DESIGNED FOR HARSH ENVIRONMENTS
To service the growing need for efficient, reliable data communications in the harsh environments of utility substations and industrial facilities, Raymar-Telenetics has developed a family of data communications products that can operate from various AC/DC power supplies and survive high surge levels and extreme temperatures. 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 desktop and into the field, where the conveniences of 115VAC power outlets and climate control are usually hard to find.Raymar-Telenetics has addressed this problem by developing a range of Communication Interface Units (CIUs) designed specifically for harsh environments.
OPERATION & INTERFACE
The MIU is a highly sophisticated full duplex data modem that is 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 240V. A low voltage version (-9 to -36VDC) is also available.
The MIUs are designed to work in temperatures from -40 °C to +85 °C, and are surge protected on both the power and analog lines. All of this is bundled in a 5″ x 4-1/4″ x 1-1/4″ aluminum enclosure, suitable for desktop or wall-mounting.
