2.PRODUCT OVERVIEW

The MIU2.4, MIU9.6, MIU14.4 & MIU28.8 are industrial grade dial modems for connection to the Public Switched Telephone Network.. They can be powered from a wide range of AC and DC power supplies, they are internally surge protected on both the power and analog lines, and they will operate in temperatures from -40 to +85 deg C.

Internally, each unit consists of a baseboard and a communication module. The baseboard includes the power supply regulation and surge protection. The communication module is a Telenetics™ Pony Express™ Dial Modem Module.

The MIU is packaged specifically for the harsh environments found in utility substations and industrial facilities. Though functionally similar to commercial modems, the MIU includes special features that make it particularly well suited for utility and industrial applications:

Environment: The MIU has been designed specifically for use in harsh environments. In addition to an extended temperature range (-40 to +85º C), the MIU includes surge, shock, vibration, and safety features superior to those of conventional commercial modems.

Power Supply: The MIU can be powered from a broad range of AC and DC power supplies, such as an auxiliary supply (eg; 12VDC) from another piece of equipment, 125VDC from a station battery or a standard 120VAC.

Low Power: The MIU dial modem can be configured to enter into a “power down” mode. In this mode, an MIU will consume only a small fraction of its active power while waiting for either controller or telephone activity.
