4-3-2. Basics of wiring
Precaution
In order to avoid accidents always read and understand these contents.
1. Connecting to the terminal
①For wiring of terminal use crimp style terminal with insulating sleeve. Always use Ｏtype terminal to
secure safety of power supply terminal and grounding terminal. For other types of terminals also we
recommend that you use Ｏtype terminal.
②When the terminal screws are tightened the torque is '0.6 - 0.8 Nm'. If a torque exceeding this value is
applied, terminal screw panel gets damaged hence take care.
2. Power supply terminal
①In power supply, place the over current protection device and switch that conforms to the ratings of the
controller, within 3m so that they are easily reachable.
②Use a power supply with 600V vinyl insulation electric line (rating more than 1A AC) and an equal or
greater electric line.
③To avoid malfunctioning use good quality single phase power supply with little voltage change, wave form
distortion and noise. If the noise is loud use noise filter and insert insulation transformer etc.
④There is a little leakage of current flow in case of rated power supply hence take care. Leaking current is
approximately 1mA.
Warning
To avoid serious accidents always cut off the power supply and then do the
wiring.

3. Input terminal
①Maximum permitted input of input terminal is as follows. Take care of not applying the input that exceeds
these values. If an input that exceeds the range is applied, the product may get out of order or its
performance may deteriorate remarkably or it may malfunction.
・Thermocouple, voltage mV, voltage V : Less than ±20V.
・Resistance thermometer
: Less than 500Ωor Less than ±5V.
・Current mA
: Less than ±30mA or Less than ±7.5V.
②Parallel connection of input is not allowed. Not only measurement error occurs, but also stable control is
not performed and an error occurs in the entire system.
③For thermocouple, do the wiring up to the input terminal of the product by a thermocouple or compensation
lead wire.
④To avoid measurement error for resistance thermometer, use cable such that resistance value of each wire
is equal. Take care as burn out is not provided 4-wire resistance thermometer.
⑤When connecting a protection device like zenner barrier for input protection, sometimes a big
measurement error may occur. Confirm the combination with protection device and maintain the allowable
signal source resistance and allowable wire resistance of the controller.
4. Output terminal
①Use an output terminal within the rating range. If a load that is out of range is connected, product may get
out of order, its performance may show a remarkable deterioration or it may malfunction.
②For relay output terminal of ON OFF pulse type and ON OFF servo type connect the load through buffer
relay. For contact protection of product internal relay and for noise reduction always insert a contact
protection device on the coil side of the buffer relay. In the controller also, a small type of contact protection
device is built-in for internal relay protection. Take care because a small leak current flows through this
contact protection device and load voltage.
Leak current is approximately 2mA when load voltage is 200V AC and it is approximately 1mA when load
voltage is 100V AC.
5. Alarm terminal
①Use the alarm terminal within the rating range. If a load that is out of range is applied, product may get out
of order, its performance may show a remarkable deterioration or it may malfunction.
②For alarm terminal always connect the load through buffer relay. For contact protection of product internal
relay and for noise reduction always insert a contact protection device on the coil side of the buffer relay.
6. Option terminal
①Use the option terminal within the rating range. If a load that is out of range is applied, product may get out
of order, its performance may show a remarkable deterioration or it may malfunction.
Precaution
①If a power supply that is out of range is connected, product may get out
of order, its performance may show a remarkable deterioration or it
may malfunction.
②If an excess current or excess voltage is applied to input output
terminal of the controller, the controller may get out of order, its
performance may show a remarkable deterioration or it may
malfunction.

[Controller] [Controlmotor]
In the above diagram, the controller and control motor manufactured by our company are directly connected
however, while actually connecting always insert a buffer relay and then connect. Futhermore, always connect a
contact protection device in control relay output terminal.
The contact protection device attached to the controller is for the motor (For load current 700 mA and above).
When connecting with buffer relay, use a contact protection device for light load. If the attached contact
protection device is used in buffer relay, operation defect occurs due to leak current.
For your reference symbolic name list of motors of various companies is given below.

2. Relay output wiring example
In relay outputs like ON-OFF pulse type, ON-OFF servo type and alarm output, always connect the load
through buffer relay and contact protection device.
[Controller]
Contact protection device is handled in our company also (See 16. Accessories).
When power supply is an AC power supply, and CR compound device, and power supply have direct current,
diode is generally used.
3. Wiring example of external signal input
In the figure on the left approximately
5V and 2mA is applied to the switch.
Take care about the contact point
capacity.
[Controller]
Various external signal inputs (DI) operate by short circuiting specified external signal input terminal and
common (COM) terminal. Operation by switch and relay is a general method however operation by open
collector output signal of peripheral device is also possible.
4. Wiring example of external signal output
The rating range of open collector
signalis less than maximum current
50mA,DC load, maximum voltage
24VDC.
Take care regarding the load
capacity.
[Controller]
Various external signal outputs (DO) are output using open collector signals. If AC power supply is applied or
load other than the rating range is applied, the controller may get out of order or its performance may deteriorate
remarkably or it may malfunction.
