LA-A1
NPN output type
|
| Symbols･･･ | D1：Reverse supply polarity protection diode D2：Input protection diode ZD1, ZD2, ZD3 : Surge absorption zener diode Tr1, Tr2 : NPN output transistor |
|---|
| Non-voltage contact or NPN open-collector transistor |
 |
| External synchronization input (Voltage between ES+ and ES– ) Low: 0 to 1 V High: +V or open |
| Notes: 1) | When ES+ (pink) and ES– (pink/blue) of external synchronization input are connected, both HIGH and LOW comparative outputs are triggered in the mode selected by the external synchronization selection switch. If the external synchronization function is not used, always short-circuit ES+ and ES– and set the external synchronization selection switch to gate trigger. |
|---|---|
| 2) | To use the analog output (gray), choose a device with an input impedance of 1 MΩ, or more, and connect the shield wire of the analog output to 0 V (common input) of the device. |
| 3) | Insulate all unused wires individually to avoid miscontact. |
