Industrial telephone modem

Westermo has released the Model TD-35 Modem for Industrial Applications. The modem has features not available in "commercial grade" products such as; DIN Rail mounting, wide operating DC and AC voltages, Galvanic Isolation, Transient Protection on all ports and a "Watch Dog" timer function.

The TD-35 provides remote access to any device with a RS232, or 485/422 Serial Port such as PLC's, RTU's and Alarm Panels using the Public Telephone network. The TD-35 can also be used to dial in to a remote Ethernet Network using Westermo's ED-20 Industrial PPP Ethernet Router.

Caller-ID, Password protection and Dial-back capabilities ensure maximum protection against unauthorized access. DIP switch settings eliminate the need for use of AT commands. The TD-35 is Austel approved and can also be used on 2 or 4-wire leased lines.
