| PIN No | Signal name | Description |
|---|---|---|
| 1 | OUTPUT ON STATUS（CH1） | On when output is on (output through an open-collector photocoupler). *1 |
| 2 | OUTPUT ON STATUS（CH2） | On when output is on (output through an open-collector photocoupler). *1 |
| 3 | OUTPUT ON STATUS（CH3） | On when output is on (output through an open-collector photocoupler). *1 |
| 4 | OUTPUT ON STATUS（CH4） | On when output is on (output through an open-collector photocoupler). *1 |
| 5 | POWER ON STATUS | On when the power is on (output through an open-collector photocoupler). *1 |
| 6 | ALARM STATUS | On when a protection function (OVP, OCP, OHP) is activated or when an alarm signal (ALARM IN) is received. |
| 7 | STATUS COM | Status signal common for pins 1 to 6. |
| 8 | OUTPUT ON / OFF CONTROL（CH1） | Output on/off control using external contact input. |
| 9 | OUTPUT ON / OFF CONTROL（CH2） | Output on/off control using external contact input. |
| 10 | OUTPUT ON / OFF CONTROL（CH3） | Output on/off control using external contact input. |
| 11 | OUTPUT ON / OFF CONTROL（CH4） | Output on/off control using external contact input. |
| 12 | ALARM IN | All channel outputs are turned off when an alarm signal is received. |
| 13 | FRAME GND | External signal common for pins 8 to 12. *2 |
*1 Open collector output: Maximum voltage of 30 V and maximum current of 8 mA. The status common is floating (isolation voltage or less). It is isolated from the control circuit. *2 FRAME GND is connected to the chassis.
