functions
• Coordinated operation is possible with one Digital Controller for
models with 2 or 4 input channels, eliminating the need for slave
adjusters.
• Position-proportional Control Models support floating control or
closed control. Floating control allows position-proportional control
without a potentiometer.
■Outputs
●Multi-output
Function
• Multi-outputs enable using either current outputs or voltage outputs
(pulses).
●High Resolution • Resolution of Current Outputs
0 to 20 mA: Approx. 54,000
4 to 20 mA: Approx. 43,000
●Control Period • The control period can be set as short as 0.2 seconds, allowing
precise time-proportioning control for voltage output pulses.
