TDW-33 Modem

Description

Westermo Dial-Up RS-232/V.90 Modem, 12-48 VDC, DIN-Rail Mount

The TDW-33 is designed to function reliably within industrial environments and in areas of high level interference. The modem has an RS-232 interface supporting terminal data rates up to 115-kbit/s. The TDW-33 is a V.90 modem meaning that it can support data rates of up to 56 kbit/s on the PSTN line side. The modem is equipped with transient protection on the line side and a "watchdog" that monitors and automatically resets the modem in the event of a fault. These functions together with remote configuration make the modem perfect for installation at unmanned sites and prevent the need of costly service trips. The modem also has password protection, dial-back security and caller ID answering to ensure that only authorized users can communicate with the modem and any connected equipment. The TDW-33 is ideal for industrial applications as it mounts easily on to a 35 mm DIN-rail, runs from 12 - 48-VDC power supplies, has screw terminal connections and is tri galvanically isolated. For ease of setup the modem is supported by the Westermo TD-tool configuration software. Drivers for Windows setup are also supplied.
