Non-voltage contact or PNP open-collector transistor output |
|
High [+5 V to +30 V DC (source current 0.04 mA or less)] : Effective
Low (0 to 0.6 V DC or open) : Ineffective |
Analog output (common in NPN output type and PNP output type) |
Notes:
1) |
Analog output is not equipped with the short-circuit protection. Do not short-circuit or apply voltage to them. |
2) |
Use shielded wires for analog outputs. |
Communication specifications (High function type)
The HL-G1 can be connected to upper devices of RS-422/485.
When upper device sends the request command, the HL-G1 series send the response command.

RS-422 1-to-1 connection
Notes:
1) |
The transmission data cable and reception data cable are both twisted-pair cables. |
2) |
The shield is connected to the 0 V side of the power supply line inside the sensor. |
3) |
Be sure to connect the signal ground. |
4) |
The sensor is of non-isolated type. Make sure that the potential difference between the sensor and RS-422 connecting device does not exceed 4V. A difference in potential in excess may cause the connecting device or the sensor to malfunction. |
RS-485 1-to-N connection
- Connectable up to 16 units.
- Please set the prefix with no duplication.
Notes:
1) |
The transmission data cable and reception data cable are both twisted-pair cables. |
2) |
The shield is connected to the 0-V side of the power supply line inside the sensor. |
3) |
Be sure to connect the signal ground. |
4) |
The sensor is of non-isolated type. Make sure that the potential difference between the sensor and RS-485 connecting device does not exceed 4V. A difference in potential in excess may cause the connecting device or the sensor to malfunction. |
5) |
The sensor has a built-in terminating resistor. Be sure to turn ON the terminating resistor of the terminating sensor. |
6) |
Perform transition wiring for the transmission path. |
7) |
Connect the wires according to the specification of the equipment. |
