MIU (Modem Interface Units)
AC/DC POWERED
SUBSTATION HARDENED
Communication Interface Units
To service the growing need for efficient, reliable data communications in the harsh environments of utility substations and industrial facilities, Data Connect has developed a family of data communications products that can operate from various AC/DC power supplies and survive high surge levels and extreme heat and cold. All this without compromising the performance expected from state-of-the-art communications devices.

With the rapid move toward “intelligent” substations, where meters, relays, RTUs, SCADA systems, etc. are able to “talk” to a remote operator, communications devices such as modems are moving off the desk top and into the field, where the conveniences of 115VAC power outlets and climate control are usually hard to find.

Data Connect has addressed this problem by developing a range of Communication Interface Units (CIUs) designed specifically for harsh environments.

The MIU2.4, 9.6, 14.4, and 28.8 are highly sophisticated full duplex, V.22bis, V.29 or V.32bis data modems that are designed to interface with RS232, RS485 (external device), 5V logic (TTL) or simple send and receive signals. They operate at full or half duplex on dial-up or 2-wire and 4-wire leased line systems.

All of these devices are powered from a unique power supply that enables them to operate on any AC or DC voltage ranging from 48V to 220V. A low voltage version (9-36VDC) is also available. The CIUs are designed to work in temperatures from -40 degrees C to +85 degrees C, and are surge protected on both the power and analog lines.

All of this is bundled in a 5-3/8″ x 4″ x 1-3/8″ non-metallic enclosure, suitable for desktop or wall mounting.
