Industrial Data Communications Products

Data communications in industrial and institutional environments can present special problems. Lines must be run over long distances, often ranging from thousands of feet to several miles, indoors and outdoors, and between buildings. Such data communications systems must be able to function in the presence of electrical transients and noise, ground loops, and surges from nearby lightning strikes.

Dataforth Corporation's rugged modems, rack-mounted modem systems, and new DCP485 series of DIN-mount, fully isolated RS-232/RS-485 converters are designed to "harden", protect, and extend the operating ranges of these data communications networks while providing additional benefits in reduced installation and maintenance costs.  

Industrial LANs and data communication systems stretch over long distances, inside and outside, with signals exposed to electrical transients, noise, ground loops, power surges, and lightning. Commercial communications equipment often is not designed for use in these environments, which can lead to unreliable signal quality, damage to expensive CRTs, computers, and other online equipment, and production downtime. Our heavy duty modems “harden” and protect these systems, and can extend communications for many miles without expensive cabling.

Our LDM Series limited distance modems protect host computers and equipment and extend the distances over which computers, terminals, and other devices can communicate within hazardous industrial and institutional environments – up to 12 miles using wire pairs and current loop protocols, or two miles with fiber optic data links for total electrical isolation. 

Our DCP485 DIN Rail RS-232 to RS-485 converter/line driver provides 1500 Vrms continuous isolation and data transfer up to 115.2 kbps with automatic RS-485 line control while powered from +10 to +30 VDC. 

Our RML100 rack-mounted modem system lets users organize up to 28 data channels at a single site while providing 300V optical surge isolation and speeds up to 57.6kbps.
