S8V-CP

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

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.

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.

Turning ON all outputs during in the Current tripping (enable to reset) state is called reset. Output terminals in the Current tripping (enable to reset) state 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.

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.

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.

Note: If the power rating of the power supply unit is insufficient, the voltage of all the outputs may drop due to the overcurrent protection characteristic of the power supply unit.
To achieve tripping according to the above characteristic, select the required power rating of the power supply unit by adding the cutoff current value in addition to the normally flowing output current and the power consumption of the S8V-CP.
(Please refer to Recommended power supply unit)

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.
3. If the power rating of the power supply unit is insufficient, the voltage of all the outputs may drop due to the overcurrent protection characteristic of the power supply unit. Please refer to Recommended power supply unit.

In order to cut off only the abnormal circuit, please select a power supply unit using the table below.

Note:
1. Recommended when using all outputs. Please ask your OMRON representative for recommended power supply units when using under other conditions.
2. When using the S8VK-WA20224, make sure that the input current is less than or equal to the allowable input current of the S8V-CP0824.
