The Hidex II V.92 Industrial Grade Modem is the most versatile model for Dial up or leased analog telephone line interconnect. The Hidex HX II 56T 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.
