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. The Raymar-Telenetics Myriad Rack Mount Modem Bank is an industrial grade, 19" 3U (5.25"H) chassis with slots for 18 modem cards and 2 power supply cards. Each modem rack can be installed with many of Raymar-Telenetics modem cards, from Bell 202T to V.32bis. The Raymar Telenetics Myriad rack can be powered from a wide range of AC or DC voltages. Two power supply cards can be installed to provide automatic back up in the event the primary power supply fails. The Raymar-Telenetics Myriad rack will operate in temperatures from -20°C to 85°C and is surge-protected on both the power and analog lines.
