ECINT1-11Description:
The INT1 interface converter is used to convert RS232 interface signals to an RS485 signal level. It is used if:
- Data transfer over a long distance is required which cannot be bridged by an RS232 interface. The distance between two stations can be max. 5000 m when using shielded RS485 cables.
- Electrical isolation is required for the interface.
- A PLC is to be connected to a network using an RS232 interface.
The INT1-11 interface converter is equipped with lightning protection.
