RS-232 Isolator

4 kV isolated RS-232 transceiver for the protection against external influences in compliance with standard IEC 61850-3

The RS-232 isolator protects your equipment against external influences in substations such as ESD, Surge, Burst in compliance with the standard IEC 61850-3. The used RS-232 transceivers have 15 kV ESD protection.

The RS-232 interface is galvanically isolated (up to 4 kV) between interface and telecontrol line (in the direction of RTU or control station). This is implemented with state of the art iCoupler®-technology. The monolithic air core transformers allow significantly higher data rates and insulation voltage than optocoupler, for example.

Operation as well as send and receiving activities are displayed by means of three LEDs. As an active device the RS-232 isolator can also be used as repeater to bridge longer distances. The operating voltage is 24V DC.

The device is designed to work stand-alone as well as with multiple isolators connected in series and supplied by a common 24 V port.
