MIU28.8 Modem (AC power)

To service the growing need for efficient, reliable data communication in a harsh environments of utility substations and industrial facilities, has developed a 28800bps modem 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” substation, where meters, relay, RTU’s, SCADA systems, etc. are able to “talk” to a remote operator, communications devices such as modems are moving off the desktop and into the field, where the convenience of 115VAC power outlets and climate controls are usually hard to find.

Data Connect Enterprise has addressed this problem by developing the MIU28.8 series modem designed specifically for harsh environments.

The MIU28.8 series modem is a highly sophisticated full duplex, V.34 data modem that is designed to interface with RS232, RS485 (external device), 5V logic (TTL) or simple send and receive signals. The MIU28.8 series modem operates on dial-up system

The MIU28.8 series modem is powered from a unique power supply that enables it to operate on any AC or DC voltage ranging from 48V to 240V. A low voltage version (9-36VDC) is also available. The MIU28.8 modem is designed to work in temperatures from 40°C to 85°C, and is surge protected on both the power and analog lines.

The MIU28.8 series modem is bundled in a 5-3/8” x 1-3/8” non-metallic enclosure, suitable for desktop or wall mounting
