Note) Panel coating procedure must be taken into account, for the panel cutout dimension should still
conform with the dimensions listed in the left hand column.
Caution on side-by-side installation:
• Maximum ambient temperature is at 45 ˚C when the power supply is at 200VAC or more. When
the PXR4 controller is tightly fixed in vertical and upright direction, the use of 100V AC power
supply is recommended .
(Installation of fan is recommended as a heat release measure)
• Make sure the controller is installed more than 30mm away, when there is an instrument of
more than 70mm depth or a wall on the right side of the controller.
• Side-by-side installation may sacrifice the controller’s waterproof property.
Caution on wiring:
• Terminals at the left hand side (from No.1 to 6) should be used first.
• Crimp terminals with matching screw size should be used. Tightening torque value should be
approx. 0.8N · m.
• Do not connect anything to the terminals that are not used. (Do not use as relay terminal)

Note 1 : Check the power supply voltage before installation.
Note 2 : Connect the I/V unit (250Ω resistor) (accessory)
between the terminal !7 and !8 in case of
current input.
In the case of 1 digital input
point (the 11th, 12th, or 13th
digit of the code symbol is “S00”),
connect the digital input terminal
between terminals u and i.
In the case of 2 digital input points + heater break alarm,
or 2 digital input points + remote SV specifications, connect the CT
input and remote input terminals between terminals !1 and !2.
