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.
*5. Refer to Tripping Functions on page 3 for details.
*6. Refer to Current Tripping Characteristics and Current and Voltage Tripping Characteristics on page 7 for details.
*7. MTBF is calculated according to JEITA RCR-9102.
*8. Refer to Recommended Replacement Periods and Periodic Replacement for Preventive Maintenance on page 14 for details.
*9. UL Class 2 output applies for the S8V-CP0424S model only.

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.

Engineering Data
Derating Curves
Current Tripping Characteristics
S8V-CP0424, S8V-CP0824
Note: If the power rating of the power supply unit is insufficient, the overcurrent protection characteristic can cause a voltage drop in all the outputs.
In order to trip the current according to the above characteristic, select a power supply unit with a current higher than the total tripping current
considering the power consumption of the S8V-CP.
Current and Voltage Tripping Characteristics
S8V-CP0424S
Note: 1. Input voltage 24 to 28.8 VDC tripping current is decreased to less than 3.2 A in accordance with the current and voltage tripping
characteristic.
2. Current tripping takes place between 250 ms to 5 s.
