All wiring must be completed before power is turned on to prevent electric shock, instrument failure,
or incorrect action. The power must be turned off before repairing work for input break and output
failure including replacement of sensor, contactor or SSR, and all wiring must be completed before
power is turned on again.
To prevent instrument damage as a result of failure, protect the power line and the input/output lines
from high currents with a suitable overcurrent protection device with adequate breaking capacity
such as a fuse, circuit breaker, etc.
A malfunction in this product may occasionally prevent alarm outputs, resulting in a possible hazard
to the devices connected to this instrument. Take appropriate measures in the end use to prevent
hazards in the event of malfunction.
Prevent metal fragments or lead wire scraps from falling inside instrument case to avoid electric
shock, fire or malfunction.
Tighten each terminal screw to the specified torque found in the manual to avoid electric shock, fire
or malfunction.

(2) Use this instrument within the following environment conditions:
• Allowable ambient temperature: −10 to +55 °C
• Allowable ambient humidity: 5 to 95 %RH
(Absolute humidity: MAX. W. C 29.3 g/m3 dry air
at 101.3 kPa)
• Installation environment conditions: Indoor use
Altitude up to 2000 m
(3) Avoid the following conditions when selecting the mounting location:
• Rapid changes in ambient temperature which may cause condensation.
• Corrosive or inflammable gases.
• Direct vibration or shock to the instrument.
• Water, oil, chemicals, vapor or steam splashes.
• Excessive dust, salt or iron particles.
• Excessive induction noise, static electricity, magnetic fields or noise.
• Direct air flow from an air conditioner.
• Exposure to direct sunlight.
• Excessive heat accumulation.
(4) Mount this instrument in the panel considering the following conditions:
• Provide adequate ventilation space so that heat does not build up.
• Do not mount this instrument directly above the equipment that generates large amount
of heat (heaters, transformers, semi-conductor functional devices, large-wattage
resistors).
• If the ambient temperature rises above 55 °C, cool this instrument with a forced air
cooling fan, cooling unit, etc. Cooled air should not blow directly on this instrument.
• In order to improve safety and the immunity to withstand noise, mount this instrument
as far away as possible from high voltage equipment, power lines, and rotating
machinery.
High voltage equipment: Do not mount within the same panel.
Power lines: Separate at least 200 mm.
Rotating machinery: Separate as far as possible.
(5) In case this instrument is connected to a supply by means of a permanent connection,
a switch or circuit-breaker shall be included in the installation. This shall be in close
proximity to the equipment and within easy reach of the operator. It shall be marked as
the disconnecting device for the equipment.
2.2 Dimensions
Dimension Unit mm
Panel cutout dimensions Unit mm
For mounting of the SA200L, panel thickness must be between 1 to 10 mm.
When mounting multiple SA200L close together, the panel strength should be
checked to ensure proper support.
Installation Conditions:
The display cannot be seen from the outside of the visual field range. The
visual field range of SA200L is 40 degrees to the upper side, and 30
degrees to the lower side from the center of the display vertically.
2.3 Mounting Procedures
1. Prepare the panel cutout as specified in 2.2 Dimensions.
2. Insert the instrument through the panel cutout.
3. Insert the mounting bracket into the mounting groove of the instrument. (Fig.1)
4. Push the mounting bracket forward with a blade screwdriver until the bracket is
firmly secured to the panel. (Fig. 2)
5. The other mounting bracket should be installed the same way as described in
3. and 4.
When the instrument is individually mounted, always secure with two
mounting brackets either top and bottom or right and left.
In addition, the mounting assembly also includes two screws which can be
used with the brackets to secure the instrument to the panel. See Fig. 3.
The Waterproof/Dustproof optional on the front of the instrument conforms to
IP66 (Checked and confirmed its compliance through the internal test at RKC)
when mounted on the panel. For effective waterproof/dustproof, the gasket
must be securely placed between the instrument and the panel without any
gap. If gasket is damaged, please contact RKC sales office or the agent.
Close Mounting
Secure the mounting brackets in the positions as shown in Fig.4 and Fig.5.
If the SA200L have
waterproof/dustproof options,
protection will be
compromised and not meet
IP66 by close mounting.
Two SA200L cannot be
inserted into a panel cutout
of 48 × 48 mm.
3. WIRING
3.1 Wiring Cautions
• For thermocouple input, use the appropriate compensation wire.
• For RTD input, use low resistance lead wire with no difference in resistance between the
three lead wires.
• To avoid noise induction, keep input signal wire away from instrument power line, load
lines and power lines of other electric equipment.
• Signal connected to Voltage input and Current input shall be low voltage defined as “SELV”
circuit per IEC 60950-1.
• If there is electrical noise in the vicinity of the instrument that could affect operation, use a
noise filter.
− Shorten the distance between the twisted power supply wire pitches to achieve the
most effective noise reduction.
− Always install the noise filter on a grounded panel. Minimize the wiring distance
between the noise filter output and the instrument power supply terminals to achieve
the most effective noise reduction.
− Do not connect fuses or switches to the noise filter output wiring as this will reduce the
effectiveness of the noise filter.
• Preparation time for contact output
Allow approximately 5 seconds for contact output when the instrument is turned on. Use a
delay relay when the output line is used for an external interlock circuit.
• Power supply wiring must be twisted and have a low voltage drop.
• This instrument is not provided with an overcurrent protection device. For safety install an
overcurrent protection device (such as a fuse) with adequate breaking capacity close to
the instrument.
− Fuse type: Time-lag fuse
(Approved fuse according IEC 60127-2 and/or UL 248-14)
− Recommended fuse rating:
Rated current 0.4 A
• For the current input specification, an external resistor (250 Ω ±0.02 %, 0.25 W or more,
±10 ppm/°C) must be connected between the input terminals. For external resistor (shunt
resistor), use the KD100-55 (RKC product). If this resistor is installed, close vertical
mounting is not possible.
• For an instrument with 24 V power supply input, supply power from a “SELV” circuit
defined as IEC 60950-1.
• A suitable power supply should be considered in the end-use equipment. The power
supply must be in compliance with a limited-energy circuit (maximum available current
of 8 A).
• If the grounded type sensor is used, do not ground output wiring. Do not connect any
output wires to the terminals with any other output wires.
3.2 Restrictions on Wiring
• Always use recommended solderless terminal lugs or equivalent.
Screw size: M3 × 6 (With 5.8 × 5.8 square washer)
Recommended tightening torque: 0.4 N・m (4 kgf・cm)
Applicable wire: Solid/twisted wire of 2 mm2
Recommended solderless terminals: Circular terminal with isolation
(M3 screw, width 5.5 mm, hole diameter 3.2 mm)
Recommended dimension:
• Make sure that during field wiring parts of conductors cannot come into contact with
adjacent conductive parts.
• Always connect external wires starting from the lower terminals (No.1 to 6).
Disconnect the wires starting from the upper terminals (No.7 to 12).
• When multiple instruments are vertically closely mounted, do not connect two or more
solderless terminal lugs to one terminal.
• If multiple instruments are vertically closely mounted, it is necessary to bend the
terminal lugs when they are connected to the lower terminals.
