Worldwide network access via modem and Ethernet

With dial-up line connections, the new analog V.92 Ethernet modem PSI-MODEM/ETH from Phoenix Contact enables worldwide access to industrial Ethernet networks in machines and systems.


The option of checking a system or machine remotely online in the event of a malfunction will drastically reduce the travel expenses of your service technician in the future.

All control systems and operation panels of an Ethernet network can be controlled remotely via only a modem and a telephone line.

After successful authentication, the PSI modem gives the PC an IP address during dial-up, from which the PC can address all Ethernet devices.

Secure encryption

Security is ensured by the CHAP protocol (Challenge Handshake Authentication Protocol) with 128-bit password encryption and continuous reauthentication, which prevents unauthorized access.

This means that remote monitoring and diagnostics of distant network devices becomes as simple as dialing into the Internet at home.

With PSI-MODEM/ETH, all distant Ethernet devices can be reached worldwide via phone lines.
