The TD-35 is a high quality V.34 PSTN and leased line modem designed
for use in harsh industrial environments. To make installation
and maintenance easy all the connections are at the front and the
modem is designed to snap easily onto a DIN rail. Fault diagnosis
is made simple with the inclusion of a number of LED indicators.
The TD-35 is suitable for many applications including remote connection
to PLC’s, energy meters or data loggers.
The TD-35 has a number of features not found in standard modems
including complete tri-galvanic isolation, DIP switches for configuring
popular AT commands and a watchdog function. The watchdog monitors
internal hardware and software as well as the power supply. If
any problems are detected the modem will be reset leaving the modem
ready to receive the next call or to negotiate a new leased line
connection. This feature makes the TD-35 ideal for use on unmanned
sites.
The TD-35 has two variants, one which supports just RS-232 and
one that can be used with RS-232 or RS-422/485. Both variants are
available as either an LV(12–54VDC, 12–27VAC) or HV
(95–240V AC, 110–240 V DC). |
