Ratings, Characteristics, and Functions
*1. For power input terminals, use 35 A max. per pole.
*2. A voltage drop will occur in the S8V-CP. Consider the voltage drop at the output.
*3. When selecting the power supply, be sure to include the power consumption of the S8V-CP and not just the power consumption of the load.
*4. Outputs start in order from +VO1 to +VO8. +VO1 starts after the initialization time. Start-up delay time of each output is automatically decided
depending on the load. If the start-up delay time is over 5 s, the next output is forcibly started.

Tripping Functions
Current tripping
If the output current of each output exceeds the current tripping, the output is tripped by a semiconductor switch (MOS FET) in accordance with
the current tripping characteristic.
Over voltage tripping
With the S8V-CP0424S, if the input voltage exceeds 28.8 V, all outputs are tripped by a semiconductor switch (MOS FET).
If the input voltage becomes 28.8 V or less, all outputs automatically return to the previous state.
Reset Signal Input (RST)
Turning ON all outputs during in the Current tripping (enable to reset) state is called reset. All output terminals can be reset by an external input.
As shown in the following figure, input a high level signal of 0.5 s or more and reset.
Input voltage: 30 VDC max.
Input impedance: 22 kΩ
Note: 1. When Reset signal input terminal is used, a miss operation of reset may occur by a noise coming from the cable. Do not make an instable
potential of Reset signal input terminal.
Alarm Signal Output (ALM1/ALM2)
If any of the output is tripped, the MOS FET relay is turned OFF. The signal output comprises of MOS FET relays and therefore, does not have
polarity.
Input voltage: 30 VDC max., Input current: 50 mA max.
Residual voltage when ON: 2 V max.
Leakage current when OFF: 0.1 mA max.
Note: 1. Alarm signal output is not equipped with an internal current limiting circuit, so be sure that the current flowing to the alarm signal output
terminals does not exceed 50 mA.
2. Be sure to check that the Alarm signal outputs are working normally after wiring.
Output Status
The status of each output can be identified by the indicator or alarm signal output.
The status of each output is saved when the power is turned OFF. When the power is turned ON again, the status transits to that saved after
initialization.
All outputs are set to Output ON state by default.
*1. Each output transits automatically to Current tripping (disable to reset) state according to the Current tripping characteristics.
*2. The status remains on Current tripping (disable to reset) state during 500 ms to 20 s in order to protect the internal parts from heat.
After that, the status automatically transits to Current tripping (enable to reset) state.
*3. S8V-CP0424S only
*4. If an internal fuse blows, or an internal memory error occurs, the output will be disconnected.
*5. Always remove the cause of the output first and then reset the alarm when abnormal tripping operates.

Input Voltage
• The S8V-CP0424S provides over voltage tripping function. All
outputs will be tripped if the input voltage exceeds 28.8 VDC.
However, this function does not protect loads and internal parts
from high voltages in all cases.
Use the input voltage within the rated range.
• The S8V-CP0424S may operate the over voltage tripping for loads
that generate reverse peak electromotive force.
• The S8V-CP operates by DC input. Do not connect an AC power
source to the power input terminal.
Input Power Supply Selection
• Depending on the overcurrent protection characteristics of the
power supply connected to the input side can cause the failure of
S8V-CP operating or tripping by voltage drop occasionally.
• If the input power supply starts or stops too slowly, the overcurrent
protection characteristics of the power supply can cause the failure
of S8V-CP operating or tripping by voltage drop occasionally.
Tripping Performance
• Always remove the cause of the output first and then reset the
alarm when current tripping operates.
• When using a load that operates with constant power, the current
may be tripping when the power is turned OFF.
• Do not repeat the tripping and reset operations more than
necessary. Internal parts may possibly deteriorate or be damaged.
• Tripping performance depends on the ambient operating
temperature. Use the Product within the derating curve (see
Derating Curves on page 7).
• Internal parts may possibly deteriorate or be damaged. Do not use
the Product for applications with frequent inrush current or
overloading at the load end.
Dielectric Strength Test
• Always short the all terminals of the Product so that the voltage is
applied at the same time.
• There is no insulation between the power input terminal and the
output terminal. Do not perform dielectric strength tests or other
insulation appraisal testing between inputs and outputs.
Connecting the S8V-CP
It is possible to connect multiple units of this Product as shown below.
Serial connections, such as connecting an S8V-CP to the output
terminal of another S8V-CP, can not be established.
Do not establish a parallel connection with other outputs. Also, do not
establish a parallel connection between the output terminals of two
S8V-CP.
Rated output current selector switch
The rated output current selector switch may possibly become
damaged. Do not apply more than the required force.

Connecting Backup Devices
Observe the following precautions when using a backup device, such
as one from OMRON's S8T Series.
• When a backup device is connected to the S8V-CP output, backup
current is supplied to the other output through the internal circuit,
and at the same time, internal components may be degraded or
damaged. When you use a backup device together, be sure to
connect it to the power input side of the S8V-CP.
• If you connect the backup device to the S8V-CP input terminal, the
backup time will be shorter than usual due to the consumption of
internal power. Always confirm the backup time when using a
backup device.

the release hole.
2. With the flat-blade screwdriver still inserted into the release hole,
insert the wire into the terminal hole until it strikes the terminal
block. Always twist stranded wires together before inserting them.
3. Remove the flat-blade screwdriver from the release hole.
Checking Connections
• After the insertion, pull gently on the wire to make sure that it will
not come off and the wire is securely fastened to the terminal block
• If you use the recommended ferrule, part of the conductor may be
visible after the ferrule is inserted into the terminal block, but the
Product insulation distance will still be satisfied.
Removing Wires from the Push-In Plus Terminal
Block
Use the following procedure to remove wires from the terminal block.
The same method is used to remove stranded wires, solid wires, and
ferrules.
1. Hold a flat-blade screwdriver at an angle and insert it into the
release hole.
2. With the flat-blade screwdriver still inserted into the release hole,
remove the wire from the terminal insertion hole.
3. Remove the flat-blade screwdriver from the release hole.

Recommended Replacement Periods and Periodic Replacement for
Preventive Maintenance
The recommended replacement period for preventive maintenance is greatly influenced by the installation environment of the Power Supply. As
a guideline, the recommended replacement period is 7 to 10 years.*
To prevent failures or accidents that can be caused by using a Power Supply beyond its service live, we recommend that you replace the Power
Supply as early as possible within the recommended replacement period. However, bear in mind that the recommended replacement period is for
reference only and does not guarantee the life of the Power Supply.
Many electronic components are used in the Power Supply and the Power Supply depends on the correct operation of these components to
achieve the original Power Supply functions and performance. However, the influence of the ambient temperature on aluminum electrolytic
capacitors is large, and the service life is reduced by half for each 10°C rise in temperature (Arrhenius law). When the capacity reduction life of the
electrolytic capacitor is reached, the Power Supply failures or accidents may occur. We therefore recommend that you replace the Power Supply
periodically to minimize product failures or accidents in advance.
*The recommended replacement period applies under the following conditions: rated input voltage, load rate of 50% max., ambient temperature
of 40°C max., and the standard mounting method.
This product model is designed with a service life of 10 years minimum under the above conditions.
