HXII 33T DC Power Modem

VDC Powered modem designed for industrial use

Rugged modem designed for industrial use -
Dial up or leased line - temperature rated
High voltage surge protection -
AC Voltage and DC Voltage power



  The Hidex II V.34bis Industrial Grade Modem is the most versatile model for Dial up or leased analog telephone line interconnect.  The Hidex  HX II 33T offers speeds up to  56K dial up.  They are temperature tested, rugged modems designed for Industrial applications.  Directly connected to RTU’s, traffic controllers, variable message signs or any number or other applications, they communicate at 300 bps to 56kbps over analog telephone lines.  All HX models have High voltage surge protection on the telephone lines. The power converter delivers  5VDC from 100 to 240 VAC, 50-60 Hz with World Wide safety approvals and a locking connector to prevent vibration disconnects.  A wide voltage range of  DC power models are optional. Specify your choice of 9 to 72 VDC.
